Roller shot blasting machine

Operation

All roller shot blast machines work in a similar way.

The workpieces first trigger a switching threshold in front of the entrance hall to the shot blasting area. This automatically releases the abrasive to the already operating high-performance turbines. This ensures that blasting only takes place when the workpieces are actually in the blasting area.

The inlet vestibule is equipped with wear-resistant rubber curtains that prevent the abrasive from escaping. The vestibule is sealed at the bottom by an adjustable scraper brush. After passing through the blasting zone, the parts enter a combined brushing and blowing zone. Excess abrasive remaining on the surface of the parts is removed and returned to the blasting process circuit.

The abrasive is continuously cleaned, recirculated and reused. An abrasive dosing device feeds the clean abrasive from the abrasive storage tank to the high-performance turbines.

A fan creates the partial vacuum necessary to maintain dust-free operation of the blasting unit. The extracted air is cleaned in a special filter unit.

Capabilities and applications

Shot blasting machines with roller conveyors are used to remove scale and rust from metal profiles and sheet metal components. By combining a roller conveyor with suitable cross conveyors, individual process steps such as shot blasting, preservation, sawing and drilling can be interconnected. This ensures a flexible manufacturing process and a high material yield.

Another field of application for the roller conveyor shot blasting machine is the shot blasting of large machine constructions. In these cases, the arrangement of the shot blasting turbines and the passages is adapted to the size of the workpieces.
