The invention relates to a grinding plant and to a method of grinding and classifying brittle material for grinding, in which two classifiers are used. The finer fraction from the first classifier is delivered to a second classifier which separates it into coarse material and fine material. The coarse material passes into a fine grinding mill and from there is conveyed back to the second classifier by way of a mechanically transporting conveyor arrangement.

Grinding plant and method of grinding and classifying brittle material

The invention relates to a grinding process and apparatus for the simultaneous production of at least two finished products of differing fineness using a ring mill. Pre-classification is carried out in the nozzle ring by adjusting the air to entrain and carry upwards relatively fine constituents. The coarser constituents are discharged downwardly by gravity and subsequently may be conveyed upwards by an elevator and subjected to a second classification in which at least a proportion is extracted as finished product.
