Detachable roller of high pressure roller mill

Abstract

A detachable roller of a high pressure roller mill relates to the technical field of structures of the detachable roller of the high pressure roller mill. The detachable roller comprises a main shaft, a roller rack and a wear resistant roller skin, the wear resistant roller skin is obtained by combining a plurality of small roller skins, the wear resistant roller skin is uniformly distributed, the small roller skins have a same size, and the small roller skins are detachably connected with the roller rack through bolts respectively. The wear resistant roller skin is divided into the plurality of independent and detachable small roller skins, so the wear resistant roller skin can be conveniently maintained; and the middle roller rack and the main shaft can be reused multiple times, so the service life of the roller is effectively prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to the structural technical field of a detachable roller of a high-pressure roller mill. Background technique [0002] Usually, the high-pressure roller mill is used in the ultra-fine particle crushing industry. It mainly uses the high pressure of hydraulic energy storage to squeeze and crush the material through the relative rotation of the driving and driven rollers to complete the crushing process of the material. The rollers of traditional roller mills are manufactured by stacking wear-resistant welding rods or inlaid casting nails on the surface of the whole rotor. After the surface of this kind of roller is worn and damaged, it needs to be replaced together with the internal rotor as a whole. Replacing the whole roller not only affects the production efficiency, but also increases the production efficiency. Lower production costs, low metal utilization, resulting in a sharp increase in production costs. Contents of the inv...
