The structure of the hydrocyclone is relatively simple, mainly composed of a conical shell, a cylindrical shell, an ore feeding nozzle, a grit discharge outlet, an overflow pipe, and an overflow discharge nozzle. The wear problem of the hydrocyclone is the most serious wear of the sand settling port and the mine feeding port. The wear of the grit outlet increases the area of the discharge port, increases the grit output, reduces the concentration, and seriously affects the separation efficiency of the hydrocyclone.
Solution:
Aiming at the wear and tear problem of the grit chamber and the ore inlet, the method of making the wearable parts such as the grit chamber and the ore inlet into replaceable parts can be adopted. It is also possible to prepare a wear-resistant protective layer on the inner wall of the grit chamber as a whole. In addition, the grit chamber of the hydrocyclone can be made into a variable structure. The optimization of the feeding method of the hydrocyclone is also beneficial to alleviate the wear problem of the hydrocyclone. For example, in Huazhan XC11 hydrocyclone, the feeding port adopts the involute direction to feed the material, which is conducive to increasing the centrifugal force of the material, which not only improves the classification effect of the hydrocyclone, but also greatly reduces the burden on the feed box. wear and tear.
