FIELD: machine building.SUBSTANCE: plant comprises a chamber with grid floor, a hopper for abrasive particles and waste mounted under the grid floor, a transmission pipeline with inlet hole and a suction fan coupled with the transmission pipeline. A scraper fixed to a bearing element is mounted between the grid floor and the hopper. The bearing element is coupled with a reciprocation motion drive. The scraper is attached to the bearing element and can be fixed in the lower position at bearing element travelling to the inlet hole of the transmission pipeline and be lifted in the upper position at bearing element travelling from the inlet hole.EFFECT: simplified structural design of a plant, higher performance reliability and smaller dimensions by height.8 cl, 11 dwg |
