API Grinding Mill Spiral Air Jet Mill

Widely used in chemical, pharmaceutical, cosmetics, intermediates, food and other industries.

Spiral Jet Mill Features:

1.Available particle size D50:1.5-45μm, mostly suitable for depolymerization；

2.Free of transmission parts, automatic classifying structure；

3.The jet mill is suitable for dry grinding of various materials with Moh’s hardness below 9, especially for the materials with high hardness, high purity and high added value；

4.The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So The device is durable and the purity of products is high；

5.Key parts like inner liner, classifying wheel and nozzle are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final product；

6.Grinding is in closed system, low dust and noise, clean and environmentally friendly production process；

7.PLC control system, easy operation；

8.Optional explosion-proof design, can also be upgraded to nitrogen circulation system to meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials

Spiral Jet Mill Working Principle:

MQP Spiral Jet Mill(Disc Jet Mill) works with cyclone separator, dust collector and suction fan to form a complete grinding system. Compressed air flow after filtration and drying would go into milling chamber from nozzles, and meet in the center area, where material would be impacted and ground and sheared. Milled powder would go up to the classifying chamber by the air flow from suction fan. The high-speed rotation of classifier wheel would create a strong centrifugal force to separate coarse powder and fine powder. Qualified fine powder would go through the wheel vane then into the cyclone separator or dust collector, while mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again.
