Tube mills for raw material grinding are often equipped with drying compartments to evaporate the water contained in the raw material. The drying compartment is provided with lifters to obtain a dispersion of the material to be dried. For small mills, the drying compartment is often an integrated part of the tube mill as shown in Fig. 8 and Fig. 9.

If a ball mill contained only coarse particles, then 100% of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.
