The Laboratory Oscillating granulator is for wet and dry granulation widely used in research laboratories of pharmaceutical, food and chemical industries. Product is charged from the top through in feed hopper and material falls on the rotor lades. The particles are broken by a set of oscillating bars arranged in cylindrical form over a screen of suitable mesh. Due to the knife edges mounted on rotor, the downsizing of particle takes place and through sieve material gets pushed outward from the bottom opening.
