May 23, 1932, No. 14650. Convention date, July 27, 1931. [Class 82 (ii).] Pulp is supplied to the centre of a verticallyreciprocating circular sieve, the tailings being discharged at the periphery and the concentrates passing through the sieve into the hutch. A circular sieve 10 mounted between two grids 8, 9 carried by spiders 7 on a hub 6 is vertically reciprocated by toggle mechanism. Pulp is fed tangentially through a pipe 43 into an annular launder 44 surrounding a shaft 21 attached to the hub 6 and passes into an annular feed chamber 46 at the centre of the sieve. The sieve is mounted in a conical hutch 2 having a pipe 3 for discharge of concentrates and a circular launder 4 surrounding the sieve for the tailings. A layer of coarse material is placed on the sieve 10 and the ore forms a bed 12 resting on this material, being kept in place by a lip 13 having an adjustable extension 14. A strip 19 of flexible material joining the lip 13 and the wall 20 of the launder 4 provides a fluidtight connection between the sieve and the hutch. Water is supplied to the hutch from an open tank 47, the level of water in which is adjusted and kept constant by a ball valve 48. The water flows through a pipe 50 issuing under a coned member 51 in the hutch, backflow being prevented by a non- return valve 52. A grid 18 is fitted in the hutch to prevent surging of the water. The mechanism for reciprocating the sieve is adapted to give a substantially constant acceleration for more than half of the downstroke, followed by rapid retardation and reversal. The shaft 21 carries a crosshead comprising cross-arms 22, 24 and connecting arms 23. A pitman 32, reciprocated by an eccentric 33 on a shaft 34, carries toggle links 25, 26, the latter of which acts on the cross-arm 24 while the former contacts with a member 27 on a fixed support 28.
