Tumbling drum OB 850
The tumbling drum OB 850 is a machine designed for mechanical cleaning, degreasing and polishing of nails of 2.5 mm dia or bigger, or for processing of similar products. The products are processed in fine wooden sawdust. The machine does not require continual supervision of the operator, as the time relay would stop the machine after the preset optimal processing time. The sawdust and the other impurities can be vacuum-separated from the products during the tumbling process, so that the finished products are poured out into a suitable container located below the drum.

The drum has two rotating modes - the conti-nual-operation mode, controlled by the time relay and the stepping mode, when the drum rotates only at depressed push button at the control panel. This mode allows to stop the drum in any desired position. The drum design allows to exchange the sieves in dependence on size of the processed parts. Inside of the drum suits to vacuum-separation of the sawdust and metal flashes (the wings, etc.). The filling equipment and the vacuum equipment are not a part of the delivery.
