A tube mill comprises a coarse grinding compartment and two or three independent fine grinding compartments. Material fed into the mill is first ground by a coarse grinding compartment and then shunted into two or three portions which are conveyed into each corresponding fine grinding compartment. The mill of the invention has resolved the problems of overgrinding and unmatched grinding capability in each compartment of conventional tube mill, and increase output and decrease power consumption greately, so as to become a high eficiency mill. Further, the tube mill of the invention has the advantages of simple structure, ease for operation and low investment. It can be adapted for both reformation of prior tube mill and construction of new tube mill.
