Abstract
A drying-grinding apparatus including two types of grinding means, one being arranged to produce a relatively coarse ground product, and the other being arranged to produce a relatively finely ground product. A drying gas is introduced into each of the grinding means, and a common conduit delivers the ground products from both of the two grinding means into a sifting means. The sifting means discharges relatively coarse particles into a metering means which receives the output from the sifting means and separates the same into two fractions one of which is returned to the coarse grinding means, and the other of which goes to the fine grinding means.
