Roller conveyor machine is mainly used for processing long and (or) flat shape of the workpiece. These workpieces are continuously passed through the entering chamber, the shot blasting chamber and the cleaning chamber on a special conveyor roller table.

Qingdao ANTAI roller conveyor blast machines are designed as an optimal processing solution for steel plate/sheet metal, steel profile/beam/sections(H-beam, I beam, C-beam), steel pipes/tubes and steel structural framing, deformed steel bar etc, with residue from the shot’s abrasive action handled via a blowing and brushing system that ensures every last trace is removed.
