Summer Maintenance Plan for Conveyor Belt Systems in Industrial Concrete Batching Plants

Summer construction sites experience sustained high temperatures, posing a double challenge to the conveyor belt systems of ready-mixed concrete batching plants: prolonged exposure to sunlight and continuous high-load operation. Rubber conveyor belts are prone to surface cracking, hardening, aging, and wear under high temperatures. Simultaneously, issues such as thermal expansion of the conveyor belt, roller jamming, and tension imbalance frequently lead to conveyor belt misalignment, material spillage, and mixing machinery malfunctions.

This article analyzes the causes of conveyor belt failures in summer and proposes targeted operation and maintenance strategies to fundamentally prevent conveyor belt aging and misalignment.

• Thermal aging damage: Prolonged exposure to sunlight without shading can accelerate rubber aging by more than double.
• Tension mismatch: In high temperatures, the conveyor belt expands due to heat, resulting in excessive fixed tension and increased friction during operation.
• Idler malfunction: Dust adhesion and deterioration of high-temperature lubricating grease can cause idlers to jam, resulting in uneven stress on the conveyor belt.
• Unstable feeding: High-speed eccentric feeding impacts the conveyor belt, causing operational deviations.

• Install sunshades along the entire conveyor line to isolate direct sunlight and ultraviolet rays, effectively reducing heat aging damage.
• Regularly apply a high-temperature resistant rubber protectant to the conveyor belt surface to maintain rubber toughness and prevent cracking.
• Avoid prolonged high-speed, unloaded operation during the midday heat to reduce unnecessary belt friction losses.
• Select heat-resistant conveyor belts as permanent replacement parts for summer upgrades to adapt to long-term high-temperature operating environments.

• Dynamic Tension Adjustment: Appropriately reduce conveyor belt tension in hot weather, allowing for thermal expansion clearance to prevent excessive tension after thermal expansion.
• Regularly Clean Idler Rollers: Clean all idler rollers and remove dust and material residue daily to ensure flexible rotation and even force distribution.
• Install Automatic Deviation Correction Devices: Install electric deviation correctors on key sections of the conveyor, automatically resetting if belt deviation occurs.
• Optimize Feed Position: Ensure vertical, centered feeding to avoid belt misalignment caused by unilateral impact.
