We manufacture the following grinding tools for our own mills and those of other manufacturers:
beaters, crushing blades, crushing rotors, fan crushers, grinding tracks, grinding wheels, mill pins, pin disks, pendulum beaters, pins and shafts for stirred mills, plate beaters, shafts, sieves, sifter wheels, tooth lamellas, turbo-rotors, wear rings,...

We can also supply these grinding tools in improved quality:
By selecting the ideal materials and using special hardening techniques, wear and tear is considerably reduced. We can also give stainless steel a wear-resistant hardened surface. For cold milling we supply tools made from a material, which is resistant to subzero temperatures and can also be hardened.

Fluted Mill Pins for Disc Mills
Fluted mill pins can be used in existing disc mills instead of the customary round pins. Instead of the circular crosssection, the extension from the disc of this type of pin is fluted lengthwise.
The surface and thus the area of contact for the particles is greater. The particles bounce against the pins more often and more effectively thus increasing the efficiency factor of the mill.

  • Finer material to be ground (smaller particle size)
  • Impact crushing combined with crack effect

Application Examples:
  • All material to be ground that requires fine grinding.
  • Excellent comminution results during cold comminution, i. e. with viscoplastic products that require embrittling with liquid nitrogen, for example Plastic and rubber recycling.
  • Fine spice powder, ...

Hardened tooth lamellas

The solution to this problem is the use of our patented hardened tooth lamellas:

Each tooth consists of one lamella, whose edges are hardened and ground until they are razor-sharp. In order to balance the radius for the parts with rotational symmetry, there is a diagonal spacer lamella between every two tooth lamellas. Because they are braced in pairs and therefore not in danger of breaking, the tooth lamellas can be manufactured from wear-resistant hardened tool steel. This preserves the sharp edge of the tooth lamella for a very long time. If the tooth lamellas are worn out after a long period of use (1-2 years are quite common depending on the product) they can be sent to us to be replaced. The spacer lamellas can be re-used.
