TUMBLING MACHINE

A tumbling-blast machine, consists of an exclosed, endless conveyor belt, a centrifugal blast wheel and an abrasive recycling system. These machines simultaneously tumble and blast the work pieces. As the conveyor moves, it gently tumbles the work and exposes all work piece surfaces to the abrasive system.

Tumblast machines are used for cleaning unmachined castings, forgings, and weldments whose size, shape and material permit them to be tumbled without damage. This machine is not used for cleaning of parts after machining, because tumbling damages machined surfaces. Tumbling blasting machines remove dry contaminants such as sand, rust, scale and welding flux and provide surface preparation for enameling, rubber bonding, electroplating or etching before tinning.

Tumblast machines can be integrated into automatic systems for high production rates. An example is the presort and tote box loader work handling system.
