Abstract

1,248,251. Tube mills. F. L. SMIDTH & CO. A.S. 9 Jan., 1969 [16 Jan., 1968; 28 March, 1968], Nos. 2366/68 and 15006/68. Heading B2A. A tube mill comprises a grinding compartment or compartments 5, Fig. 1, and a short or intermediate compartment 6 downstream of the first or sole grinding compartment to serve as a reservoir for ground material which is fluidized by the ventilating air drawn through the mill. The partition 8 between the compartments 5 and 6 enables the fluidized material to flow from either compartment to the other. The downstream end of the compartment 6 has a wall 9 with an opening 14 (or openings) through which the ground material can pass, located so that a pool of fluidized ground material always exists in the compartment 6. The reservoir of material in the compartment 6 inhibits passage of material through the mill except at the rate at which it passes through the wall 9. Thus the grinding compartment 5 is permanently overfilled. Consequently noise, and wear of the mill lining are reduced. Partitions may have larger openings permitting easy airflow, and scoops 13 carried by vanes 22, Fig. 5, may be used in the intermediate compartment to facilitate control over the lever of the fluidized material. In a further embodiment, a pair of rings 30, 32 Fig. 7, surround solid central portion 27 and shroud an opening 31 in a partition 25 so that material flows down the surface of the fluidized pool while the opening remains shrouded. The mill may be controlled by a known microphone, transmitter and amplifier arrangement.
