Continuous shot-blasting unit with a special wear-proof steel wire mesh conveyor. The layout consists of a tunnel having the blasting room in the middle section. Turbines are mounted above the conveyor and are orientated in a way to ensure the perfect covering of the most complex parts. Final section of the tunnel is provided with a blowing system to remove the shots possibly remaining on the parts. The setup installation does not require a pit and is supplied with a dust collector system.
