PURPOSE:To contrive not to contaminate working environment due to generation of dust and scattering of projected material in transit by constituting such that projected material to be recovered is transported through cylindrical bodies in the hermetically enclosed state. CONSTITUTION:Piston members 13, 13 are arranged at the intermediate position between two cylindrical bodies 3, 3', and respectively tightly fixed to the tips of rods 11a, 11a' with both rod cylinders 11 which are fixed through holding legs 12 on a foundation frame 1, and these members 13, 13' are installed in the cylindrical bodies 3, 3' movably in its sliding motion. Projection material 16 which has been projected by means of a projecting device of a shot blast equipment is poured into the cylindrical body and when it fills the vicinity of a feeding hole 3a, an electromagnetic 15 is demagnetized, and the both cylinders 11 are set to the operated. Further, the projected material is extruded and moved to the right side by means of a piston member 13, it is magnetized by means of the electromagnet 15, and set in solidified condition. Thus, generation of dust and scattering of the projected material can be prevented. |
