Continuous blast-cleaning machine with a conveyor permeable to abrasive

摘要

The invention relates to a continuous blast-cleaning machine with a conveyor permeable to abrasive for the continuous blasting of material to be cleaned, in particular castings which cannot be rolled and are sensitive to blows and shock. The object of the invention is to design the covering of the conveyor of a continuous blast-cleaning machine in such a way that workpieces of various size and structure can be treated all over. According to the invention, the object is achieved in that a conveyor, consisting of two tension members circulating parallel to each other in a vertical plane via drive and return wheels and of centrifugal wheels arranged above and below the conveying plane, is covered with individual grid elements. The invention can be used in cleaning processes, in particular in foundry practice. <IMAGE>
