Door Hook Type Shot Blasting Machines operate on a batch-type overhead hook principle where components are suspended from rotating hooks mounted on a carrier beam. The door-mounted hook system allows easy loading and unloading of workpieces directly from the front, enabling operator-friendly batch processing.
As the hooks rotate, high-velocity abrasive shots are projected by centrifugal blast wheels from multiple directions, ensuring 360-degree uniform surface cleaning. This removes rust, mill scale, welding slag, and surface contaminants while creating a consistent anchor profile for superior coating adhesion.
The spent abrasive is collected at the bottom hopper, elevated via a bucket elevator, cleaned through an air-wash separator to remove dust and debris, and continuously recycled back to the blast wheels. A dedicated pulse-jet dust collection system maintains a safe, compliant working environment throughout the blasting cycle.
Surface Preparation Technologies has established itself as a trusted manufacturer of door hook type shot blasting machines through precision engineering, heavy-duty fabrication, and dedicated after-sales support. Our machines operate across structural steel fabrication, automotive component manufacturing, heavy engineering, and general metal fabrication industries.
