DTC Batch Type Blast Cleaning Machine
18 weeks +
Cleaning, Corrosion Removal, Shot Peening
Blast cleaning of mixed production runs
High cleaning capacity due to very short loading and unloading times
Polygon shape of trough ensures complete but gentle tumbling of parts
Full exposure of workpieces to the blast stream
- Simple operating principle, compact design
- Optimum location of blast wheels throughout the trough, optimum utilization of the abrasive energy
- Full exposure of all workpiece surfaces to the blast stream
- Short blasting times due to a long blasting zone and low density of parts
- No moving plant components within the blasting zone
- Small drop heights at loading/unloading
- Less impact damage, no workpiece jamming
- Easy integration into existing production lines
- Desanding and decoring of castings
- Descaling of castings, forgings and heat treated parts
- Shot peening (without process security)
Simple Operating Principle
Sequence of Operations
The loading system delivers parts to be cleaned to the polygon shaped trough which rocks back and forth about its longitudinal axis through 120°ensuring gentle but thorough tumbling of the parts being cleaned. The swing speed is adjustable and can be set in accordance with part size, shape and configuration.
The blast wheels are located directly above the workload and focus the abrasive stream on the workpieces.
The wheels are arranged lengthwise – one behind the other - which ensures optimum blast cleaning and maximum energy utilisation during blast cleaning. Abrasive, burrs, scale and sand deposits drop through the perforated section of the drum onto a conveyor which then removes coarse particles.
After blast cleaning, the polygon trough which is made of highly wear-resistant material turns about 180° and releases clean parts onto a vibratory conveyor and onwards to a transport bin or belt.

The blast wheel is the heart of the blasting machine, as the choice of blast wheel determines the power output and the economics.
This machine is fitted with U70x500 Universal (indirect drive) shot blast wheels as standard. The Wheels are highly flexible, compact and have rotation in both directions. They provide perfect blast cleaning results and highly convenient servicing features.
The U Blast Wheels are high capacity blast wheels with maximum energy efficiency. Their rugged design means that maintenance is easy, and the special and highly wear resistant cast alloy liners ensure minimum wear and maximum service life of the blast wheel.
