Product Information

Alpine Contraplex Pin Mills typically deliver high grinding fineness in the range 10 – 500µm, especially with brittle and crystalline materials.

Contraplex Pin Mills, C & CW

The Contraplex CW wide-chamber housing prevents coating formation, build up and thus blockages in the machine and is especially suited for moist, oily, fatty or hygroscopic products.

With the Contraplex pin mill, both pin discs are driven and rotate in opposite directions, making high relative speeds possible. Their robust drive delivers energy efficient operation.
