The static sieve works like roughing. Made of stainless steel, this machine receives the pour over a filter mesh arranged in a curved way, with a certain size of light. The water passes inside the sieve while the solids remain outside the filter mesh. A vibration system helps the solids to detach towards the lower part of the filter mesh. The chipped water is discharged from the back of the screen. Filter mesh cleaning systems can be installed using pressurized water nozzles, for this a water tank and a pump are installed.
