A rotary - vortex mill PBM
A rotary - vortex mill type PBM intended for fine grinding, mixing and mechanical activation of solids. The equipment allows to grind the material with a hardness of 6 Mohs give powders having a particle size of 5 microns or less. Mills are equipped with a built - in aerodynamic classifier. This allows you to output a given homogeneous powder dispersion.
The resulting fine ground material may be used in various fields of production:
- construction industry (building materials);
- chemical and paint industry;
- food industry.
Mill grinding of the following materials:
- mineral (chalk, talc, gypsum, borax, carbon, mica, graphite, slag, fly ash, cement, etc. );
- polymer (PVC, for rotomoulding polyethylene, Teflon, polypropylene, rubber);
- organic (wood flour for the KDP, grass meal, meal, walnut shells, husks);
- food powders (powder sugar, rice, soybean, cocoa, algae, bagasse, cherries, pepper, spices, etc. . . ).
The arrangement of mill selected according to the type of material and the type of its destruction. The arrangement of the rotor - vortex mill may be configured with a forced air flow through the grinding chamber or without air duct (see. Table). Passing air cools the material and the grinding chamber, and conveys the crushed material participates in the centrifugal classification of the material.

The grinding chamber rotary type has the following features:
- the chamber structure has elements each particle providing reception series of punches, which leads to the guaranteed pulverized material already at moderate rotor speeds.
- Rotor with impact elements made of wear - resistant steel. A large number of impact elements and rotor cage increases their service life.
- The rotor is balanced in the manufacture of their own supports, vibroaktivnosti mill GOST ISO10816 - 2002. Such measures reduce noise and vibration during operation of the mill and increase bearing life, provide long and safe operation of the equipment.
- At the outlet of the grinding chamber arranged classification of the crushed particles. Classification of particles during grinding to reduce the spread of particle size of the finished product and increases the efficiency of the grinding process due to the fact that particles of the required size continuously discharged from the grinding chamber does not dissipate energy and drive to overgrinding and friction between them.
