Sieving Apparatus And Method Of Using Same

A method for separating solid particles above a predetermined size from a solids-containing fluid, the method comprises the steps of:

• passing the solids-containing fluid through a sieving device (1) provided with at least two sieving cloths (10, 20), and wherein the sieving apparatus (1) comprise an inlet portion (3) for receiving the solids-containing fluid, an discharge portion (5) for solids that is retained on the sieving cloths (10, 20), and an outlet portion for fluid that has passed through the sieving cloths (10, 20);
• carrying the solids-containing fluid across at least one sieving cloth (10) arranged in a frame (16) connected to a shaking device (18) for providing a shaking motion, so as to provide a relative movement between the sieving cloth (10) and the solids-containing fluid, and over an endless sieving cloth (20) arranged for rotating around at least two spaced-apart turning-rollers (22), wherein the solid particles in the solids-containing fluid is carried by the sieving cloth (20) substantially without being moved relative to the sieving cloth (20), but where a portion of the fluid is separated from the solid particles by means of a pumping device (26) being in fluid communication with a suction nozzle (24) which is located proximate an underside of the endless sieving cloth (20) between two of the turning-rollers (22) in order to provide a fluid flow through at least a portion of the endless sieving cloth.
