S G Pharmatec Multi Mill is a self contained portable unit useful for high speed GRANULATING, PULVERISING, MIXING, SHREDDING AND CHOPPING, etc., of a wide range of wet and dry materials without special attachments. As compared to the four common principles of size reduction i.e. grinding, compression, impact and shearing, which often do not produce controlled size reduction, this machine utilises the principle of variable force swing hammer blades having both knife and impact edges rotating with a carefully selected screen to control size reduction.
