Roller conveyor blast machine

Roller conveyor blast machines are mainly used for descaling and derusting profiles and sheet metal. A roller conveyor system, combined with corresponding cross conveyor units, allows individual production stages such as blasting, preservation, sawing and drilling to be interlinked. This ensures a flexible production process and a high material output.

Another area of application for the roller conveyor blast machines is the blasting of structures. Here, the turbine arrangement and throughput opening are adapted to the geometrically demanding workpieces. Our advice also includes the choice of suitable blasting media.

Determining the most suitable machine concept depends, among other things, on the nature of your workpieces, the quantity, the required output and, last but not least, your ideas regarding an optimised production process. These machines are often integrated into extensive roller conveyor systems with cross conveyors.

If the task cannot be solved with a standard machine, we will develop a customised machine concept for you.

Operating sequence for roller conveyor blast machines

 

The workpieces actuate the switching threshold located in front of the inlet sluice for the automatic blast media supply of the running high-performance turbines. This ensures that blasting only takes place when workpieces are in the blasting area.

The inlet sluice is equipped with wear-resistant rubber curtains for sealing. These are easy to replace. Sealing from below is achieved by means of an adjustable strip brush. After passing through the blast zone, the workpieces are transported to the combined brush and blow-off device. The abrasive remaining on the workpiece surfaces is fed back into the abrasive circuit.

The abrasive is kept in circulation and cleaned for continuous use.
The cleaned abrasive is fed from the abrasive hopper to the high-performance turbines via the abrasive dosing device.

A fan generates the necessary negative pressure to ensure dust-free operation of the blasting systems. The extracted air is cleaned with a filter system.
