Robust design, RANTEK Disc Mill can be used under rough conditions in laboratories and pilot plants, as well as online for the quality control of raw materials. 
The 2.2 kW Powerful Disc Mill requires only a few minutes to achieve the desired grind size.

Function Principle
In the Disc Mill the feed material enters the dustproof chamber from the filling hopper and is fed centrally between two vertical grinding discs. 
A moving grinding disc rotates against a fixed one and draws in the feed material. 
The necessary comminution effects are generated by pressure and frictional forces. 
The progressively arranged grinding disc meshing first subjects the sample to preliminary crushing; centrifugal force then moves it to the outer regions of the grinding discs where fine comminution takes place. 
The processed sample exits through the grinding gap and is collected in a receiver. 
The gap width between the grinding discs is continuously adjustable and can be adjusted during operation in the range 
between 0.1 and 5 mm; an additional observation window is provided for checking the gap setting.
