Proper operation of a belt conveyor requires attention to equipment inspection, operating procedures, shutdown maintenance, and emergency response. Following these procedures helps reduce equipment failures, prevent damage to conveyor components, and maintain a safe working environment.
Pre-start inspection
Before starting the conveyor, operators should inspect the belt, rollers, drive system, and safety devices to make sure the equipment is in normal working condition.
The main inspection points include:
Check the conveyor belt: Inspect the belt for cracks, delamination, and excessive wear. Damaged belt sections should be addressed before operation.
Inspect idlers and drive pulleys: Check for worn or damaged components, restricted rotation, or other abnormalities that could affect belt movement.
Check safety and tensioning devices: Confirm that the braking system and belt tensioning device are functioning properly.
Inspect electrical connections: Check the electrical wiring and emergency stop buttons for loose connections or signs of malfunction.
Check the materials to be conveyed: Remove sharp metal objects and oversized or excessively heavy items that could become trapped in the conveyor or damage its components during startup.
Operating procedures during conveyor operation
Before starting the conveyor, operators should activate the audible and visual warning signals. The equipment should only be started after confirming that no personnel are in the operating area.
During operation, the following precautions should be observed:
Keep clear of moving components: Never touch the moving conveyor belt, pulleys, rollers, or other rotating components with hands or tools. Do not cross over the conveyor or stand on it while it is operating.
Avoid overloading: Keep the material load within the conveyor's rated capacity. Excessive loading can cause belt slippage and motor overheating or overloading.
Monitor equipment conditions: Listen for unusual operating noises and observe motor temperature during operation. Stop the conveyor immediately if abnormal conditions are detected and inspect the equipment.
Correct belt misalignment properly: If the belt moves away from its normal running path, adjust the idler angle or tensioning device as required. Never attempt to pull the moving belt back into position by hand.
Shutdown and post-operation maintenance
The correct shutdown sequence helps prevent material accumulation and reduces unnecessary wear on conveyor components.
Operators should follow these steps:
Stop material feeding first: Stop the upstream feeding process before shutting down the conveyor. Allow all remaining material on the belt to reach the discharge point before stopping the main drive.
Clean the conveyor: Remove residual materials from the area around the conveyor, as well as from idlers and pulleys. This helps prevent material buildup, corrosion, and component jamming.
Record operating abnormalities: Document any unusual conditions observed during operation and update the equipment maintenance records for subsequent inspection and servicing.
Disconnect the power supply: After shutdown, disconnect the main power supply and lock the electrical control cabinet to prevent unauthorized or accidental startup.
Emergency response and fault handling
Belt slippage, belt tearing, and material blockages can interrupt conveyor operation and create safety risks. Operators should respond promptly and follow the appropriate shutdown procedures.
Stop the conveyor immediately: When belt slippage, tearing, or jamming occurs, press the emergency stop button and disconnect the main power supply. Never attempt to repair a fault by hand while the conveyor is running.
Remove blocked materials safely: Before clearing trapped or accumulated materials, stop the conveyor and disconnect the power supply. Cleaning or removing blockages while the equipment is operating is strictly prohibited.
Respond to personnel entrapment: If a person becomes trapped in the conveyor, activate the emergency stop immediately and contact emergency rescue services. Do not attempt to pull the trapped person out without proper assessment and assistance, as this could cause further injury.
Custom machining of belt conveyor components
Regular inspection and maintenance are important for belt conveyor operation, and the condition of mechanical components also affects equipment reliability. Shafts, pulley components, connecting parts, and support structures may require replacement or custom machining when standard parts do not meet specific equipment requirements.
We provide single-piece and small-batch precision machining according to customer-supplied drawings and dimensional specifications. Hansheng Automation supports drawing-based manufacturing of non-standard mechanical components for conveying equipment and other industrial machinery.
Our precision machining services also cover components for other industries, including functional parts for tobacco packaging and filling machinery, precision structural components for yacht equipment, and mechanical parts for RC racing cars. These components can be manufactured according to customer drawings and specific machining requirements.
