Impact mill (AIR CLASSIFYING MILL)

Mills Powder Engineering - Impact Mill Manufacturer

Widely applied to chemical new material, additive, non-metallic mineral, food, medicine, new energy, agricultural chemicals, coatings, dye, electronic materials, flame retardants, rubber additives, ceramic, calcined kaolin, light calcium carbonate, aluminum hydroxide, aluminum oxide, mica, graphite, AC foaming agent, petroleum coke, and flaky, acicular and fibrous materials.

Special application: Connected with air classifier to compose production line for protein separation and extraction from agricultural products, for example, pea protein, wheat protein.

Working Principle:

Materials are fed into the grinding chamber by feeding system, they are impacted, sheared and ground by high speed rotary hammers and tooth plate. The ground materials enter into the classifying zone with airflow, the coarse and fine powder are separated through the classifying wheel adjusted by the frequency conversion, qualified powder is collected by the cyclone separator and dust collector, the coarse powder continues to be ground.

Feature:

1. Integration of grinding and classifying, thus avoid over grinding.
2. Speed of classifying wheel is adjustable to obtain ideal particle.
3. Narrow particle size distribution, fineness d97=2～100 micron is adjustable.
4. Inner temperature is reduced by airflow, and grinding chamber is used water cooling jacket for cooling, suitable for heat-sensitive materials.
5. Negative pressure work condition, no dust pollution.
6. Grinder is equipped with slag discharge device, which can automatically discharge the hard and impurity materials.
7. Less wearing parts and easy maintenance.
8. Can be connected with multi-stage classifiers to obtain products with multiple sizes at one time.
