We are offering vibrating sieve machine for grain. This double sieve machine is designed to separate the larger and finer bodies among the product. There are two versions available: with or without the aspiration system. operationthe product enters by way of gravity into a dispensing hopper and is uniformly distributed over the entire width. The product descends onto one or more sieves, which separate the impurities according to the type of perforations. As it exits, the product encounters a cross air flow which removes any dust and impurities that are still present.
