The tunnel type shot blaster with overhead rail conveyor system is used to clean a series of parts for a confidential military corporation. By blast processing, it not only can remove the rust and slag from the steel structural components of engineering vehicle, and also can eliminate the welding stress and the fatigue strength, it will greatly increase adhesion force of the paint film during the components painting job, and finally improve the surface and intrinsic quality of the entire bulldozer. this shot blasting machine unit has the following characteristics.
- It can complete loading, fast running, running speed adjustment(down) by frequency inverter before blast processing, shot blast processing, speed adjustment(up) after blast processing, unloading, the hanger system with workpieces automatically return to loading station through the circular track, etc.
- The arrangement of the blasting turbines in the tunnel type shot blaster are determined by computer three-dimensional dynamic projection simulation.
- Straight-axis cantilever centrifugal blasting turbines with large shot blasting capacity (ORICA 400) and high throwing speed can significantly improve cleaning efficiency and obtain satisfactory cleaning quality.
- Spinner hanger system can rotate inside blasting chamber during blast processing for some special parts with the complex structure to blast cleaning all aspects of the pieces, and it can directly pass through the blasting chamber without rotating for some simple structure pieces.
- A blasting media collecting hopper and a high vacuum suction system can completely recycle the blasting media carried out by the workpiece and scattered on the ground.
- A blasting media replenisher is provided to replenish the blasting media consumed during blast processing.
- The HIM can show the blasting turbine accumulating working time to available to guide the replacement of wear parts such as blasting turbine blades.
The tunnel type shot blaster with overhead rail conveyor and spinner hanger system consists of a front vestibule, a blasting chamber with blasting turbines assembly, a rear vestibule, a circulation overhead rail conveyor system, a hanger rotation mechanism, High vacuum suction system, dust collector and electrical control part. The plate weldments of the machine are subjected to shot blasting to improve the rust prevention performance and the adhesion of the paint film.
