Abstract
Method and apparatus for the manufacture of chips from mineral, vegetable or embrittled materials. In the method the stationary wear plates and striking plates when worn from use are replaced during ball mill operation either continuously or periodically, either with or without pressure plates for the striking bars, and with different feeding speeds. The advance, or feeding, of these plates occurs in a time-dependent and/or energy consumption dependent manner. The apparatus includes a conventional beater mill equipped with a vertical or horizontal rotating beater wheel which has arranged on one or both sides of the stationary crushing path several magazines for storing wear plates and striking bars. The replacement of the wear plates and the striking bars is done by suitably constructed slide members.
