Cyclone grinding mill UM 150

ultrafinefor sample preparation

Multi-purpose mill The multi-purpose mill UM 150 is used for finely grinding – up to a hardness of approx. 6 on the Mohs scale – dry, brittle, medium-hard materials < 15 mm fed in doses. The grinding effect is based on impact and shear force, caused between the rapidly turning rotor and toothed grinding path. Material ground until passing slotted screen. Prevents overgrinding. Ground material separated by cyclone into 500 cm³ bottle or optional pipe for larger vessel. To inspect and clean the machine, its housing cover can be opened, so that the grinding chamber and the cyclone can be fully examined. The damper-supported cover is monitored for the operator’s safety, and when it is opened causes an instantaneous emergency stop by the brake motor. When the cover is opened, the slotted filter inserts, that are decisive for the fineness of the final product, can be slid into the appropriate section of the grinding path.
