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
