CENTRIFUGAL SEPARATOR FOR POLYDISPERSED MATERIALS Russian patent published in 1995 - IPC

FIELD: heat and power engineering. SUBSTANCE: separator has the outer cone body 1 with the cover 2, the inner body 3, the branch pipe for outlet of a ready product, swirling blades 5, mounted on axles 6, arranged over an upper edge of the inner body 3. The upper edges 15 of the blades 5 are displaced relative to the lower edges of the blades towards blade rotation side by a value, given in a description of the invention. An initial material is fed through an annular duct, restricted by the outer 1 and by the inner 3 bodies of the blades 5 respectively. The stream is being swirled, and then it is being fed to a separation zone. Large dimension particles are being moved to the wall of the body 3, along which these particles are being poured. Small dimension particles are being drained through the branch pipe 4. EFFECT: enhanced accuracy of fraction separation. 1 cl, 4 dwg
