have a broad application in the processing technology and are used for gentle crushing of soft to medium-hard bulk materials.

 

The feed material is broken between the counter-rotating rolls and crushed by pressure and shearing stress. Throughput capacity is up to 2,000 t/h, crushing ratio is approx. 1:6.

Feed materials: limestone, gypsum, coal, coke, different types of ore.

 

Sand, Coal, building materials, stone factory, chemeical industry, and so on, can crush the middle - hardness ore and rocks.

 

Double roll crusher Working Principle:

The discharging size is adjustable. Between the two rollers, there are wedge-shape or gasket adjusting device. There are adjusting bolts in the top of the wedge device. When the adjusting bolts lift the wedge upwards, the wedge pushes movable roller away from the fixed roller, so the gap between two rollers becomes big and the discharging size is big. When the wedge moves downwards, gap between two rollers becomes small under the influence of pressure spring. Discharging granularity is small accordingly.The gasket device adjusts the discharging size by changing the thickness and quantities of gaskets. The gap between two rollers becomes large when the quantities of gaskets increase, and the gap becomes small when the quantities of gaskets reduce. Drive mechanism adopts two motors which drive triangle belt to drive the rollers to rotate in the opposite directions. When double roller crusher works, materials fall into the gap between rollers through feeding hole. They are compacted and crushed, and then are discharged.
