In tablet making activity the granulation process plays an essential role, because the quality of final tablets will be determined by virtue of the granules utilized for its compression. Oscillating Granulator comprises one rotor with five edges, which oscillates on horizontal axis. There is one half round sieve affixed at bottom of the rotor. The Product is charged from top through in feed hopper, and material falls on rotor lades. The particles are broken by a oscillating bars set, arranged in cylindrical form over an appropriate mesh screen. Due to the rotor sharp edges the downsizing of particles occurs and through sieve material gets forced outward from the bottom opening.
