RUBBER BELT CONVEYOR TUMBLAST MACHINES

The SSEC Tumblast cleaning machine offers favorable, convincing solutions for blast cleaning of small and medium size work pieces, in batch quantities. The TB series will accommodate batch weights of 180kg to 1360kg. The applications of these machines are especially variable: Blast Cleaning of iron castings, precision castings, and die castings Descaling of forgings or heat-treated work pieces Shot peening for surface compaction Deburring of metallic (e.g. stampings) and non-metalic work pieces Surface finishing.

Tumblast cleaning machines have been successful over several years and in thousands of applications, often in multi shift operation. The TB series have proved to be economical for low production and optium blast cleaning. The TB series offers the following advantages:

• Attractive Price/Value ration
• Rugged,Compact design
• Ease of Operation
• High blast cleaning performance
• Quick and easy replacement of wear parts

Design and Sequence of operations

Depending on the weight,size,volume and flow rate of the castings to be cleaned, the machine can be loaded in a manual, mechanical, or automatic mode. The work pieces are then tumbled inside the blast cleaning chamber consisting of a continuous troughing rubber belt conveyor and lateral discs of highly wear resistant material. Specially designed rubber belt conveyor assure gentle tumbling and full exposure of all surfaces. Burrs, scale or sand drops passes through the perforations to the bucket elevator and the separator. After passing through the separator for removal of impurities, the abrasive returns to the storage hopper.

Mechanical loaders are used for the machine on special request. The Shot blast machines can receive the parts to be cleaned directly or using separate transport bins of the standard sizes.

SSEC blast wheels are renowned for high capacity and maximum energy efficiency. These blast wheels come in various power ratings, giving a high degree of flexibility. With modifications it is possible to reverse the blast wheel rotation thus allowing a greater range of applications. The amount of abrasive can also be adjusted. The abrasive is mechanically pre-accelerated and delivered to the blast wheel in a continuous stream, this ensures optimal utilisation of the power from the drive motors. High wear resistant material ensures maximum service life of the blast wheel. Unique design features allow for rapid and simple replacement of wear parts.
