Workpiece Conveyor

The workpiece conveyor is an integral component of a shot blasting machine, responsible for moving parts or materials through the machine's blasting zone at a controlled speed. It ensures consistent exposure of all workpiece surfaces to the abrasive media, enabling uniform cleaning, descaling, or surface preparation. Its design varies based on the shape and size of the workpieces, such as using roller conveyors for flat plates, belt conveyors for small parts, or chain-driven systems for heavy castings. The conveyor system is typically powered by an electric motor via gear reducers, moving workpieces along a predefined path through the shot blasting chamber. As the workpiece travels, it is bombarded by high-velocity abrasive particles propelled by a wheelblast or airblast system. The conveyor speed is adjustable to control the duration of blasting, directly affecting the intensity of surface treatment. It often works in synchronization with the abrasive recycling and dust collection systems to maintain continuous operation. The conveyor is available in various configurations to suit different workpiece types and production requirements. Key parameters include conveying speed (0.5–5 m/min), workpiece load capacity (500–2000 kg/m), conveyor width (600–1500 mm), conveyor length (3000–12000 mm), drive motor power (1.5–7.5 kW), speed control accuracy (±0.1 m/min), operating temperature (-10–60 °C), ingress protection (IP54–IP65), conveyor chain material (40Cr–42CrMo), frame material (Q235–Q345), noise level (75–85 dB(A) at 1 m), and weight (1500–8000 kg). Materials used include carbon steel, abrasion-resistant steel (e.g., AR400), rubber for belts, and polyurethane for wear liners. These values are reference ranges and must be verified with the manufacturer for specific models and applications. The conveyor is designed for integration into shot blasting machines and must be selected based on workpiece dimensions, weight, and required throughput. Proper installation and maintenance are essential for reliable operation and consistent surface treatment results.
