CA 2066473

Apparatus for grinding particulate solid material in a substantially dry state, the apparatus comprising, means for introducing particulate solid material into a grinding chamber (4), a perforated base (8) of the grinding chamber (4) through which gas is introduced to provide an upward flow of gas passing through the particulate solid material and an impeller (42) rotating in the grinding chamber (4) to agitate the particulate solid material. The perforated base (8) has a central imperforate area (10) which causes the gas to pass preferentially through the region near the walls of the grinding chamber (4). In addition, a horizontal baffle plate (17) having a central opening (18) is positioned in the grinding chamber (4) at a height above the perforated base (8) which is not greater than one half of the transverse width of the grinding chamber (4). The horizontal baffle plate (17) is provided to prevent the bed of particulate solid material from extending upwards to an undesirable degree near the walls of the grinding chamber (4). The grinding apparatus may be used with advantage in surface treating an inorganic material.
