- Drum in manganese steel in one piece.
- Does not damage the blasted parts.
- Automated *loading / unloading system (*optional).
- Uniform exposure of the parts to blasting.

In this new equipment developed by CMV, tens of parts found in a conventional tumbling belt wheel blast machine are replaced with one single revolving drum.

This innovation prevents damages to the caging that occurs on the conventional tumbling machines. Besides, it substantially reduces the maintenance cost. In the majority of cases, the costs are reduced by up to 65%.

The drum receives the parts, which may be cast, forged, dye-cut, hardened, which need to undergo blasting or shot peening. The parts are blast with carbon steel grit or stainless steel shot, thrown by the CMV blast wheel.

The drum is made of a type of manganese steel that is extremely resistant to wear, with the objective to ensure a long useful life. Its cylindrical shape with pins in the interior and with the bottom in the shape of a pyramid, make the parts attain a “multi-tumbling”, which is a tumbling process of the parts in two directions at the same time. This tumbling in two directions ensures a better exposure of the parts to the blast wheel fan. This additional exposure, in conjunction with the concentrated blast on the parts to be blasted, allows a reduction in the blasting time.

Operational flexibility, operational efficiency and minimum maintenance are significant advantages of the CMV blasting machine with revolving drum. The machine operates automatically through load, cleaning and unloading cycles, thus significantly reducing the need of labor.

Launching of abrasive material: The CMV blast wheels, developed during years of research and experience, are extremely efficient and have the best energy cost / work performed ratio. Built with special steel alloys especially developed for the application of blasting, they have a long useful life, which translates in lower operational cost. In the TR type equipment, the blast wheels are equipped with pneumatic brakes, which contribute significantly toward the reduction of the operational cycle.

Reclaim of abrasive material: The abrasive material thrown by the blast wheel passes through small orifices located at the lower part of the revolving drum and is conveyed to the base of the bucket elevator, which conveys the abrasive material still contaminated by impurities to the abrasive purifier, which will operate through the air washing system. To complement this system, the equipment features a cyclone that prevents the loss of abrasive material to the exhaust system.

Exhaust System: Maintains the whole equipment under vacuum, thus preventing the loss of dust and residues to the environment. The use of high-quality cartridge filters and the correct sizing allow full compliance with the environmental protection and occupational health standards.

Hydraulic loader (optional): Designed to lift standardized containers, it contributes toward the reduction of the operational cycle time, and saves the operator's fatigue. It is especially recommended for equipment with higher capacity, such as that for 160 and 320 liters.
