Roller Conveyor Blaster

Roller Conveyor Blaster – Industrial Automated Blast System for Sa2.5 Surface Preparation of Steel Structures

Roller Conveyor Blaster is an industrial‑grade automated shot blasting system developed by Botou Junda Machinery Equipment Co., Ltd., specially designed for high‑volume steel structure surface treatment. Drawing on 20‑year casting technology expertise and a 3,000 m² manufacturing workshop, the system processes workpieces up to 2000 × 1000 mm at a conveying speed of 0.5‑2.5 m/min, delivering a cleaning capacity of 120‑180 m²/h. Equipped with four 15 kW blast turbines and a roller system rated at 1.5 t/m load capacity, it removes mill scale, welding slag and rust in one pass to achieve Sa2.5 surface standard. It serves global steel manufacturing, shipbuilding and infrastructure industries.

Why Choose Our Roller Conveyor Blaster for Heavy‑Duty Applications

Consistent surface quality and zero production bottlenecks are critical to your steel manufacturing workflow. Conventional manual blasting suffers from low labour efficiency and uneven surface finish. The automatic continuous‑processing design of Roller Conveyor Blaster solves these pain points.

Four strategically positioned blast turbines deliver 360‑degree coverage. Conveyor speed is adjustable from 0.5 to 2.5 m/min to completely remove heavy rust and mill scale. Thanks to this flexibility, you can increase speed for light‑duty cleaning or reduce speed for heavily rusted surfaces.

Built with heavy‑duty welded frame and high‑manganese steel liners, the machine withstands long‑term operation under severe abrasive impact. The segmented independent drive system consumes less power under partial‑load conditions to cut your operational costs.

Technical Specifications

Core Advantages for Your Production Line

Four‑Sided Simultaneous Blasting: Multiple turbines arranged around the conveyor path ensure uniform treatment on all exposed surfaces. Welding slag and heavy rust are eliminated in one single pass with no manual touch‑up required.

Heavy‑Duty Roller System: 1.5 t/m rated load transports thick steel plates and H‑beams without deformation. Your structural components maintain dimensional accuracy throughout the cleaning cycle.

Variable‑Speed Control: Adjust conveyor speed according to rust severity. Lower speed extends exposure time for thorough cleaning of heavily corroded parts; higher speed boosts throughput for lightly rusted materials.

Efficient Abrasive Recovery: Integrated air separator and double‑layer wear‑resistant curtains minimise steel shot loss. Full‑bottom screw recovery system efficiently collects spent abrasives to lower operating costs.

Production‑Line Integration: Retractable front and rear rollers connect directly to cutting lines and painting lines. Rigid welded frame maintains alignment under continuous heavy loads for extended service life.

How Roller Conveyor Blaster Transforms Your Surface Preparation Process

Roller Conveyor Blaster automates previously labour‑intensive tasks with inconsistent results. Workpieces travel through inlet transition rollers into the blast chamber, where high‑velocity abrasive particles instantly strike all exposed surfaces.

The pulse dust collector captures airborne particles by maintaining negative pressure inside the chamber before they escape. No intermediate storage delay between cycles; cleaned parts can go straight to coating application.

Conventional batch processing that causes production downtime is replaced by this continuous workflow. Instead of performing hazardous manual blasting, your operators focus on raw‑material loading and system performance monitoring.

Frequently Asked Questions

Q: What is the maximum workpiece size and hourly throughput of this roller conveyor blaster?

A: With roller load capacity of 1.5 t/m, the machine handles workpieces up to 2000 mm wide and 1000 mm high. It delivers cleaning output of 120‑180 m²/h, equivalent to 8‑12 tons per hour, meeting high‑volume processing demands for medium‑sized steel mills.

Q: What about energy consumption and total installed power?

A: Total installed power is approximately 90 kW, including all auxiliary units and four 15 kW blast turbines. Its modular independent unit architecture allows partial shutdown under moderate loads to reduce energy costs without compromising cleaning quality.

Q: Can conveyor speed be modified for different rust levels?

A: Speed is infinitely variable within 0.5‑2.5 m/min. Run slower for heavily scaled components requiring thorough cleaning; increase speed for lightly rusted parts to improve productivity.

Q: How often do wear‑resistant liners need replacement?

A: High‑manganese liners typically last 1,500‑2,000 blasting hours, depending on abrasive hardness and turbine operating speed.

Q: How does the system manage dust control?

A: It adopts a multi‑stage pulse‑jet cartridge filter system. Negative pressure inside the blast room prevents dust leakage into the workshop while complying with exhaust emission standards.
