Turbofiner Type PLM


Production of fine powders with a narrow particle size distribution from soft to medium hard and heat sensitive materials.

Method of Operation

Material is fed into the grinding chamber with a screw feeder and is pulverized inside the grinding chamber in a high activity whirl created between the stationary and rotating grinding elements of the mill.

Due to the high air volume particles are impacted against each other and get micronized. Even heat sensitive materials stay cool during the grinding process. An internal classifier rejects coarse material, which is fed back into the grinding chamber, where as the fine product is pneumatically conveyed into a filter bag.

Advantages & Features

  • The columnar construction of the Turbofiner with clamshell type hinged stator in combination with the cantilevered bearing allows easier exchange of the wear parts and of the complete rotor
  • The grinding chamber is well accessible for cleaning and maintenance
  • Pressure-proof designs up to 10 bar are available
  • Cool, gentle fine and finest grinding
  • High throughput capacity
  • Wide variety of applications
  • Grinding and drying in one single step
  • Easy to clean

Excellent for pulverizing medium hard to soft materials
