Volumetric metering device for particulate solids

摘要: 1,241,446. Metering particulate material. ESSO RESEARCH & ENG. CO. 4 July, 1968 [18 1967; 3 June, 1968], No. 31922/68. Heading B8N. Apparatus for metering volumetric quantities of abrasive solids comprises a wall defining housing 29, rotary drum 31 mounted on substantially horizontal axle 38 extending through the housing, recesses provided by radial blades 32 and side walls 36 1 , 2 collecting fed thereto as is rotated, an inlet 30 downwardly from elevated source conveying to recesses, terminus being located sufficiently close so that each recess when beneath will be filled depth no greater than at which material can attain its angle repose without overflowing outlet below drum, means rotating drum. The outermost circumferential are spaced internal distance maximum particle size metered. As described, apparatus used iron ore particles reactor, 29 pressurized. may have plurality across width shoot rectangular or triangular section end with shroud extends parallel surface. A skewed relationship between increment spread over several recesses. This effected locating length providing separated oblique blades.
