Abstract:
Provided is a method for drying and comminution of moist, mineral raw materials, including at least one of chalk, marl or clay. The moist, mineral raw material is dried and comminuted in a drier crusher while simultaneously supplying hot gases from a kiln system to form a dried material. The dried material in suspended form is directed to a first separator in which the dried material is separated into a coarse fraction and into a fine fraction. The fine fraction is directed to a separation cyclone and then to the kiln system. The coarse fraction is directed to a dosage means. The dosage means directs a first portion of the coarse material to the drier crusher and a second portion of the coarse material to a separate grinding unit where any hard material components, including at least one of flint, sand or marble, are subjected to grinding to form a ground material. At least a portion of the ground material from the separate grinding unit is supplied to the drier crusher. Also provided is an apparatus for conducting the method.
