Surface International tumblast machines are designed for batch operations. Appropriate loading and unloading devices can be used to integrate the shot blast machine into an existing production plant to create a continuous work flow.
The loading device delivers the workpieces to the trough-shaped shot blast chamber consisting of a continuous rubber conveyor belt or a steel apron conveyor and adjustable lateral disks. Shot, burrs, flashes or scale and sand deposits are removed by the lower vibrating deck before the separator (optional on smaller machines). Belt speeds can be adapted to the tumbling behaviour of the workpieces, thereby allowing for individual dwell times during the blasting sequence.
With the belt running in the reverse direction, the workpieces are unloaded from the machine to be placed in containers or on conveyor belts. Loading / unloading is aligned with production requirements: Manual, mechanic & automatic loading allows integration of Surface International tumblast machines in continuous production sequences.
Optimised shot blast effect
During shot blasting, the workpieces, regardless of size and shape, are evenly and continuously tumbled. This is necessary for the effective and uniform treatment of all surfaces.
During tumbling, the workpieces continually undergo shot removal, enabling workpiece interiors and cavities to be perfectly cleaned. For the complete removal of all shot, the final tumbling time that follows the shot blast sequence can be regulated to suit the type of workpieces being blast cleaned. The tightly sealed, leak-proof blast chamber minimises shot consumption
