Overview of Domestic Application of the Roll Crusher

Wed, 22 Aug 2012 08:19:00 GMT

The roll crusher was used in industrial production in 1806, which is a relatively old crushing equipment. Since the roller crusher can crush the wet clay, coal and other soft material with its simple structure, easy maintenance and low price,the roll crusher is still widely used in cement companies. The main working part of the roll crusher is the cylindrical roller. Some roller surface is smooth glossy and some is the ribbed or toothed uneven surface. In addition, different roller sleeves with different shapes can be installed according to different applications. According to the number of roller, the equipment can be divided into single-roll crusher (PG), double roll crusher (2PG) and multi-roll crusher (4PG, 6PG). According to the shape of the surface of the roller, it can be divided into glossy roller crusher (PG) and tooth surface roll crusher (PGC).The roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production. Compared with the jaw breaker and mobile crusher, the roll crusher has longer history.The specification of the roll crusher is indicated by diameter x length (mm) of the crusher roller. For example 2PGC900 × 1200 means that roller diameter of the tooth surface double roll crusher is 900mm, and the length of the roller is 1200mm. For a single-roll crusher, it has a toothed surface of the roller sleeve of the roller which forms a crushing chamber with the jaw plate. When the material enters the crushing chamber, with the downward rotation of the tooth surfaces roll in the role of friction, the material drawn into a gap between the roller and the jaws, the extruded material will be pulverized. Meanwhile, the pulverized material is immediately transferred roller. For double roll crusher, the main structure is characterized by the two rollers to retain a certain distance. The roll crusher uses compression, with two rolls rotating around a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product required, with the realization that the largest feeding particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

How to Choose Suitable Mining Vibrating Screen

Wed, 22 Aug 2012 08:17:00 GMT

For the selection of the mining vibrating screen, there are many people are confused and they do not know how to choose, because there are many kinds of vibrating screens. If you want to choose a suitable mining equipment screening machinery, you must first understand the structure and working princes, the advantages and disadvantages and the scope of the applicability of the vibrating screen.Now the experts of Henan Hongxing Mining Machinery will talk about several common types of screening machinery.First,let us talk about the plane movement screen. The body is one plane. The plane trajectory is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking screen and vibrating screen belong to this category. Second, we will introduce the roller screen. The working face is composed by the horizontally arranged root scroll axis shaft. There are plates on the bearing. The fine materials go through the gap between rollers and plates. The bulk materials is driven by the roller to one end and discharged from the end. The concentrators rarely use this screen. Third, we will introduce the shaking screen. The crank linkage is regarded as the transmission part. Motor is rotated via a belt and pulley drives the eccentric shaft for rotation. The body moves with the connecting rod for reciprocating movement along a certain direction. The direction of movement of the body is perpendicular to the strut or the center line of the hanging rods. The material on the screen is moved to the discharge end with certain speed due to the swinging motion of the body so that the material also be sieved. Compared with the above screens, the productivity and the screening efficiency of the shaking screen is higher. The disadvantage is that the driving force is poorly balanced. The concentrators rarely use it, and the structure is replaced by more reasonable vibrating screen.Forth, we will talk about the fixed screen. The working parts are fixed and slide along the working surface and make the material screened. The fixed grid screen is common used in the concentrator for rough crushing and the pre-screening before medium crushing. It is simple in structure with convenient manufacture. It dose not consume power and it can directly unload the ore to the screen surface. The main drawbacks are the low productivity and low screening efficiency.Fifth, we will introduce the cylindrical screen. The working part is cylindrical. The entire screen rotates around the axis of the cylinder. Spiral separator : http://www.ore-machine.com/spiral-classifier.htmlImpact crusher : http://www.crusher-export.com/impact_crusher.htm

There Is Gap Between Domestic and Foreign Jaw Crusher

Wed, 22 Aug 2012 08:15:00 GMT

With the further research of the domestic and foreign experts for the jaw crusher, people have put forward higher requirements for the performance of the jaw crusher. This makes the structure of the crusher perfect and improves equipment performance. The parameters matching is more rationalize. With the wide application of the jaw crusher to a crushing equipment in various industries such as metallurgy, coal preparation, mines and other industries. The jaw crusher has also become the most common used equipment used in crushing projects. When the the simple pendulum jaw crusher is gradually replaced by the the compound pendulum jaw crusher and the compound pendulum jaw crusher is widely used, new crushing equipment has appeared, such as the deep cavity dual-chamber crusher, double action jaw crusher, fine crushing jaw crusher. However, there is a gap between the most domestic jaw crusher and the advanced level in the world. For example, in terms of cavity design, most of the domestic jaw crusher is straight cavity shape.At present, many domestic manufacturers and design units rely on their experience or refer to the design parameters of the foreign crusher to produce and design the crushing machine. They do not form their own equipment design concepts. Compared with the design philosophy of the foreign-crushing equipment, there is a big gap between the crushing equipment in China and foreign countries in terms of simulating dynamic runtime analysis test. For this new type of crusher jaw crusher outside the moving jaw evenly crusher, the introduction of dynamic design means are introduced to restore the real working conditions of the crusher and simulate its performance under the given constraints to analysize its structure. The jaw crusher is optimized based on simulation results.The strip and strip pulley are driven by a motor, and the moving jaw moves up and down via eccentric shaft. The angle between fixed jaw and moving jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It will become bigger when the moving jaw runs up. The moving jaw board leaves the fixed jaw board under the action of pole and spring, and then the end products come out from the crushing cavity. CAD technology provides application basis for the sustainability and manufacture of traditional crushing equipment. Product parametric modeling and solid model CAD technology are given, which is the basic feature of this technology in the design phase. We apply parametric design capabilities of Pro / E software to achieve a parametric design method of the compound pendulum jaw crusher crushing tooth plates with the entity model.

Jaw Crusher Has a Promising Development Prospect

Wed, 22 Aug 2012 08:07:00 GMT

The advent of the jaw crusher was in 1858 with 100 years of history. In order to meet the customers’ demand, the manufacturers continuously improve and innovate the equipment structure. The performance has been greatly improved, but there is no fundamental change of the basic principle which still basically belongs to the static extrusion broken. The jaw crusher produced by different enterprises has different characteristics and size specifications, models and performance. Most mechanical plants mainly produce the small and medium-sized jaw crusher. The jaw crusher is mainly divided into the simple pendulum jaw crusher and the compound pendulum jaw crusher. The manufacturing technology in recent years has experienced three stages of imitation with the similar equipment, improvement and self-based sauce. The jaw crusher has basically reached the localization and the formation of a product line. Particularly the updating the design of the structure and performance makes the equipment more reasonable and advanced. In the process of update and the design of the compound pendulum jaw crusher, Henan Hongxing Mining Machinery appropriately reduces the suspension height of the moving jaw, increases the the crushing chamber volume, narrows eccentric distance, reduces tooth angle with screw or hydraulic shim adjustment device to improve the shape and materials of the lining (pad) so that the trajectory of the moving jaw is more reasonable. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. The adjust operation is more convenient and the maintenance cycle and service life may be extended. The crushing efficiency and production capacity were significantly improved with significant technical characteristics. This series of jaw crusher have many advantages, such as big crushing ratio, even granularity, simple structure, reliable working condition, convenient repair and economical operation. They are widely used for crushing minerals, smelting, building materials, chemicals and other materials. In recent years, the energy has become scarce. In order to meet the requirements of the fine crushing operations of the building materials, road construction, mineral processing, chemicals and electricity, the beneficiation and grinding strives to increase and save energy. Henan Hongxing Mining Machinery Co., Ltd. has formed a series of primary jaw crusher and the development prospect is optimistic.

How to Operate the Jaw Crusher in a Correct Way

Wed, 22 Aug 2012 08:04:00 GMT

The jaw crusher is widely used for medium crushing and fine crushing the ores and rocks with various hardness in metallurgy, mining, chemical, cement, construction, refractories and ceramics and other industrial sectors. The jaw crusher has the characteristics of great crushing ratio, simple structure, reliable work, uniform particle size, operating cost, easy maintenance and so on. The jaw crusher can crush the various soft and hard ore whose crushing gravel equipment compressive strength is not higher than 300MPa (MPa). The correct operation of the jaw crusher: After the preparation work, you should operate the machine according to the required order. When you start the main motor, you should pay attention to the system cabinet ammeter. After the start of 30 ~ 40s peak current, the current will be reduced to the normal work current value. In normal operation, the current should not exceed the specified value for a long time. After the normal operation of the crusher, you can actuate the feeder, and adjust the rotational speed of the feeder in order to change the volume of feed according to the size of the feed block and the operation situation of the crusher. Usually, the accumulation of material in the crushing chamber should be more than 2/3 of the height of the crushing chamber. The diameter of the material block is preferably not more than 50% into the feed port width. At this time, the production capacity of the crusher is the highest. When the diameter of the material block is 80% of the feed port width, the production capacity will be decreased significantly. If the material block is larger, it will cause congestion which will affect the normal production. The check preparation of the jaw crusher before starting:Carefully check if the main parts of the crusher are normal, such as jaw plate, bearings, connecting rods, thrust plate, rod springs, pulleys and V-belts and others. Fasten the bolts and other connection parts. Check if the protection devices are intact, such as pulley, flywheel housing. Check the auxiliary equipments are intact, such as feeders, belt conveyor, lubrication station, electrical, instrumentation and signal equipment. Check if there is material in the crushing chamber. If there are large pieces of material, you must removed the material before you can start the crushing chamber.

New Material Is Applied to the Crushing Equipment

Wed, 22 Aug 2012 08:02:00 GMT

With the development of science and technology, the crushing equipment has been greatly improved in technology and also makes a breakthrough in the application of the equipment and materials. First, let’s talk about the plastic material.The material has the advantages of small specific gravity, strong corrosion resistance, good wear, friction performance and seismic resistance. In addition, the plastic material has sufficient mechanical strength, which can be compared with the metal material. In recent years, the proportion of plastic parts in military and civilian machinery products increased. Many countries have drawn up the plastic standards for the industrial sector selection.The moving jaw bear of the simple pendulum jaw crusher made in Japan uses the oily synthetic resin. The plastic is used to make the machine parts, which not only can save the metal to reduce weight, but also improves the performance of the machine to improve the reliability of the machine, extend the service life of the machine and reduce the production cost of the machine.The second material used in mining machinery is rubber. After years of trial studies. it confirms that the wear of the smooth manganese steel liner is twice faster than the flat rubber liner wear. The ribbed rubber liner wear occurs only at the top of the ribs, while there is no wear between the two tendons. The amount of wear of the rubber layer of the smooth rubber village board and a ribbed rubber liner within a unit time is equal. The consumption of ribbed rubber liner for per ton of material is only one-third of the smooth rubber liner. The wear of the rubber changes with the size, speed, and the hardness of the material of the device. The test in Sweden has demonstrated that the cost of the liner reduces by 5% after the discharging end of the mill, feeding end and the carcass use rubber liner. In addition, the installation time is 2.5-3 times faster than the manganese steel. Meanwhile, it is possible to reduce the power consumption and weight of the machine, and to reduce the consumption of grinding bodies to extend the life of the liner. There is no noise when the mill is running, which can improve the working conditions. When the rubber liner is used to replace the steel liner, you can not use the wood or steel to fill with the cracks. The rubber liner must be connected. At the connection of the carcass and end liner, you should fill with a piece of rubber. The remaining gap should bu filled with cement. As the rubber sheet is easy to burn, so the installation work should be completed in the case of entirely fireproof.

Development of Jaw Crusher in Industrial Automation

Wed, 22 Aug 2012 08:00:00 GMT

With the rapid development of China's national economy, the comprehensive utilization of mineral resources and its industry develop rapidly. The material crushing is an indispensable process in the production in many industries (such as metallurgy, mining, building materials, chemicals, ceramics, road construction, etc.). In order to meet the requirements of a variety of materials, due to the physical properties of materials and structural differences, the mining machinery enterprises should produce different types of crushers. For the metal ore beneficiation, crushing is the first process of the concentrator. In order to separate the useful minerals, the crushing process can be divided into rough crushing, medium crushing and fine crushing. Since the crushing process consumes large amount of energy in the concentrator (about 50% of the power consumption of the whole plant), in order to save energy and improve production efficiency, the crusher develops towards energy-efficient direction of the fine crushing, grinding.In addition, with the development of industrial automation, the crusher is going forward the automated direction. For example, the foreign products have reached the hydraulic integration, continuous detection and automatically adjust the feed rate, discharge mouth size and crushing force. With the expansion of the scale of mining, the crushers are also developing towards large-scale. For example, the rough crushing gyratory crusher’s processing capacity has reached 6000th. The new principles and new ways of crushing (such as electrical, thermal fragmentation) is still in the research trials, it can not be used in the production yet. For coarse crushing, there is no new equipment to replace the traditional jaw crusher and gyratory crusher. We mainly use the modern technology to improve the machine to refine and improve the wear resistance and achieve energy-saving, high efficiency, long life purposes. There are more models in terms of fine crushing. Overall, the most widely used machine is the jaw crusher rather than the cone crusher.Traditional jaw crusher has the advantages of simple structure, reliable operation, easy manufacture, easy maintenance, low cost, and strong applicability, so it is widely used in the industry. The disadvantages are non-continuity crushing, low efficiency, small crushing ratio. For its shortcomings, many countries have improved the machine in the following aspects. Optimize the structure and trajectory to improve the crushing cavity to increase the crushing ratio and improve crushing efficiency, reduce wear, reduce energy consumption. The deep crushing chamber and smaller nip angle are widely used. We should improve the suspension type and lining support type of the moving jaw to improve the performance of the crusher. The jaw plate uses new wear-resistant materials to reduce the wear and tear. The level of automation has been increased. (automatically adjusts, overload protection, automatic lubrication, etc.)

Automation Cannot Be Separated from Control System

Wed, 22 Aug 2012 07:57:00 GMT

With the continuous development of society, the use of mining equipment slowly entered the era of automation and control area. In the modern control system, the mining equipment uses a number of new control devices and components, such as MP, MC, PC, crystal tray tube and so on to achieve the automation and control complex production process. Nevertheless, at present, the most extensive, the most basic control applied to China's industrial production is still the electrical control. Any complicated control circuit or system is composed of some relatively simple basic control links and the protection link. Therefore, mastering these basic control link is the basis to learn the electrical control circuit.The control circuit design, the production site installation, commissioning, analysis, maintenance failure of the mining equipment, such as the mobile crusher and impact crusher, the electrical schematics plays a very important role. Analysizing and reading electrical schematics needs a process. First, you should have the equipment to hang the impact crusher.The installer and operator should be familiar with the structure of Impact Crusher, characteristics and technical requirement, be acquainted with the necessary operating regulation and design the proper installation flow in advance. Then Check the hole for the base bolts is coincident with the draft and other design draft. The Impact Crusher must be installed on the reinforced concrete. The height, depth and area of base should be calculated according to the local field condition. The machine also can be installed on the steel frame. The base should be flat. The crossing plane of the body and the foundation can’t leak dust and the foundation bolts should be fastened. During installation of Impact Crusher, replacing or adjusting the hammers, pay attention to its weight. In the symmetrical position, its weight difference should be limited to the minimum. Before the first start and after a long time operation, check the distance between the bottom edge of the impact plate and the top of the hammers. Make sure the distance between the front impact frame and the hammers is twice that between the back impact frame and the hammers. The installation of the thrust bearing should be same to steps of scratching. When installing air eccentric shaft,the big gear weight should be placed in the top of small gear,so that the outer end of bevel gear is alignment. The electrical schematics is very important for the installation of the mining equipments. As a result, we should master the knowledge of the electrical schematics to better install the mining equipments to avoid unnecessary trouble.

Design Basis of Broken Tooth Height

Wed, 22 Aug 2012 06:10:00 GMT

The type of crushing teeth broken tooth type is generally divided into the olecranon, javelin and cutting edge style,and so on. the Commonly used are the first two, because it can better reflect the role of the material stretching and chipping principle. Javelin-style welded wear-resistant alloy javelin mounted in the the teeth roll javelin seat, the advantages of this type is to replace a broken tooth convenient, but the cost is too high. Olecranon style is designed according to the wear-resistant alloy casting molding and arched teeth - body panels, the cost is low, easier replacement, types of the olecranon broken teeth. According to the cross-sectional shape ,it can be divided into quadrangular teeth Goryokaku teeth and hexagonal teeth. Front corner and rear corner rectangular tooth contact with the material edge, this tooth type generally used for the crushing refuse less raw coal. Front corner and rear corner hexagonal tooth contact with the material, there is a certain width of blade, to better reflect the role of the principle of material stretching and chipping, generally used for crushing raw coal refuse amount. Goryokaku teeth rake angle is only in contact with the material or the posterior horn at the edge of a certain width, its application range is between rectangular teeth and six-rowed between the teeth. The height of the crushing teeth height is designed according to the size of the teeth radially along the tooth roller, referred to as the tooth height. Tooth height reasonable design can improve the processing capacity of the impact crusher, reduce the the crushing energy required and strict guarantee product granularity. If the tooth height design unreasonable, the content is two high , this can improve the ability to bite into a chunk of material, but it can also cause the the superscalar product size; if its too low, then will reflect with broken teeth rotating wire-speed spent ,The adverse effects caused by the same. Therefore, during the design of the tooth height, the response to the product limit on the rate of hammer crusher, for scientific analysis, such as the product limit on the rate of the most demanding, the tooth height can be designed for similar requirements and product granularity; such as the rate on the product limit the requirements are not strict, to improve the ability to bite into a chunk of material may be appropriate to increase the size of the tooth height.

Mining crusher refers to the crushing machinery whose total content is more than 50% ,the row compound particle size is greater than three millimeters. It is invented by British Hengan. according to the feeding and nesting size size, crushing operations are often divided into coarse crushing , medium crushing, and crushing. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, and so on. Breaking tooth width to the width of the crushing teeth refers to the size of the teeth in the axial direction along the tooth roller, referred to as the tooth width. Reasonable design of tooth width to strictly ensure product particle size and reduce the crushing rate and increase the strength of the broken tooth. Tooth width can not guarantee that the product design is too wide granularity; too narrow, decrease the broken tooth strength and increase the crushing rate. Due to the dimensions of the tooth width from the tooth root to the tooth tip is gradually becomes smaller, the tooth width of the tooth top at generally the tooth root of the tooth width of 3/4, the tooth width of the tooth root is generally preferably broken tooth pitch and product size difference. The length of the breaking tooth breaking tooth length refers to the dimension along the toothed roller circumferential direction of the teeth, Acronym tooth length. Rational design of long teeth ensure product granularity to improve the capacity and service life of broken teeth withstand impact loads. Tooth length is divided into addendum long tooth root ratio addendum long, about 20 ~ 40mm, tooth root length depends on the diameter of the gear rolls in the cross section of the same tooth roller breaking machine number of teeth and broken teeth rotate when the line speed of the design, the general design of the tooth root length along the circumferential direction of the gear rolls on the front teeth and rear teeth and in the spacing of the tooth at the root of about 10 ~ 30 mm.
