<p>The screening partition is composed of rectilinear and parallel bars (2), of identical and substantially circular, elliptical or octagonal sections, and of an annular support (3) fixed on the inner part of the shell (5) of the mill and on which are fixed the ends of the said bars (2). The bars form two parallel rows, the bars (2b) of the second row being offset transversely relative to those (2a) of the first row. The opening delimited by each pair of two adjacent bars allows the material to pass through but stops the grinding bodies. The annular support (3) comprises wearing plates which are solid or have slots arranged radially or concentrically. <IMAGE></p> |
