Air Jet Pulverizer
The comminution mechanism that our Air Jet Grinder mainly suitable decide the features of wide application range, 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. By change the air part ordinary air to inert gas such as nitrogen and carbon dioxide gas, the machine can be inert gas protection equipment, which is applicable to the grade grinding and processing of inflammable, explosive and oxidized materials. There are kinds of Air Jet Grinder, Siehe Industry mainly absorb in research, develop, design and manufacture of Flat Type Air Jet Grinder, Fluidized Bed Spray Type Air Jet Grinder, and Circular Tube Type Air Jet Grinder.
Product Overview
| Materials Hardness | Mohs hardness 9 |
| Production Capacity | 5-6,000L |
| Application Industry | Suitable for grinding of materials such as chemical, mineral, metallurgy, abrasive, ceramics, refractory matter, medicine, pesticide, foodstuff, health product, New materials, etc.. (For more application industry, please click “Free Consultation” ) |
| Applicable Materials | Materials shall be with hardness less than mohs hardness 9 and high requirement of grinding fineness such as diamond, silicon carbide, medal powder, ceramic stains, PVC, etc. |
Working Principle
Air Jet Grinder form a whole set of crushing system with cyclone separator, dust collector, 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.
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 safe
The whole system is closed grinding, 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.
