AIR JET MILL - EMCO PSI 12
The EMCO PSI – 12 works independently with the process at a constant temperature. The powder is fed at below sonic speeds into the flat cylindrical milling chamber tangentially through a venturi. The system uses compressed air. Once the particles are inside the milling chamber they are accelerated by a series of jets around the perimeter to supersonic speed, in a spiral movement. The micronising effect occurs when the slower incoming particles and the faster particles in the spiral path collide. While centrifugal force retains the larger particles at the periphery of the milling chamber, the smaller particles exit with the exhaust from the center of the chamber.

The Particles Size Distribution is controlled by adjusting the 3 main parameters



  • Milling Pressure – the energy used to micronize the product, increasing pressure, increases the micronization effect.

  • Feed Pressure – The energy used to introduce the product into the milling chamber.

  • Feed Rate – the concentration of product fed into the milling chamber, the greater the feed rate, the less the micronization



Effect, because particles must have space to achieve proper acceleration and collision.
