Depending on the manufacturer's process, the grinding is done wet, dry, or semi-dry. In vertical shaft ball mills, 65% of the particles are smaller than 45 microns, and the balls used are around 12mm in size. The rotational speed can vary between 60 – 80 RPM. A typical ball mill can generate 3500 tons of cement per hour.
