Performance characteristics and development trend of air classifier

The air classifier is a kind of equipment that classifies materials by the centrifugal force of the impeller rotation and the traction force generated by the air flow. It has the characteristics of high classification accuracy, energy saving, high efficiency and low production cost, and is in quartz , feldspar , mica and kaolin. magnesium oxide fractionation purification process has been widely used.

The classification of the airflow is based on the centrifugal force, gravity, inertial force, etc. of the particles of different particle sizes in the gas (usually using air), and different motion trajectories are generated, thereby realizing the classification of particles of different particle sizes. The air classifier can be divided into a static classifier and a dynamic classifier according to whether it has moving parts.

1. Classification and performance characteristics of air classifier

2. Development direction of air classifier

(1) Large and refined

With the continuous expansion of the ultra-fine powder market and the expansion of production scale, the demand for large-scale superfine pulverizing and fine grading equipment will continue to increase in the processing of ultra-fine powder. The use of large-scale equipment can reduce the energy consumption per unit of product and simplify Process and reduce floor space, thereby reducing equipment investment and production costs per unit of product.

(2) The vortex air classifier gradually dominates the market

The vortex air classifier is widely used in construction, mineral processing, fine chemicals, special ceramics and other industrial fields due to its simple structure, adjustable graded particle size and wide adaptability.

(3) Automation control

Industrial control automation technology is developing in the direction of intelligence, network and integration. The automatic control of airflow classification improves the production efficiency, reduces the labor intensity of workers, improves the overall automation level of the powder processing industry and the core competitiveness of enterprises. It is very important.
