- Product Description
Hook Type Blaster – Collision‑Free Hanging Shot‑Blasting System for Precision Surface Treatment
Hook Type Blaster is an industrial‑grade solution provided by Botou Junda Machinery Equipment Co., Ltd., specially designed for fragile and complex workpieces. Backed by our 3,000 m² manufacturing plant and over 20 years of casting‑machinery expertise, our hanging shot‑blasting system delivers dual‑turbine 360‑degree coverage, Sa2.5 surface quality compliance and VFD‑adjustable hook speed. High‑chromium alloy blades and high‑manganese steel liners double the service life of wear parts, lowering replacement costs for power generation, metallurgy and automotive foundry applications. The single‑hook version supports loads up to 800 kg with maximum workpiece dimension of φ1200×1800 mm.
What Makes Our Hook Type Blaster Stand Out
Our Hook Type Blaster adopts a collision‑proof hanging design to prevent deformation of thin sheets, precision moulds and welded assemblies. Workpieces rotate freely while suspended, eliminating part‑to‑part damage commonly seen in tumble‑type blasting machines.
Symmetric dual blast wheels provide full 360‑degree cleaning. Heavy mill scale and stubborn rust can be removed in one pass to achieve ISO 8501‑1 Sa2.5 cleanliness standard. Manual grinding is eliminated and labour costs are reduced accordingly.
Dual variable‑frequency control enables independent adjustment of rotation and lifting speed. Low‑speed rotation extends blasting exposure time for heavy rust removal, while high‑speed rotation boosts throughput for small‑batch processing.

Core Operational Advantages
Collision‑Free Hanging Design
Thin aluminum components and precision welded parts rotate without physical contact with one another. The deformation rate is reduced to nearly zero, protecting high‑value finished workpieces.
Dual‑Turbine Full Coverage
Oppositely‑mounted blast wheels eliminate blind spots. Heavy rust layers and heat‑treatment mill scale are completely removed with no secondary finishing required.
Adjustable Hook Speed
Variable‑frequency drives independently control rotation and lifting motions. Large castings undergo prolonged blasting at low speed, while small‑size parts benefit from accelerated cycles.
Extended Wear‑Part Service Life
Full high‑manganese‑steel chamber liners and high‑chromium turbine blades reduce wear rates. The replacement interval for consumable parts is doubled compared with standard carbon‑steel components.
Closed‑Loop Abrasive Recovery
Bucket elevators and screw conveyors feed material to the pneumatic air classifier. Broken shot and dust are automatically filtered, cutting media consumption by up to 40 %.
Environmental Dust Control
Standard pulse dust collectors keep workshop emission below 5 mg/m³. Dust‑free operation ensures compliance with ISO 14001 and local environmental inspections.
Minimal Civil‑Work Requirements
The integrated frame structure installs directly on flat workshop floors. Complex pit excavation or concrete foundations are not needed, shortening installation time by 60 %.
Scalable Customisation
Optional double‑hook configuration supports continuous production. Heavy‑duty hooks and enlarged chambers accommodate oversized weldments and high‑volume processing.

Frequently Asked Questions
Q: What kinds of workpieces are suitable for the blaster?
A: It is highly suitable for precision components, large‑size moulds, aluminum castings and irregular non‑stackable weldments. Single‑hook load capacity reaches 800 kg with maximum hanging dimension of φ1200×1800 mm.
Q: How many workpieces can be processed per hour?
A: Four to seven batches can be completed hourly with an 8‑15‑minute single‑batch cycle. Higher throughput is achievable for basic small‑size parts, delivering an effective processing area of 30‑50 m² per hour.
Q: Can hook lifting and rotation speeds be modified?
A: All motors are equipped with variable‑frequency drives. Higher rotation speed improves throughput for small parts and light rust, while lower speed extends blasting duration for heavy rust removal.
Q: What dust collector should be equipped for environmental‑protection purposes?
A: To meet industrial indoor emission standards, the system is compatible with MC pulse bag‑type or cartridge‑type dust collectors with 99.9 % filtration efficiency.
Q: How often should worn liners be replaced?
A: Depending on abrasive type and velocity, high‑manganese steel liners typically withstand 2,000‑3,000 blasting hours. Routine inspections during scheduled maintenance secure optimal performance.
Q: Can the blaster be integrated into automated production lines?
A: For seamless line integration, overhead monorail systems adopt PLC‑based handshaking protocols to coordinate with robotic loaders and automatic conveyors.
