Gap Mill GM-D

Bauermeister Gap Mills operate successfully in a wide range of applications for grinding soft to medium-hard materials such as sugar, starch, pectin, etc. up to a hardness of approx. 4-5 Mohs. Gap Mills are mainly used in the food, chemical and mineral industry for fine and ultra-fine grinding.

The material to be ground is fed at a controlled rate into the mill, where it is accelerated towards the outside perimeter on the cover plate of the rotor. The material being ground is pre-crushed at the upper edges of the fine-grinding elements and is then forced through the grinding gap between rotor and stator by air-suction. Grinding is continued by impact along the edges of the U-shaped grinding elements while passing through the grinding gap on the outside circumference of the mill. The product/air mixture is sucked through the tangential discharge pipe at the bottom.
