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.
LHB airflow classification process flow chart
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.
We can supply big range of such stainless steel Casting Parts, including investment casting and Sand Casting
Sand Casting method (Sand Casting)
Using Sand as Mold material, according to the different components of Sand can be subdivided into wet Sand casting method of Green Sand Mold), surface Dry Sand casting method (Dry Sand Mold), and so on, but not all are available in the casting.
Advantage is lower cost, because the sand mold use reusable;
Lost wax Casting, Investment Casting
This method can be as the outer membrane casting method and the solid casting method.
To copy wax casting items required first, and then into the pool with ceramic and stay dry, make with wax replica is covered a layer of ceramic outer membrane, repeat steps until enough to support outer membrane casting process (about 1/4 inch to 1/8 inch), then the wax melting mould, and out of mold. Then mold need to high temperature for many times, enhance behind the hardness could be used in the casting.
This method has good accuracy, can be used as a high melting point metal, such as titanium casting.
