roll crusher consists of two oppositely rotating rollers

With simple working principle and compact structure, the roll crusher can effectively crush various materials of different sizes. For most of the brittle materials such as ores and coal, it has high crushing efficiency and uniform discharge size.

Features of roll crusher:

1. simple and compact structure: roll crusher has a simple design, small volume, small footprint, more convenient installation and maintenance.
2. large crushing ratio and strong crushing capacity: it can effectively deal with large feed size and achieve high production efficiency. With large crushing ratio, it is suitable for coarse and intermediate crushing of various materials.
3. low noise, smooth operation: the equipment in the operation of the process of low noise, smooth operation, can reduce environmental pollution.
4. uniform particle size, low over-crushing rate: the size of the crushed material is more uniform, and less over-crushing phenomenon, which makes the finished material higher quality.
5. wide range of crushed materials: able to crush materials with compressive strength not exceeding 160MPa, adapting to the crushing needs of different types of materials.
6. easy maintenance: simple design, reasonable structure, fewer failures, easy maintenance, reducing maintenance costs.
7. overload protection function: with sensitive overload protection system, to ensure that the equipment in the case of overload automatic shutdown to prevent damage.
8. energy saving and environmental protection: low energy consumption at work, and less dust produced in the operation of the equipment, which is conducive to environmental protection.

Working Principle of Roll Crusher:

1. Crushing Process: When the material enters the crusher, the two rollers rotate in opposite directions, pressing the material into the gap between the rollers. Due to the raised teeth on the surface of the rollers, the material is subjected to strong extrusion and shear force between the rollers, and finally the material is crushed into smaller particles.
2. adjustable discharge size: by adjusting the gap between the rollers, you can flexibly control the discharge size to meet the needs of different users.
3. over-crushing control: due to the design characteristics of the roller surface, the equipment can effectively avoid over-crushing, to ensure that the crushed material particles are uniform.

roll crusher application fields:

1. mining industry: used for crushing ores, especially for coal, iron ore, copper ore and other brittle ores with excellent crushing effect.
2. Metallurgical industry: used for ore pretreatment in smelting process, especially in the coarse crushing process before smelting, with high crushing efficiency.
3. Cement industry: It is used as raw material crushing equipment in cement production line, crushing limestone and other mineral raw materials to provide suitable size materials for subsequent production.
4. Chemical industry: widely used in the crushing of chemical raw materials, such as petrochemical industry in the crushing of some ores, chemicals.
5. building materials industry: coarse and intermediate crushing of sand and gravel, construction waste, etc., for subsequent preparation process.
6. Coal mining industry: especially suitable for crushing coal raw materials, after iron removal and impurity removal, it can directly crush raw coal. Compared with the traditional crushing equipment, it does not need to remove gangue, and the size of the crushed coal is even, which simplifies the coal selection process and reduces the production cost.
7. Electric power industry: It is used for pre-treatment crushing of coal in power plant to ensure the proper particle size of raw materials for combustion.
