FIELD: process engineering.SUBSTANCE: invention is intended for use in chemical industry, agroindustrial complex, construction, etc. Accelerator comprises material feeder, accelerating nozzle with rotary drive composed of two coaxial hollow inner and outer truncated cones with their larger bases set downward, inner cone being connected with said feeder. Nozzle tubes are arranged at nozzle lower part, inner tubes being connected to inner hollow truncated cone while outer ones are connected to outer truncated cone. Note here that circular air chamber is arranged above the nozzle with vertical pipes arranged in circular chamber between hollow truncated cones connected thereto. Note here that air direction blades are mounted at outer cone inner surface to feed air to outer radial nozzle tubes with outer conical ends.EFFECT: efficient acceleration, simplified design and power savings.2 dwg |
