Abstract

768,367. Pneumatic conveyers. ROAD MACHINES (DRAYTON), Ltd., and ROBB, W. M. Sept. 26,1955 [June 24, 1954], No. 18490/54. Class 78 (1). Bulk handling cement plant comprises a receiving hopper a, which is vented. to atmosphere, inclined delivery channels a<2> arranged below hopper outlets a<1> and provided with porous tile bottoms through which air under pressure passes to fluidize the material, and a rotary seal valve c for delivering the cement into a blowing chamber b<1> at the entrance to the conveying conduit b. An inclined baffle f in the pipe e connecting the blower g to the conduit b deflects some of the air into the valve c to assist the discharge of the cement into the chamber b<1>. Surplus air from the valve c is conveyed through the pipe n to the top of the hopper. A cut-off valve l is provided in the hopper outlet pipe adjacent the valve c. A non-return valve h is provided on the air supply pipe and a pressure gauge and safety valve k are provided on a branch pipe.
