Abstract:
An apparatus for mixing granular material of fine particle size which comprises:a vessel for containing the granular material to be mixed; a stirring member rotatably disposed within the vessel; and pipe means for ejecting a gas into the granular material for conditioning the physical properties of the granular material being mixed in the vessel, said pipe means having an open end portion which defines a gas jet, said open end portion being inclined relative to the horizontal plane so as to extend rearwardly of the direction of rotation of the stirring member and downwardly, the angle formed by the end portion of the pipe and the horizontal plane being less than the angle of repose of the material being mixed, wherein the gas jet is provided in a fixed location relative to the vessel so as to enable the gas to be ejected from within the material being mixed, and enable the gas to be ejected forwardly of the direction of rotation of the stirring member.
