Abstract (en)
[origin: EP0736328A1] The fluidized bed grinder sends a high speed jet of gas or steam from a main nozzle (2) into the fluidized bed to draw in solid particles. Secondary nozzles (6,7) are also provided whose jet outlet directions (8,9) are inclined to that of the main nozzle so that the secondary jets project into the main jet stream immediately this has left the main nozzle. Preferably three secondary nozzles are arranged evenly spaced round the main nozzle with the outlet openings of all the nozzles lying in one plane and the jet axes of each of the secondary nozzles intersecting the main jet axis at an angle of 5 to 60 degs. The nozzles can open into a chamber directly behind the front end of a common nozzle housing
