1. The material of the rollers is wear-resistingchromium molybdenum copper alloy, and the rollers are heat treated for manytimes, so its service life is 2000-8000 hours(according to the hardness of theraw material).


2.When the material is too hard or there is unbreakable materials, the activeroller will draw back automatically by the force of the spring or hydraulicsystem to protect the machine from being damaged.


3.The gap between the rollers is adjustable, so that the output size andcapacity will be changed accordingly.


4. This crusher uses the best bearing produced by cooperation of Wazhou Groupand SKF, the service life of the bearing is more than 20000 hours. The innerand outside of the bearing are both double sealed, so the lubrication oil canbe added in a long period.


5. This crusher uses no power distributor, the materials will be evenlydistributed into the crusher, to ensure good output size and protect the rollersurface from being worn down unevenly.


6. This crusher is equipped with motorless scraper. When the raw material hashigh moisture content, it can avoid to affect the output size and avoidsticking the roller or blocking the machine.


7. It runs in different speed, the rollers do cleaning for each other to avoidthe raw materials caking.


8. This crusher features reliable operation, low failure rate, low noise andlow maintenance cost.

roller crusher

Roller Crusher is widely used for fine orsuperfine crushing in the industries of mining, construction materials,metallurgy, chemical industries and so on. It can crush all kinds of materialsunder middle hardness, such as ore, rock, coke, coal, clinker, ceramic rawmaterials, slag, refractory materials, chemical materials and so on. Forexample, to make silica sand from quartz or silica stone; crush iron ore intofine powder for iron ore beneficiation; to make machine-made sand from cobblestoneor building waste; to do fine crushing of potash feldspar and soda feldspar forceramic industry; to do fine crushing of limestone for desulfurization in heatand electricity industry; to do precrushing of the cement raw materials beforefeeding into the mill etc.

Double Roller Crusher
When it works, the raw material is fed in and fall into the V type crushingcavity between the two crushing rollers and crushed into qualified sizes by theextruding and cutting force of the two counter-rotating rollers, and thendischarged from the outlet.


Three Roller Crusher
The three rollers adopt the structure of stagger arrangement and forms twocrushing cavities. When the crusher works, the materials are first fed into theV type crushing cavity of the two upper rollers, and being crushed by theextruding and cutting force of the two counter-rotating rollers,and then fall into the secondcrushing cavity to be crushed again. After being crushed for two times, thematerials are discharged from the outlet.


Four Roller Crusher
a)Four Rollers Two Crushing Cavities
The four rollers are divided into two parallel groups(upper & lower),andforms two separate crushing cavities. When the crusher works, the materials arefed into the V type crushing cavity of the two upper rollers, and being crushedby the extruding and cutting force of the two counter-rotating rollers. Then itfalls into the crushing cavity of the two lower rollers and being crushedagain. After being crushed for two times, the materials are discharged from theoutlet.
b)Four Rollers Three Crushing Cavities
The four rollers adopt the structure of stagger arrangement and forms threecrushing cavities. When the crusher works, the materials are first fed into theV type crushing cavity of the two upper rollers, and being crushed by theextruding and cutting force of the two counter-rotating rollers,and then fall into the second andthird crushing cavity to be crushed again and again. After being crushed forthree times, the materials are discharged from the outlet
