ABSTRACT:
In a vertical loop jet mill, a grinding chamber in the lower part of the loop is trapezoidal in shape with side walls converging toward the outside of the loop. Removable nozzle plates are provided in the lower parts of the side walls of the grinding chamber, and the nozzles are directed so that gas streams from nozzles on one side intersect gas streams from nozzles on the other side. A removable insert, with trapezoidal end panels forms the upper wall of the grinding chamber.
