<p>A method of grinding a batch of material, particularly ceramic material, together with a multiple of grinding media in a rotary mill drum which includes a polymer lining having elongated lifting devices which are positioned axially in the drum and which protrude radially into the drum interior. With the intention of making grinding more effective and of reducing grinding time, it is proposed in accordance with the invention that the method will comprise the steps of: rotating the drum at a constant speed in a first direction of rotation during a first time interval, so that grinding media from said grinding media multiple are brought into contact with a high-lifting side of the lifting devices as the drum rotates, to grind or disintegrate the material with a larger crush proportion and a smaller fine-grinding proportion; and - rotating the drum at said constant speed in a rotational direction opposite to the first rotational direction in a second time interval following said first time interval , so that grinding media in said grinding media multiple are brought into contact with a low-lifting side of said lifting devices opposite to the high-lifting side thereof, so as to grind the material with a smaller crush proportion and a larger fine-grinding proportion. The invention also relates to a mill lining for use with such a method. <IMAGE></p> |
