Description:

This Used Frewitt MG-636 Oscillating Granulator is a high-performance, pharmaceutical-grade granulation system designed to reduce, calibrate, or deagglomerate dry or wet powders. Built from 316 stainless steel, this unit features a 122mm (4.8") diameter x 17.25" long 5-bar rotor, producing up to 1000 kg/hr depending on the material.

Powered by a 1.5 HP, 3/60/208-230/460V motor, the machine operates through a reducer and is fitted with a bottom screen (approx. 1/16" holes) for precise granule sizing. Mounted on casters and includes an XP-rated control panel, this granulator is ideal for cGMP environments requiring mobility and safety. The machine discharges through an 11" diameter center bottom outlet with a 39" discharge height.
