Hook Type Shot Blasting Machine QJ376–QJ3750 | Jinwo, Qingdao, China

Jinwo's Hook Type Shot Blasting Machine QJ376–QJ3750 is a suspended, batch-type machine that cleans and prepares the surface of medium and large castings, forgings, weldments and heat-treated parts. It removes oxide scale, rust, burrs and moulding sand.

An electric hook lifts and rotates each workpiece inside the cleaning chamber while blast wheels throw abrasive at it from all sides, giving full coverage with no dead spots. This makes it well suited to slender, thin-walled, fragile or irregularly shaped parts that must not knock against each other. Some models can also strengthen the surface.

It is offered in single-hook and double-hook versions, in six sizes, and non-standard customisation is available.

Key Features

• Suspended batch design with an electric hook that lifts and rotates the workpiece
• 360° projectile flow from the blast wheels for full coverage
• Hook stroke combines self-lifting, horizontal movement and rotation inside the chamber
• Hook arrangement makes loading and unloading easy
• Pneumatic control of the main door and shot gate
• Pulse reverse-blowing dust collector for automatic dust removal
• Compact footprint with simple installation

Frequently Asked Questions

• What size of workpiece can it handle? Maximum suspender dimensions range from 800 × 1,000 on the QJ376 to 1,800 × 2,500 on the QJ3750, with maximum cleaning weights of 500–5,000 kg.
• Is it suitable for fragile or thin-walled parts? Yes, the workpiece hangs from a rotating hook rather than tumbling, so slender, thin-walled and irregular parts are not knocked together.
• Does it include dust collection? Yes, it has a pulse reverse-blowing dust collector that removes dust automatically.
• What should I send for a quotation? Send the workpiece types with their maximum dimensions and weights, the surface condition (scale, rust, sand), whether you want a single-hook or double-hook version, batch sizes and any customisation needed.
