LOOSE MATERIAL PNEUMATIC SEPARATOR Russian patent published in 1999 - IPC

FIELD: agricultural engineering, civil engineering and chemical industry. SUBSTANCE: separator has vertical pneumatically separating channel with feed port, hopper communicating with pneumatically separating channel, charging branch pipe communicating with feed port, separated product receivers. Separator has flat nozzle installed under charging branch pipe and communicated with additional feed port made in pneumatically separating channel under main feed port and horizontally installed under hopper before place of mating of charging branch pipes. EFFECT: increased efficiency of separation owing to reduction of screening effect, i.e. entraining of heavy particles by light particles and light particle by heavy particles. 2 dwg
