Product application of Double roll crusher:

Roller crusher is mainly applied in cement, metallurgy, chemical, electric power, coal and other industries for crushing various materials of medium hardness like limestone, slag, coke, coal and other materials. According to the numbers of the roller, it is divided into single roller crusher, double rollers crusher and multi-rollers crusher. It has simple structure, less phenomenon of over-crushing, and reliable operation.

It mainly consists of frame, rotary device, crushing roller, adjustment device and spring safety device, etc.

The double-roller crusher is widely used to process all materials with compression strength less than ***0kg/cm2 such as cement, metallurgy, chemical industry, building materials and fireproofing, etc.

Features and Benefits double roll crusher:

1.Simple structure, reliable operation;

2.Low cost and less over-crushing phenomenon;

3.Adjustable discharging size, and high economic benefits,

The crusher is a new type roller crusher; the two rollers rotate slowly with a low cost and generate high extrusion force. Movable roller may spring quickly back when metal entered. This kind of crusher is with low abrasion, low yearly maintenance expense and long service life. Also the rollers are made of high strength casting steel, which are unnecessary to be changed.

Product principle of Double roll crusher:

The double roller crusher is mainly composed of rollers, high manganese steel roller sheet, steady bearing of roller, depress device and regulating device and driving device. Adjustment of discharge particle size: the clearance between the two rollers can be adjusted to change the sizes of final products. There is a wedge or gasket regulating device between two rollers, and an adjustable bolt on the top of wedge. Wedge block will drive the movable roller leave the fixed one when it is pulled up by adjustable bolt, and the gap between rollers is bigger and also the discharge particle size become larger; when wedge block moved down, the movable roller may close the fixed roller under the force of pressure spring and the discharge particle size become smaller. As for gasket device, the discharge particle size may be adjusted according to the number of gaskets. The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotate inward simultaneously. The materials are extruded, crushed and grounds, then the end products come out from the bottom of this crusher.
