I. Preventing Conveyor Belt Slippage
Slippage is often caused by insufficient tension, decreased friction coefficient, or overloading, easily leading to belt wear, motor overload, and even fire risks.
Effective Preventive Measures:
Regularly check the tensioning device to ensure the conveyor belt tension is appropriate, avoiding slackness due to aging and elongation;
Keep the contact surface between the drive roller and the conveyor belt dry and clean, preventing water, oil, or peat from reducing friction;
Control the load, strictly prohibit overloading starts, and use a slow start method when necessary to reduce impact;
Rosin powder can be blown into the rollers to increase friction, or replacing them with herringbone grooved rubber-coated rollers can increase the friction coefficient by up to 30%.
II. Preventing Conveyor Belt Deviation
Belt deviation is caused by installation errors, uneven material loading, or component malfunctions, and long-term operation can lead to problems such as tearing and material spillage.
Key Prevention and Control Measures:
Ensure that rollers and idlers are installed parallel, the frame structure is stable, and the center line is aligned;
Optimize the material drop point to ensure even distribution of material in the center of the belt, avoiding unilateral stress; Use self-aligning idler sets for automatic correction, especially suitable for long-distance conveyor lines;
Regularly clean adhering substances from the surfaces of rollers and idlers to prevent misalignment caused by uneven diameter.
III. Reduce Abnormal Wear and Structural Damage
Conveyor belt tearing and breakage often originate from foreign object jamming, poor joint quality, or overuse.
Protection Strategies:
Install metal detectors and foreign object removal devices at the feed inlet to prevent sharp objects from scratching the belt;
Strictly adhere to standards when manufacturing joints, use qualified conveyor belt buckles, and regularly check the joint condition;
Replace conveyor belts that are worn beyond limits, aged, or have reduced strength promptly, prioritizing flame-retardant and wear-resistant materials;
Install anti-tear protection devices to achieve early alarm and shutdown in case of malfunction.
IV. Strengthen Daily Inspection and System Maintenance
Establishing standardized operation and maintenance procedures is the foundation for ensuring the long-term stable operation of equipment.
Recommended actions:
Daily inspection of idler roller rotation for smooth operation, bearing noise for abnormalities, and motor current for normal operation;
Check the effectiveness of the sweeper function to prevent large materials from getting stuck in the rollers and causing slippage or damage;
Monitor motor temperature and voltage stability (power supply deviation not exceeding ±5%) to avoid electrical faults;
Strictly adhere to operating procedures, and prohibit operation of malfunctioning equipment or unauthorized operations (such as cleaning while running).
