摘要： A particle classifier comprising a casing, at least two separating wheels, a guide baffle, and a discharge conduit. The casing has a classification chamber and one or more openings that are provided to conduct air and particulate material into the classification chamber and to discharge course particles therefrom. The separating wheels are mounted in the classification chamber, and each wheel includes a multitude of blades forming openings for conducting fine particles into the interiors of the separating wheels. The guide baffle conducts air and particulate material entrained therewith upward to the separating wheels. The discharge conduit conducts from the separation chamber fine particles passing between the blade of the separating wheels.

摘要： The apparatus disclosed relates to a fluidized bed jet mill having a grinding chamber which is free of fixtures which is provided in its bottom region with a nozzle with a gas jet emerging vertically upward. The jet mill is configured such that when the grinding chamber is filled with the material to be reduced in size, material and gas emerge from the bed of material as a column of little speed. The column serves as a feeder for a classifier provided above the surface of the material bed and driven independently from the impulse of the jet emerging from the bottom nozzle. For improving the efficiency of energy utilization in grinding, a plurality of additional nozzles are provided. The additional nozzles discharge below the surface of the bed of material and into the grinding chamber. The orifices of the additional nozzles are uniformly distributed in a plane running perpendicular to the axis of the bottom nozzle. The additional nozzles are distributed about the circumference of a circle within the plane and coaxial with the axis of the bottom nozzle. The axes of the additional nozzles all intersect at a point on the axis of the bottom nozzle below the plane of the nozzle orifices.

摘要： A mill and operating method for using grinding bodies for grinding a grinding stock. Grinding bodies that have passed through the through the product outlet enter an upwardly inclined discharge pipe from where, when the grinding body mill is at a standstill, the grinding bodies are directed out of the discharge pipe through the product outlet into a rotor body of the separating device. When operation of the grinding body mill is resumed, the grinding bodies are conveyed back into the grinding chamber owing to the rotation of the rotor body.
