Rösler RRB 27 6

Rösler RRB27/6 Roller Conveyor Shot Blasting System

Blast Cabinet
Tunnel-shaped design based on the pass-through principle, built solidly and robustly with highly wear-resistant construction with a pre-chamber, blast chamber, and after-chamber.

Pre-Chamber
Protected against wear, with a series of rubber protective curtains between the rollers of the roller conveyor to protect against the escaping blasting media.

Blast Chamber
Completely lined with manganese steel for wear resistance, with additional gap-free, hung, and/or bolted protective plates made of high-strength manganese steel.

After-Chamber
Lined against wear, with a series of rubber protective curtains between the rollers of the roller conveyor to protect against the escaping blasting media.

Blast Chamber with a large inspection door with electromechanical limit switch safety devices.
