Operating principle
In DM 200 supplied from the product in the sealed compartment to the grinding dust through the filling hopper and is conducted to the center of two milling discs arranged vertically. A movable grinding disc rotates against a stationary disk and enters the product to be ground. The compression force and the shearing stress cause the desired grinding effect. The gradual provision of teeth grinding disk are initially a first product breakage and transported by centrifugal forces to the outer area of ​​the discs where fine grinding takes place. The ground product out of the grinding gap and is collected in a collecting container. The width of the gap between the grinding discs is continuously adjustable. It can be adjusted from 0.1 mm to 30 mm during operation with a scale and is controlled by an additional window.
