Model:Q69 Roller conveyor type shot blasting machine
Send Inquiry
This series of machines is a continuous pass-through type machine for automatically blasting plate and large other structural steel components placed onto a roller conveyor. Work pieces with overall dimensions not exceeding the specifications can be blasted in a continuous operation. Each machine is provided with an integrated roller conveyor for powering the work pieces beneath the blasting wheels. The blast wheels are mounted above and below the conveyor at optimum angles for effectively blasting all exposed work piece surfaces.
