PG Roller Crusher

Usage and Application
PG roller crusher is widely used for fine or superfine crushing in the industries of mining, construction materials, metallurgy, chemical industries and so on. It could crush all kinds of materials under medium hardness, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, chemical materials and so on.

Features
1. Material of the rollers is wear-resisting chromium molybdenum copper alloy, the rollers are heat treated for many times, so its service life is times of the common high manganese steel;
2. When the material is too hard or there are unbreakable materials, the active roller will draw back automatically by the force of spring or hydraulic system to protect the machine from being damaged;
3. The gap between the rollers is adjustable, so the output size and capacity would be changed accordingly;
4. This crusher adopts unpowered distributor, the materials will be evenly distributed into the crusher to ensure good output size and protect the roller surface from being worn down unevenly.
5. This crusher is equipped with unpowered scraper. When the raw material has high moisture content, it can avoid to affect the output size and avoid sticking the roller or blocking the machine.
6. It runs in different speed, the rollers do cleaning for each other to avoid the raw material caking.
7. This crusher has features of reliable operation, low failure rate, low noise and low maintenance cost.

When double roller crusher works, the raw materials are 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, then discharged from the outlet.
Four roller crusher adopts the structural form of vertical arrangement for upper and lower crushing rollers, which forms two independent crushing chambers. Materials are crushed by upper rollers, then fall down to lower rollers to be crushed again, finally discharged via discharging outlet.
