Precious Cone Mixer Cum Blenders may be either in M.S. or S.S. as the requirement may be the central part of the vessel is cylindrical while the ends are of conical shape. At the tip of one of the cone there is a feed mouth while at the tip of another cone a discharge gate with butterfly or some other type of valve is provided. The double conical vessel rotates with the filled material, with the help of gear box and electric motor. Because of its particular shape material moves not only up and down but has steering effect which gives a good homogenous mixing/blending of the powders.
