A method of separating and recovering a granulate from a viscous suspension containing said granulate and apparatus for carrying said method.

摘要

Method and apparatus for separating and recovering a granulate from a viscous suspension containing said granulate. The suspension is placed in a layer on an endless sieve belt guided around return rollers and effecting a separation into a sieve residue containing the granulate, which remains behind on the belt, and a stream of material passed by the belt. The stream of material is collected between the forward and backward runs of the sieve conveyor belt, and the separated granulate is dumped from the conveyor belt. According to the invention, as the layer of granulate containing suspension is placed, and resides on the sieve conveyor belt, at least one edge not defined by the edges of the sieve conveyor belt is formed and maintained on the layer. At least during the placement of the layer of viscous material on the sieve conveyor belt a stream of air maintained by one or more air moving means, such as blowers, is passed downwardly through the sieve conveyor belt and/or the layer is exposed to vibration via the sieve conveyor belt.
