A ring mill (Fig. 1) is a grinding system well known to laboratories analysing inorganic materials, attributable to the friction mills category [1], [2]pared to other mill types, the ring mill enables much greater comminution of materials in the same grinding times. This mill type is used to cause mechanical-chemical and tribo-chemical reactions …

Ball and race mill is a mechanical device used for pulverizing the coal for combustion in boilers of thermal power plants. The ball and race mill consists of a lower grinding ring connected to the drive assembly through a mechanical part yoke and stationary upper grinding ring with the application of pressure from set of springs …

The laboratory disc mill enables fast, loss-free and reproducible fine comminution and homogenization of the samples. The grinding barrels can hold sample batches of 10 – 1000 cm³ and grind and homogenize the sample material to final finenesses of up to < 40 μm *1) in a single step. Sample preparation with a laboratory disc mill is thus the ...
