Hook Shot Blasting Machine



1. Brief Introduction

Hook type shot blasting machine is a widely used surface treatment equipment in foundry, forging, machinery manufacturing and heat treatment industries. It belongs to overhead hanging shot blast equipment, mainly used for descaling, rust removal, oxide skin cleaning and surface strengthening of medium & large castings, forgings, structural parts and heat-treated workpieces.

The workpiece is suspended by lifting hooks; the hook can lift, rotate and move into the blast chamber automatically. High-speed rotating blast wheels throw steel shots at high velocity to impact the workpiece surface, removing rust, scale, burr and contaminants efficiently without chemical pickling.

2. Main Structural Composition

①.Hanging Hook System: Consists of lifting hook, driving motor and rotating mechanism. It realizes workpiece hoisting, in-chamber rotation to ensure all-side uniform blasting; single/double hook designs are optional for different productivity demands.

②.Blasting Chamber: Welded thick steel plate cabinet lined with wear-resistant guard plates, sealing structure to prevent shot leakage and dust overflow, providing closed blasting working space.

③.High-efficiency Blast Wheel Units: Core working component, multiple blast wheels arranged rationally according to workpiece shape to cover full workpiece surface with projectile coverage.

④.Shot Circulation System: Includes bucket elevator, screw conveyor and separator. It recycles, separates qualified steel shots from broken shots, dust and impurities, and feeds intact shots back to blast wheels for cyclic use.

⑤.Dust Removal System: Matched with pulse bag dust collector, collects blasting dust and exhausts clean air up to environmental protection standards.

⑥.Electrical Control Cabinet: PLC centralized control, automatic/manual switching modes for easy operation and safety interlock protection.

3. Key Features

①.Fully enclosed blasting structure, low dust emission, environmentally friendly, replaces traditional acid cleaning process.

②.Hook rotary design ensures uniform shot impact, consistent surface treatment quality for complex-shaped workpieces.

③.Automatic shot recycling & screening reduces shot waste and lowers production cost.

④.Wear-resistant lining and high-quality blast wheel extend equipment service life, low later maintenance cost.

⑤.Flexible configuration: single-hook / double-hook models available to meet different workpiece weight and production capacity requirements.

4. Application Scope

Suitable for surface cleaning of automotive parts, engineering machinery components, casting parts, steel structural parts, gear parts, hardware forgings, hydraulic parts and other heavy workpieces; widely applied in auto manufacturing, construction machinery, casting factory, ship accessory processing, valve industry etc.
