Multimill is used for high speed granulating, pulverizing, 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 reductions i.e. grinding, compression, impact and shearing, which often do not produce controlled size reduction, this machine utilizes the principle of variable force swing hammer blades having both knife and impact edges rotating with a carefully selected screen to control size reduction. Flow path of material in vertical rotor machine is streamlined. During Communication , material entering the chamber travels to the periphery and passes through the screen tangentially and radially avoiding chocking and temperature rise.
