APPARATUS FOR GRANULATION OF POWDER-LIKE MATERIALS Russian patent published in 2000 - IPC

FIELD: granulation of materials. SUBSTANCE: apparatus has a granulation chamber with a fluidized layer furnished with a gas-distributing grating, solution-injection nozzle, pipe connections for supply and discharge of the heat-transfer agent, and pipe connections for supply of source powder and discharge of finished granulate. Connected to the chamber are cyclone separators accommodating pneumatic ejectors in the lower part of their casings. The apparatus is furnished with an additional cyclone separator with a receiving bin for granulate. The granulate discharging pipe connection is located at the level of the gas- distributing grating and furnished with a valve and pneumatic ejector. The ejector casing (diameter of the holes - 3 to 7 mm, slot width - 2 to 3 mm). Rarefaction built up in the ejector should exceed the maximum possible rarefaction in the granulation chamber. EFFECT: continuous discharge of granulate disposed to adhesion from the granulation chamber, enhanced capacity. 1 cl, 1 dwg
