Spiral Jet Mill

MQP disc jet mill, also known as spiral jet mill, the basic principle is: use the negative pressure generated by compressed air to suck the material in the hopper into the flat grinding chamber; The high-speed airflow (sonic speed or even supersonic speed) collides and crushes each other, and the materials that reach a certain particle size will approach the center of the grinding chamber due to the reduction of centripetal force, and will be discharged from the grinding chamber with the flow of airflow, and then enter the cyclone and dust collector.

Working principle of Spiral Jet Mill

Disc type(Ultrasonic/Pancake)Jet Mill. The Operating Principle: Driven by compressed air through feeding injectors, raw material is accelerated to ultrasonic speed and injected into a milling chamber in the tangential direction, collided, and ground into particles. The particle size can be controlled by adjusting the longitudinal depth, milling pressure, and material feeding speed. Disc-type Jet Mill does a good performance to gummy materials.

Technical Advantages of Spiral Jet Mill

  • Without any rotating parts, CNC precision machining, no welding seam, easy to clean.
  • No medium grinding, the grinding chamber can be protected by stainless steel and wear-resistant ceramics to ensure product purity.
  • Low temperature grinding, especially suitable for grinding heat-sensitive, low-melting, sugar-containing and volatile materials.
  • The grinding process is extremely short, the crushing efficiency is high, and the over-grinding is less.
  • Suitable for grinding, dispersing and depolymerizing, and particle shaping of materials with various hardness.
  • The whole system is closed, without dust, low noise and easy to operate.
