steel plate shot blasting machine 4

Steel plate/ steel sheet shot blasting machines are specially designed for surface treatment to steel plates.

Steel plate shot blasting machines by QGMA adopt roller conveyor system to transport work-pieces through blasting chamber. The transport speed is adjustable by converter according to different work-pieces.

To achieve higher surface cleanness after blasting process for the next painting process, QGMA offers extra surface cleaning designs like scraper, roller brush or blower.
