Working Principle

When double roll crusher works, the raw material is fed in and fall into the V type crushing cavity between the two crushing rollers and crushed into qualified sizes by the extruding and cutting force of the two counter-rotating rollers, and then discharged from roller crusher outlet.

Features

1.The material of the rollers is wear-resisting chromium molybdenum copper alloy, and the rollers are heat treated for many times, so its service life is 2000-8000 hours(according to the hardness of the raw material).
2.When the material is too hard or there is unbreakable materials, the active roller will draw back automatically by the force of the spring or hydraulic system to protect the machine from being damaged.
3.The gap between the rollers is adjustable, so that the output size and capacity will be changed accordingly.
4. This crusher uses the best bearing produced by cooperation of Wazhou Group and SKF, the service life of the bearing is more than 20000 hours. The inner and outside of the bearing are both double sealed, so the lubrication oil can be added in a long period.
