Comprehensive introduction of roll crusher

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 17, 2012 -- Roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks in mine selection, chemicals,Jaw crushers cement and building materials industrial production. The roller crusher has widely application in the industries of mining, building materials, chemical industry, metallurgy, etc. The roller crusher can crush materials with middle hardness or less than middle hardness into secondary or fine granularity,Hydraulic cone crusher such as crushing mineral, rocks, coke, coal, slag,Rock cone crusher scoria, and fire-proof material etc.
Main applications:

Mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production.
Working Principle:

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 rotates inward simultaneously. The materials are extruded,Jaw crushers crushed and ground, then the end products comes out from the bottom of this crusher. There are adjusting devices (wedge or gasket) between two rolls, with adjusting bolts fixed on the top of wedge.Jaw crusher supplier When adjusting bolts hang up wedge, the wedge will drive moving roll away from fixed roll. Roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.China dryer The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

This series of crusher is used for crushing of ores and rocks,Hammer crusher the advantages are: reliable structure, high efficiency, easy-to-adjust and economical. The safety spring system is the overload protection device, which makes foreign material goes through the machine without bring any hurt to it. The sealing modes are oil and water, which segregate the stone powder and lubricating system. The crushing chamber is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.
