Roller crusher crushes material by its rollers. For example, double roller crusher crushes by fixed and active rollers. Due to the special roller surface, the effect of crushing is different. Take example of double roller crusher of Great Wall Heavy Industry Company, the roller function and roller surface as follow:
Fixed roller
In order to ensure the discharging size, this roller is set to be a fixed roller, usually (or feed in metal piece) this roller stands firmly, then it will not only ensures the machine performance, but also ensures the discharging size. According to the physical properties of different materials, the roller surface is divided into overlay welding roller surface, flat roller surface, toothed roller surface;
A. Overlay welding roller surface: 45 cast steel structure, finely processed in machine tool, the surface is made of special wear-resistant alloy material with high strength, high wear resistance, it is suitable for the particle size of 3-20 mm in fine crushing operations;
B. Flat roller surface: the material is Mn13Cr2 alloy cast steel, through fine processing of machine toll, the roughness can reach below 12.5, it is suitable for the size below1-5 mm crushing operation;
C. Toothed roller surface: assembled from multiple tooth plates, tooth plate adopts the Mn13Cr2 alloy steel cast, the tooth is divided into: wolf tooth, ring tooth, straight tooth, sharp cone tooth, the tooth length is 10-100 mm (can be designed according to user’s requirements), the back of the tooth plate is made by machine tool, it is suitable for the size of 10-80 mm and less powder crushing operations;
D. Center axis: Center axis adopts high-quality chrome 40 rounds steel, processed after tempered, high strength, good toughness, bearing the weight of fixed roller and great radial force caused in working period.
Active roller
In order to protect the equipment from damaging by materials which can not be broken, this roller is designed to be active roller. In normal working situation, this roller just slightly slides. When metal pieces are fed into the crusher, roller can give way to protect the machine from damage, at the same time ensure crushing size. Forms of roller surface are divided into overlay welding roller surface, flat roller surface, a variety of toothed roller surface. Just as fixed roller described as above.
More information, even about failure, troubleshooting and maintenance, CONTRACT US, it is a pleasure to help you.
