- Product Description
Industrial Surface‑Treatment steel shot cleaning machine｜High‑Efficiency Automated Blasting Equipment
Botou Junda Machinery Equipment Co., Ltd. supplies enterprise‑grade steel shot cleaning machine systems specially designed for high‑volume industrial surface treatment. Drawing on 20 years of manufacturing experience and our 3,000 m² production facility, our equipment delivers processing capacity of 1‑15 tons per hour with installed power ranging from 37 kW to 160 kW. Our hook‑type systems handle workpieces from 500 kg up to 10,000 kg while maintaining hook rotation speed of 2‑4 r/min, ensuring consistent Sa2.5‑grade surface finishes for anti‑corrosion coating applications in metallurgy, construction‑machinery and heavy‑casting industries.
What Makes Our steel shot cleaning machine Systems Stand Out
Adopting centrifugal blast‑wheel technology, our cleaning machines propel steel media at velocities up to 60‑90 m/s. This dynamic energy efficiently removes welding slag, corrosion and mill scale even on complex geometries.
Thanks to multi‑wheel construction, steel plates, castings and structural parts can be processed continuously without manual intervention. Compared with pneumatic blasting technology, centrifugal systems consume less media and deliver higher throughput.
Blast wheels made of high‑chromium alloy produce uniform blast patterns and resist abrasive wear. Under normal production loads, this durability extends maintenance intervals to over 800 operating hours and minimises downtime.
Core Performance Features
Automated Abrasive‑Recovery System
Screw conveyors, bucket elevators and air separators are integrated into a closed‑loop circulation network. The 99.5 %‑efficient air‑wash separator automatically separates intact steel‑shot particles from dust and broken media. Abrasive consumption can be reduced by up to 40 % versus open‑loop systems.
Accurate Surface‑Profile Management
Surface roughness values between Ra 25 μm and Ra 100 μm can be achieved by adjusting blast‑wheel speed, exposure time and media size (S110 to S550 per SAE J444 standards). These adjustable anchor profiles guarantee optimal coating adhesion for industrial epoxy resins and marine‑grade paints.
Enclosed Wear‑Resistant Chamber Design
High‑manganese steel liners (60+ HRC hardness) protect critical chamber surfaces from continuous abrasive impact. Reinforced inlet and outlet seals prevent media leakage and maintain negative pressure with pulse‑jet cartridge dust collectors, ensuring workplace air quality meets emission standards below 50 mg/m³.
Adaptive Configurations for Workpiece Handling
Our steel shot cleaning machine product line includes monorail pass‑through systems for large‑structure manufacturing, roller‑conveyor types for continuous plate processing, and rotating‑hook models for irregular castings. Zero‑dead‑zone cleaning delivers full coverage while preventing impact‑related damage to precision components.

Industries Benefiting From Our Equipment
Shipbuilding & Heavy‑Duty Manufacturing
Remove mill scale from heavy plates and H‑beams prior to welding or painting. Our equipment delivers surface treatment complying with ISO 8501‑1 Sa2.5 requirements to ensure long‑term corrosion resistance under marine conditions.
Casting Operations
Eliminate ceramic shell residues and burnt‑on molding sand from engine blocks, pump housings and valve bodies. High‑intensity cleaning preserves dimensional tolerances when preparing surfaces for machining or assembly.
Automotive‑Component Manufacturing
Shot‑peen crankshafts, springs and gears to generate compressive‑stress layers. This procedure extends fatigue life by 200‑300 % for high‑cycle‑load applications such as suspension modules and transmission systems.

Frequently Asked Questions
Q: What impurities can the cleaning machine remove?
A: The system separates broken shot, dust, molding sand, rust scale and other contaminants from reusable steel media. This screening process preserves abrasive quality and guarantees consistent cleaning performance throughout production runs.
Q: What are the common types of cleaning machines?
A: Air separators and vibrating‑screen models are the most widespread, usually integrated directly into blasting equipment. High‑capacity production lines combine both separation methods for maximum screening accuracy and production efficiency.
Q: What damage may occur if steel shot is not cleaned and screened in a timely manner?
A: Contaminated abrasives accelerate wear on blast‑wheel blades and chamber liners. Accumulated dust clogs recovery pipelines, degrades surface‑cleaning quality and substantially increases media‑consumption rates.
Q: How is the machine installed within a complete production line?
A: Separators are normally positioned at the bucket‑elevator discharge point to remove waste while returning qualified shot to storage hoppers. This closed‑loop design maintains consistent media supply to blast wheels without manual intervention.
Q: How do I select the correct shot size for my application?
A: Small‑size media (S110‑S170) delivers finer surface finishes and higher coverage on thin‑walled parts. Larger shot (S390‑S550) efficiently removes heavy scale from thick sections. Refer to SAE J444 guidelines and your target Sa grade when selecting abrasive specifications.
