  The coarse material separated out in the gravity separator 56 collects in the lower conical portion of the separator above a rotary valve 82, like valves 65 and 15, which is adapted to seal off the separator 56 and at the same time deliver the coarse material into a duct 84 connected into the supply chute 42 so that the coarse material is returned to the mill l0 and subjected to regrinding along with the fresh material introduced thereinto.The structure of the improved partition wall is shown in detail in Figs. 2,used cone crushers 3 and 4, from which it will be seen that the wall is made up of a plurality of similar radial sections 85, each having the peripheral sectional flange 30 cast integral therewith. In addition to the radial sections 85, the wall includes 2 similar but slightly narrower radial sections 86 on opposite sides of a radially extending partition wedge 81 which is slightly wider at its inner end than at its outer end.
  
  When this wedge 8! is inserted and pulled toward the periphery of the shell ID by screwing up the nut 88, force is applied to the adjacent edges of the radial sections 86 so as to tighten up the entire set of radial sections and 86. The ends of the flanges 30 of the sections 85 and 8B are separated by angle-shaped filler or spacer plates 89 which bear against a liner 98 which lines the inside of the shell I9.The inner ends of the radial sections 85 and 86 are each bolted to key plate Si by means of bolts 82,coal mining equipment manufacturers the plate 9| having the structure and reinforcing flanges shown in Fig. 3, so that a rigid wall structure is provided. It will be noted, as shown in Fig. 3, that'each of the sections 85 and 86 bear against a flange 93 of theiplate 9i and also against the inner base member in the same plane as the face of the flange. The inner end of glzie wedge 81 is bolted to the plate 9| by. a bolt An important feature of my invention is the provision of a partition'wall having a structure which is correlated with the inlet and outlet trunnion passageways and with the size of the balls used for grinding the material to be pulverized. Accordingly.
  
  I advantageously provide radial sections 85 and 86 with relatively large openings for air flow through which balls of relatively large diameter are adapted to pass into the outlet compartment, but which will not pass the large balls 24 until they are worn down to the proper size. The balls 24 are of large diameter. Each radial section 85 or 86 is therefore provided with openings or passageways 94, all having approximately the same width, but which may vary in length in the manner and proportion illustrated. The sections 85 and 86 may also include the cross-shaped openings or passageways 95 which have the same effective width dimension as the passageways 94. The key plate 9!, in its central portion also has passageways 94 for the flow of air and pulverized material.
