Abstract
427,671. Ball mills. BARRATT, F. R., 12, Otto Street, Krugersdorp, Transvaal, South Africa. March 20, 1934, No. 8729. [Class 59] In a ball mill the ground pulp is discharged through a tapered trunnion forming a classifying chamber, a screen being arranged between the end mill compartment and the classifying chamber to retain the grinding bodies and to permit free flow of ground pulp between the chamber and compartment. As shown the mill 2 is mounted on rollers 9 and is driven by belts 8. A perforated partition 10 divides the mill into compartments and the size of the perforations may be varied by rotating a similar partition 15 to partially mask the holes. The outlet 6 is of conical form and is provided with a central tube 19, through which liquid or balls may be inserted in the fine grinding chamber 12, the pulp passing through perforations 18 around the tube 19. The size of the inlet orifice 5 and outlet orifice 6 may be varied by using different end plates. The linings are of corrugated form, that in the coarse grinding chamber 11 being arranged helically.
