The mill is not suitable for oilcontaining products capacity the filling hopper holding approx 4 kg has been mounted right on top of the grinding mill the mill is delivered with a 15 kw motor and the performance and degree of grinding varies from 30 75 kg wheat per hour depending on fineness of the ground product
A discharge screw at the lower end of the mill simultaneously extracts the blend of grinding beads and product the grinding beads are separated with a screening machine and returned to the mill because of the high fineness values produced with the mill virtually all products have a strong tendency to deposit and a grinding aid needs to be
