The workpieces, with their rims lying on the belt and the flat side leaning against additional side rails, pass through the machine on an continuous, wear-resistant rubber belt. Spindle-type lifting elements, positioned perpendicular to the direction of transport, can be adjusted to minimize belt wear.
Another guide rail on the opposite side completes the guidance of the workpieces. Belt feed and frictional resistance on the guide rails cause the workpieces to rotate continuously to ensure even exposure to the blast medium and consistent finishing. Even the ventilations (in ventilated discs) are treated at a high standard. The passage speed of the workpieces is controlled by the belt speed which is variable within a predefined range. A workpiece scanning system allows for specific treatment of individual parts.
Both lateral faces and the rims of the workpieces undergo focused blast cleaning without blasting interference. Treatment of individual parts in continuous passage (FIFO principle) provides consistent compliance with quality standards and process security. After passing through baffle and guide plates, the contaminants removed during shot blasting pass to a system where sand, scale and undersized abrasive grains are separated. On the outlet side, vibrating or roller conveyors can be provided to transport the workpieces to the next process, according to your requirements.
