Roll crusher (senior roller)

Roll Crusher (Big Four Roller)

The main features of the double-roll crusher are: compact structure, stable operation, long service life, stable quality, flexible adjustment of crushing particle size, and easy maintenance. The operation of the machine is that the motor drives the driving roller through the hydraulic coupler and the reducer. The driving roller drives the passive roller through the gear box, and rotates relatively continuously at different speeds. The crushed material falls between the two rollers through the feeding port. , Squeeze and crush, and the finished material falls naturally. When encountering too hard or unbreakable objects, the rollers can automatically retreat under the action of the spring, so that the gap between the rollers increases, and the oversized or unbreakable objects fall down, thus protecting the machine from damage. There is a certain gap between the two rollers that rotate in opposite directions. By changing the gap, the maximum discharge size of the product can be controlled. This machine can crush 40mm materials to less than 10mm. In order to improve the service life of the machine, the rollers are made of high-quality wear-resistant alloy cast steel structure. The surface is quenched and tempered. The bearing seal adopts a two-layer sealing ring structure, which can be used for a long time without adding lubricating oil.

Product description

The main features of the double-roll crusher are: compact structure, stable operation, long service life, stable quality, flexible adjustment of crushing particle size, and easy maintenance.
The operation of the machine is that the motor drives the driving roller through the hydraulic coupler and the reducer. The driving roller drives the passive roller through the gear box, and rotates relatively continuously at different speeds. The crushed material falls between the two rollers through the feeding port. , Squeeze and crush, and the finished material falls naturally. When encountering too hard or unbreakable objects, the rollers can automatically retreat under the action of the spring, so that the gap between the rollers increases, and the oversized or unbreakable objects fall down, thus protecting the machine from damage. There is a certain gap between the two rollers that rotate in opposite directions. By changing the gap, the maximum discharge size of the product can be controlled. This machine can crush 40mm materials to less than 10mm. In order to improve the service life of the machine, the rollers are made of high-quality wear-resistant alloy cast steel structure. The surface is quenched and tempered. The bearing seal adopts a two-layer sealing ring structure, which can be used for a long time without adding lubricating oil.
This machine is mainly composed of transmission device, fixed shaft assembly, movable shaft assembly, cover assembly, frame assembly, linkage safety device, connecting plate gearbox and other parts, which can be widely used in cement, metallurgy, chemical industry, electric power, coal and other industries , Processing of brittle and ductile materials.

　The toothed roller crusher is suitable for the coal, metallurgy, mining, chemical, building materials and other industries, and is more suitable for the crushing of raw coal (including gangue) in large coal mines or coal preparation plants. The double-toothed roller crusher developed by our company is a new product designed and developed by ourselves with reference to the structure principle of foreign crushers.
This machine has the advantages of small size, large crushing ratio (5-8), low noise, simple structure, convenient maintenance, high productivity (1-2 times higher than that of my country's current 2PGC toothed roller crusher), and the particle size of the crushed material. Uniform, low crushing rate, easy maintenance, sensitive overload protection, safe and reliable. This machine mainly uses special wear-resistant toothed rollers to rotate at relatively high speed to split and crush the materials, forming a mechanism of high productivity.
The double-toothed roller is driven by a universal coupling, and the roller gap can be adjusted by a gasket. The machine is mainly composed of a fixed roller, a movable roller, a reducer, and a universal coupling. Very convenient.
　The 2PGCQ625×3000 strong double-toothed roller crusher developed by the company has the advantages of compact structure, large crushing ratio (5-8), low energy consumption, low noise, simple structure, convenient maintenance, and high productivity (compared to my country's current 2PGC toothed roller crusher has 1-2 times higher productivity), uniform particle size of the crushed material, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability, etc., which fills the domestic gap, and its main performance indicators are at the leading domestic level. . Main innovations: (1) The high wear-resistant and high-strength alloy material of the tooth plate increases the service life of the crusher; (2) The improved tooth height and tooth pitch of the original crusher greatly improve the discharge particle size. Breakability; (3) Upgraded the lubricating oil system of the machine, equipped with a dry oil lubrication station, and realizes the function of automatic oil supply when the machine starts; (4) Equipped with an automatic alarm function, if the lubricating oil occurs, other parts appear problem, it will automatically alarm.
2PGCQ625×3000 strong double-toothed roller crusher is a Shandong province innovation plan project undertaken by our company in 2004, and passed the provincial new product appraisal at the end of 2004. In 2005, 2PGCQ625×3000 strong double-toothed rollers set a new record for the tenth national enterprise.

The main features of the 4PG series four-roll crusher: it can simplify the crushing process and reduce the cost of use; it has the advantages of long service life and stable quality; the size of the discharge is adjustable, and it is easy to maintain.
The rotation of the machine is to use two motors to drive the upper driving roller and the lower driving roller to rotate through the four-roller coupling and the reducer respectively. Fall naturally, when encountering too hard or unbreakable objects, the rollers can automatically retreat by the action of the spring, so that the gap between the rollers increases, and the oversized or unbreakable objects fall down, thus protecting the machine from damage. The two rollers rotating in opposite directions have certain The maximum discharge size of the product can be controlled by changing the gap. This machine can crush 100mm material to less than 3mm.
In order to improve the service life of the machine, the roller is made of high-quality wear-resistant alloy cast steel structure, and its surface is quenched and tempered. After the surface of the roller is worn, it can be turned by the cutting device installed in the machine to ensure the smooth surface. Bearing seal The structure of two-layer sealing ring can be used for a long time without adding lubricating oil.
This machine is mainly composed of frame part, active roller part, passive roller part, transmission part, safety adjustment part, protective cover part, cutting part, etc. It can be widely used in cement, metallurgy, chemical industry, electric power, coal and other industries. and tough material processing.

The 4PG1200×1000 four-roller crusher is an innovative project of Shandong Province undertaken by our company in 2004, and passed the provincial new product appraisal at the end of 2004.
4PGC series toothed roller crusher has the characteristics of novel and reasonable structure design, large crushing capacity, high process efficiency and good economic benefit. It is a new type of crushing equipment with high efficiency, advanced technology and energy saving. The two-stage crushing operation of this machine is carried out in one body, the crushing ratio can reach 6-8, and the crushing efficiency can reach more than 99%.
This series of crushers can be used in coal, metallurgy, non-metallic mining, chemical and other industries. Crushing coal, coke, oil shale, chalk, graphite, kaolin, asbestos and other medium-hard materials. This series of crushers are especially suitable for the crushing of raw coal before coal preparation and classification because the particle size of the crushed materials is particularly uniform, and the phenomenon of super-granularity and over-pulverization is extremely rare.
