Working Principle

In the DTF wheel blast machine, castings are continuously cleaned during an uninterrupted feeding process. The workpieces tumble in various directions within an oscillating chamber, ensuring all surfaces are impacted by the abrasive stream.

Alternative Version (More Technical):

The operational principle of the DTF series blast machine involves continuous processing of castings through a steady feed system. Components rotate multidirectionally in an oscillating chamber, exposing all surfaces uniformly to the abrasive blast flow.

Advanced DTF Blast System: Polygon-Trough Design for Superior Cleaning Performance

Unlike conventional drum-type throughfeed systems, the DTF series incorporates an innovative polygon-shaped trough with strategically positioned blast wheels aligned along the longitudinal axis above the casting flow path. This engineered configuration delivers unmatched cleaning efficiency for foundry operations.

Technical Parameters

Compared with traditional drum-type through-feed machines, Wheel DTF model features a polygonal trough design. The blast wheels are aligned longitudinally and positioned directly above the continuous flow of castings.

This innovative configuration offers several key advantages:

Continuous cleaning of mixed castings—including runners and risers—without the need for any manual intervention.

The polygon-shaped trough provides complete exposure of all casting surfaces to the blast stream while ensuring gentle and uniform tumbling throughout the process.

The system provides an extended blast cleaning zone, allowing castings to be evenly distributed for consistent processing.

With the blast wheels positioned directly above the material flow, abrasive energy is used with maximum efficiency.

Additional benefits of this design include:

No moving mechanical components inside the blasting area, eliminating the risk of workpiece jamming

Stable and controlled throughput of castings

High output capacity of up to 35 tons per hour, handling individual parts up to 150 kg

Simple and seamless integration of the DTF machine into existing production lines
