FIELD: technological processes.

SUBSTANCE: invention relates to mechanical separation of suspensions. Arc sieve for mechanical separation of suspensions includes fixed housing with feeder and distributor of separated suspension along width of screen in upper part, receivers for removal of oversize fillet and undersize filtrate in lower part and arched filtering baffle arranged in housing in convex side opposite to receiver of undersize filtrate, fencing feeder with distributor from receiver of undersize filtrate, on side of which transverse deflectors are connected to it. Sieve is equipped with a vibrator, and at the lower part of the filtering partition there is a transverse partition connected to the vibrator along its width, forming a wedge-like space with a gap with the filtering partition wall converging to the bottom.
