Sand Blasting Room

Sand Blasting Room – Industrial Surface‑Treatment System for Heavy‑Duty Applications

Sand Blasting Room, an industrial‑grade solution supplied by Botou Junda Machinery Equipment Co., Ltd., is designed for large‑scale surface‑treatment operations. Supported by our 3,000 m² production workshop and over 20 years of manufacturing experience, the products achieves a processing capacity of 2‑20 tons per hour with batch load capacity ranging from 1,000 kg to 20,000 kg. Each unit integrates pulse negative‑pressure dust‑collection system, wear‑resistant chamber structure and variable‑frequency travelling speed control, delivering 99.9 % filtration efficiency with outlet dust concentration below 10 mg/m³. Our fully‑enclosed room structure produces uniform surface profiles complying with ISO 8501‑1 standards for heavy‑industry applications, and supports combined installed power from 45 kW to 200 kW.

Why Choose Our Sand Blasting Room System

Addressing your surface‑treatment challenges requires robust equipment that balances environmental compliance and productivity. To minimise labour intensity while maintaining precise control over blasting parameters, our Sand Blasting Room combines a large internal working area with well‑engineered automated functions.

Equipped with variable‑frequency travelling mechanism, you can adjust moving speed according to workpiece dimensions and rust severity. Such adaptability balances cleaning performance and operational efficiency across diverse workload requirements and improves blasting throughput.

Inner chamber walls are lined with premium wear‑resistant plates to withstand continuous high‑velocity abrasive impact. Within harsh industrial environments, this construction greatly extends equipment service life and minimises maintenance downtime.

Technical Specifications

Core System Advantages

Enclosed Dust Removal for Environmental Protection

Your facility benefits from the combination of fully‑enclosed construction and pulse negative‑pressure dust‑removal technology. The system rapidly extracts operational dust during blasting cycles, ensuring emission levels meet strict environmental standards and preventing dust leakage into workshop areas.

Flexible Customisation Options

Chamber dimensions, gate configurations and automation levels can be adapted to your specific production requirements. Whether you need standalone operation or integration with existing coating production lines, our design team configures layouts matching your facility constraints and workflow patterns.

Automatic Abrasive Recovery

Integrated recovery and separation system automatically filters fractured grit and dust particles. Evenly‑distributed negative‑pressure air ducts combined with classifying separators maintain consistent abrasive quality while cutting consumable costs via efficient media recycling.

Application Scenarios

The Sand Blasting Room processes a wide range of workpieces including large steel structures, engineering machinery equipment, ship components and pressure vessels. It excels at surface rust removal, paint stripping and anti‑corrosion pre‑treatment for large castings, forgings and heavy‑duty equipment parts.

Industries such as power generation, metallurgy, chemical processing and mining rely on these chambers to prepare substrates requiring uniform surface profiles. Spacious interior accommodates over‑size pressure vessels and ship components that cannot be handled by conventional shot‑blasting equipment.

Frequently Asked Questions

Q: How do I choose between a sand blasting room and a shot‑blasting machine?

A: Select a Sand Blasting Room for extra‑large pressure vessels and ship components. Shot‑blasting machines are preferred for standard‑quality profiles with higher efficiency and lower abrasive consumption.

Q: Will abrasives clog the pneumatic recovery system?

A: Evenly‑distributed negative‑pressure air ducts together with classifying separators automatically filter broken grit and dust. Clogging rarely occurs under regular maintenance schedules.

Q: What complete supporting equipment is required?

A: Main chamber, recovery fan, pulse dust collector, blasting guns and high‑pressure hoses form the core system. A separate screw‑type air compressor is required as the power source.

Q: Can the dust emission meet national environmental standards after operation?

A: The industrial dust collector achieves 99.9 % efficiency with outlet dust concentration below 10 mg/m³, complying with domestic industrial regulations.

Q: What is the difference between mechanical recovery system and pneumatic recovery system?

A: Mechanical systems adopt screw or belt conveyors for high‑volume, heavy metallic abrasives. Pneumatic systems utilise vacuum suction, requiring less maintenance and shallower foundation for lighter media.

Q: How frequently should dust‑collector filter cartridges be replaced?

A: Replacement is generally determined by differential pressure gauge. Cartridges need replacing when ΔP exceeds 1,500 Pa despite pulse‑jet cleaning.
