Spiral Jet Mill

On-line cleaning (CIP) and on-line sterilization（SIP）design is optional
  • 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.
  • Constant temperature or low temperature, medium-free grinding,especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature.
  • Available product size D50: 2~100μm.
  • No rotating parts, easy to disassemble and clean.
  • The whole steel plate of the main body is processed by CNC without welding seam.
  • On-line cleaning (CIP) and on-line sterilization（SIP）design is optional.

Working Principle

Compressed gas is used to pass the feeder ejector to bring the ground raw materials into the grinding chamber, and driven by the high-speed airflow from multiple nozzles, it is sprayed on the grinding wall in a tangential manner to achieve the effect of friction grinding. By adjusting the longitudinal depth of the grinding chamber, adjusting the grinding pressure or feeding speed, the fineness of grinding can be controlled. Compared with the fluidized bed jet mill, the controllability of the pulverization fineness is less.
