The structure of the roller crusher:
The crushing rolls consist of the roller bodies, complemented with crushing rings or crushing shells. The rolls are secured either with anchor bolts and end disks, or bolted with screws. In order to facilitate maintenance, the crushing roll shafts are arranged in heavy-duty cast steel housings with lubricated, amply dimensioned spherical roller bearings. Materials used are of highly wear-resistant specially cast alloys in order to achieve long lifetimes of parts. China Double roller crusher for coal, chemical, slag, clay, limestone, double roll coal crusher
The design of the roller crusher is for customers' benefits:
1.With the advanced hydraulic control system, users can adjust the pressure according to the material hardness, so that can press and pulverize the materials absolutely.
2.With sensor, the machine can load relief when overload, so that to protect the machine.
3.The advanced hard faced technology improves the roller covers' life.
4.Good performance, low cost in operation and easily maintenance.
Double Roller Crusher Operating Principle
This double roller crusher adopts two motors, which take two rollers to rotate reversely by the decelerator. When the materials drop on the rollers through the feeding hole, under the friction of the rollers, they are dragged between the rollers, grinded by the rollers and crushing, the crushed materials are pushed out by the rollers.
Double Roller Crusher Features
1. The double roller crusher structure is simple and compact, the noise is low, and the efficiency is high.
2. The installation is flexible, basically needs no foundation.
3. The rollers' surface adopts anti-friction welding rod or exchangeable dental plate, the maintenance is simple.
4. Self-preservation ability is strong, high hardness materials (such as metal block) won't break the equipment's parts when they enter the crushing cavity.
5. The discharging granularity is adjustable; the minimum can reach 2-10 mm.
