How To Solve The Partial Wear of The Hydrocyclone?

Hydrocyclone is a kind of equipment that uses centrifugal force to carry out classification and separation. It is often used in the mineral processing industry for the classification of coarse and fine-grained minerals, as well as the dehydration and concentration of pulp. However, the hydrocyclone is prone to wear during use, especially the grit port and the mine feed port. How to solve the partial wear of the hydrocyclone?

1. Abrasion of the wall surface of the hydrocyclone

During the operation of the hydrocyclone, the mineral particles deviate from the flow direction of the flow field under the action of centrifugal force and make a strong rotational movement. Under the violent scouring of the mineral slurry, the wall surface of the hydrocyclone was impacted and rubbed by the mineral particles, causing serious abrasion problems.

Solution

The commonly used method is to line the inside of the cyclone with rubber, cast iron or coating with wear-resistant materials. Or the entire cyclone is made of wear-resistant rubber to increase the wear resistance of the hydrocyclone wall.

2. Wear near the feed inlet and grit nozzle of the hydrocyclone

The wear problem of the hydrocyclone is the most serious wear of the grit port and the ore port. The wear of the grit port increases the area of the discharge port, increases the grit output and reduces the concentration, which seriously affects the separation efficiency of the hydrocyclone.

Solution

Aiming at the problem of the wear of the grit port and the ore port, the method of making the easily worn parts such as the grit port and the ore port into replaceable parts can be used. The grit port of the hydrocyclone can also be made into a variable structure. The optimization of the feeding method of the hydrocyclone is also conducive to alleviating the wear problem of the hydrocyclone.

3. Serious wear caused by unreasonable structure of hydrocyclone

Although the structure of the hydrocyclone is relatively simple, its installation and operation are relatively easy, but if the manufacture or installation of the hydrocyclone is of poor quality or the structure is unreasonable, it will easily cause severe local wear.

Solution

The installation method of the cyclone is vertical or inclined. In order to avoid serious wear and tear of the hydrocyclone due to improper installation, when selecting and purchasing a hydrocyclone, it is necessary to choose a beneficiation equipment manufacturer with strong equipment manufacturing capabilities, installation and service capabilities.
