1. Introduction of Roll Crusher:
- The roll crusher(roller crusher) can grind hard, medium hard ore
and rock in mine, chemical, cement, refractory, construction
- Roll crusher has better effect than common machine in construction
material industry.Roll crusher can also be called roller crusher.
- It is composed of two rollers rotating with opposite direction.
- Materials go into the space between the two rollers from the upper
part and then will be squeezed and crushed by the two rollers, and
crushed materials will be discharged from the bottom of the
- The space between the two crushing rollers can be flexibly adjusted
to produce products with different fineness.
2. Main technical parameters of Double Roll Crusher:
|Roller Diameter (mm)||400||610||450||500|
|Roller Length (mm)||250||400||500||750|
|Max. Inlet Size (mm)||≤25||≤85||≤100-200||≤300-600|
|Discharge Granulator (mm)||2--8||10--30||25-100||50-125|
|Roller Number (PCs)||2||2||2||2|
|Roller Speed (r/min)||180||75||64||50|
3. The working principle of Double Roll Crusher:
Adjustment of discharging granularity: There is wedge or gasket
adjustment device between two rollers of roller crusher. The
adjusting screw bolts are fixed on the head of wedge head. When the
adjusting screw bolts pull the wedge upwards, the wedge makes the
roller be apart from fixed pulley. The gap between the two rollers
becomes bigger and then the discharging granularity becomes bigger.
When the wedge goes downwards, the gap of the two wedges becomes
smaller and then the discharging granularity becomes smaller.
Gasket device adjusts the granularity by decreasing and increasing
the gasket numbers or thickness. When the gasket number increases
,the gap of two rollers and granularity become bigger, on the other
hand ,the gap and granulariyt become smaller.
- It's available for ore dressing, chemical, cement, refractories,
abrasive, building materials industries;
- Roll crusher has the more excellent effect than general stave
- Finely crushing all kinds of ore and rock below the high, medium
hardness,which can make the minimum grain size below 100 mesh;
- Roller crusher is stable operation, easy maintenance, low cost,
output size adjustable.
