Roll crusher is also named double-roll crusher,roll-type crusher.It is

usually used to crush the raw materials such as coal , coal gangue,

coke , limestone, sulfur ore, phosphate rock and etc, which are

usually crushed in middle or fine size by the way of roll extrusion .Roll

crusher is widely used in the fields of ore dressing, chemical, cement,

refractories, grinding materials, building materials, etc., and it has

more excellent performance than the general machinery in crushing

ofof building materials, particularly in crushing materials like gangue

stone and mung bean stone.

1.Roll crusher mainly consists of rollers, roller support bearings, pressed and

regulation devices, drives, and etc.

2.Adjusting2.Adjusting of output granularity: there is a wedge or gasket adjusting device

between the two rollers. Wedge adjusting device:there is a adjusting bolt on the

top of the Wedge device. When the wedge is pulled up by adjusting bolt, the wedge

pushes the movable roller away from the fixed roller. That is to say, when the gap of

the two rollers becomes wide, output granularity shall become larger accordingly.

When the wedge falls down, the gap of the two rollers becomes small under

pressure of the spring, output granularity becomes small. Gasket adjusting devices:

itit is used to adjust output granularity by means of increasing or decreasing

numbers or thickness of the gasket. When adding gaskets,

the gap of the two rollers becomes wide,and

output granularity becomes large, when

decreasing gasket, gap of the two rollers

becomes small, and output shall be fine

accordingly.

3.There3.There are two motors which drive the rollers

by V-belt. Both rollers rotate in opposite

direction.

4.When materials are being crushed, the feed

material are in put from the inlet and crushed by
