Pin Mill Type PST & PPST

 

 

Fine and ultra fine grinding of soft to medium hard, brittle, crystalline, moist and fatty materials.

Method of Operation

Pin Mills, type PST are used for fine to finest grinding of dry, brittle, or hard to grind materials to a fineness of d50=5 micron.

Material is fed centrically by a dosing mechanism and magnetic separator. Grinding is done by impact and whirling between the concentrically mounted pin rows of the rotating and the stationary discs. Particle size is determined by the speed, number and type of pins.

PIN Mills, type PPST are high-speed, counter-rotating machines, and they work without a screen. Pin rows, concentrically fixed on rotor and stator discs micronize the particles.

Special designs for cryogenic applications are available.

Advantages & Features

  • Easy access to the grinding chamber due to large door
  • Very fine powders due to high speed
  • Special designs for cryogenic grinding available

Also utilized for deagglomeration, mixing and homogenizing chemical and pharmaceutical products as well as for cryogenic pulverizing applications.

  • Plastics
  • Food Products
  • Pharmaceutical products
  • Chemical Products
