Abstract
A device for treatment of articles in a fluidized bed of abrasive grains comprises a working and an additional receptacle (1 and 2) and a valve mechanism (3). The working and the additional receptacles (1 and 2) have a common bottom (4) consisting of a distribution grid and are separated by a partition (5) with an opening (6), each of the receptacles (1 and 2) being provided in their upper part with an outlet orifice (7 and 8) respectively. The valve mechanism (3) comprises a rocker (9) and two valves (10 and 11) secured on the rocker (9) with this possibility of closing, in turn, the outlet branch pipes (7 and 8) of the working and the additional receptacle (1 and 2).
