Roll Crusher

Product Overview

Roll crusher is a new product designed and developed by itself with reference to the structural principle of the American Gunlake crusher. The roller crusher has a large crushing capacity. 

The motor and the reducer are connected by a distance-limited hydraulic coupling to prevent power overload and sensor overload protection, which is safe and reliable. The spacing of the gear rollers is hydraulically adjusted, and the gear roller bearings are lubricated centrally. Optimized design of tooth shape, selective crushing of tensile and shear forces, high efficiency and low consumption, and uniform granulation. 

The birth of the roll crusher completely replaced the existing 2PGC roller crusher in my country. It is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries, and is more suitable for the crushing of raw coal in large coal mines or coal preparation plants. 

Product Advantage

1. Wide range of applications, materials with compressive strength less than 250Mpa can be double-rolled crusher, such as: iron ore, quartz stone, potassium (sodium) feldspar, limestone, river pebble, metal silicon, barite, basalt , granite, steel slag, cement clinker, construction waste (concrete), shale, quicklime, coal, coke, clay, bentonite, chemical raw materials, etc. 

2. Roll crusher has simple structure, small occupied space and convenient operation and maintenance. The interior is equipped with a dust-proof plate, which has good sealing performance and avoids the splashing of small materials after crushing, with less dust, and the working environment is greatly improved. The abrasive roll body is re-optimized design, and the equipment does not need to be replaced for life. 

3. With compact structure, light weight and small volume, compared with the grinding series with the same production capacity, the roll crusher can significantly save investment. 

4. Simple structure, small footprint, convenient operation and maintenance. 

5. The interior is equipped with a dust-proof plate, which has good sealing performance and avoids the splashing of small materials after crushing, with less dust and low working noise. 

Working Principle

Roll crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. Roll crushers are classified according to their specifications. The adjustment of the discharge granularity is that a wedge or gasket adjustment device is installed between the two rollers. The top of the wedge device is equipped with an adjustment bolt. 

When the adjustment bolt pulls the wedge up, the wedge pushes the movable roller away from the fixed wheel. , that is, the gap between the two rollers becomes larger, and the discharge particle size becomes larger. When the wedge goes down, the gap between the two rollers of the movable roller becomes smaller under the action of the compression spring, and the discharge particle size becomes smaller. 

The gasket device adjusts the size of the discharge particle by increasing or decreasing the number or thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger, and when the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller.
