What are the solutions for the hydrocyclone with fast wear

Hydrocyclone is mainly used for classification, sorting, concentration and desliming in mineral processing industry. When the hydrocyclone is used as classification equipment, it is mainly used to form a grinding classification system with the mill; when used as desliming equipment, it can be used for desliming in the re-election plant; when used as concentration and dewatering equipment, it can be used to concentrate the ore dressing tailings and send them to fill the underground mining pits.

Water media cyclone is also known as autogenous media cyclone. It is the formation of media sorting with water and fine particles in the feed, without the need for additional high-density media, due to the actual sorting density and media density difference is large, so the role of particle size classification in the water media cyclone is more obvious. In order to obtain better sorting accuracy by density, the cyclone design is modified and the particle size range of the incoming coal is limited to be not too wide.

As the bottom flow pipe and overflow pipe are directly connected with the atmosphere, the two-phase flow entering the cyclone moves with strong spiral vortex. When the tangential velocity increases to the critical velocity, resistance is generated at each outlet of the cyclone, forming an internal rotating flow field and causing negative axial pressure, air enters the cyclone from the overflow pipe and bottom flow pipe, and gradually develops into a through air column under the joint action of negative axial pressure drive and fluid convection transmission.

In the industry of mineral particles according to the density of sorting cyclone can be divided into two categories, one is heavy media hydrocyclone, the other is water media cyclone. Hydrocyclone can be used for ball mill coarse sand and overflow classification, as well as pre-classification before the grinding operation, the process index is roughly the same as the mechanical classifier, and can basically replace the classifier work.

Hydrocyclone is composed of several parts, such as cylinder, cone, feed body, overflow pipe and flow port. It has the advantages of simple structure, convenient operation, large production capacity, high classification efficiency, small footprint, no transmission parts and easy to realize automatic control. With the increasing diversification of cyclone structure and type, it is now widely used in mining, coal processing, chemical, construction and other industries.

The so-called cyclone classification, that is, according to certain physical and chemical properties of the particles, the particles are selected and separated. So far, hydrocyclones can classify particles according to their density, shape, surface hydrophobicity and magnetic properties. The classification of solid phase particles by density with hydrocyclones is widely used in the mineral processing industry.
