Air Jet Grinder

Product Introduction

The comminution mechanism of Air Jet Grinder decides its features of wide application range and high fineness of finished product. The typical materials include: super-hard diamond, silicon carbide, metal powder, etc.; high purity requirements: ceramic pigment, medicine, biochemical, etc; low temperature requirements: medical, PVC. The machine can be inert gas protection equipment by changing parts of ordinary air to inert gas such as nitrogen and carbon dioxide gas, , which is applicable to the grade grinding and processing of inflammable, explosive and oxidized materials. There are so kinds of Air Jet Grinders and SIEHE Industry mainly researches & develops, designs and manufactures of Flat Type Air Jet Grinder, Fluidized Bed Spray Type Air Jet Grinder, and Circular Tube Type Air Jet Grinder.

Product Advantages

Good product fineness, high purity
Product granularity can be adjust between D97: 2-150 microns, good grain shape, narrow particle size distribution; The grinding process is finished by the collisions of the materials themselves, it is different from the mechanical crushing,who impact grinding the material by blade or hammer,so the equipment is wear resistance and have a high purity of the products.
Wide application
It is widely used especially in grinding of the crushing material such as high hardness, high purity,high value-added, heat sensitive,low melting, sugary and volatile material.
Environmental protection index outstanding and easy to clean
The whole system is working in closure condition with little dust, low noise, the production process is clean and environmental protection; The dismantle and clean of the equipment is convenient , the wall is smooth and without dead Angle.

Working Principle

Air Jet Grinder forms a whole set of crushing system with cyclone separator, dust collector and Induced draft fan. Compressed air, after filtration and drying, will spray into the grinding chamber in a high-speed by laval nozzle; in the intersection of strains of high pressure air flow, the material is repeated collision, shearing and crushing, under the action of the draught fan, the crushed material is rising to the classification area with the updraft movement, under the strong centrifugal force the high speed rotating of the stage turbine bring out, the material was separate according to the different fineness, the fine particles which meet the requirement of the particle size will enter into the cyclone separator and the dust remover collection by hierarchical wheel, coarse particle decreased to the crushing zone and continue to grind.
