Disc grinders are designed for comminution of samples of bulk materials to a fine-grained state.
In disc grinders, comminution occurs by means of abrasion – simultaneous compressive and shear strain of material particles between fixed and moving discs.
The grain size of the comminuted product is regulated by the gaps between the discs (openings) and the physical properties of the material.
The Disc grinder DG 65 is designed for comminution of small samples weighing up to 1.0 kg for analytical studies with strict requirements relating to sample purity: the sample is not contaminated by working parts of the grinder.
The Disc grinder DG 175М is a tabletop model of the DG 175. In addition to the reduced overall dimensions of the grinder, the method for adjusting the gap between the discs has been changed. This makes it possible to perform the adjustment while the electric motor is operating.
The Disc grinder DG 200 is a more powerful model of the laboratory-class equipment. It can be used for comminution of small samples weighing up to 3 kg, as well as for continuous comminution, by outfitting it with 1.8L or 10L receiving containers, as well as Feeders VF 1 or VF 2.
The Disc grinder DG 250 is high-power equipment designed for busy laboratories or small production facilities.
