Recently, we’ve noticed that many users have limited knowledge about conveyor belts, and even less understanding when it comes to selecting the right type. Here, we’ll briefly outline some key tips for choosing conveyor belt specifications and models based on different operating conditions:
1. **Width-Based Classification**: Conveyor belts are categorized by width into common models such as B500, B600, B650, B800, B1000, B1200, and B1400 (where “B” denotes width in millimeters). Currently, Huaxia Rubber’s maximum production capacity reaches conveyor belts with a width of 2700 mm.
2. **Environmental Resistance**: Depending on the operating environment, conveyor belts can be classified into types such as standard rubber belts, heat-resistant belts, cold-resistant belts, acid- and alkali-resistant belts, oil-resistant belts, and flame-retardant belts. (Huaxia Rubber’s flame-retardant belts have successfully passed both domestic coal safety certification and U.S. coal safety certification.)
3. **Tensile Strength**: Conveyor belts are further divided into standard‑strength and high‑strength varieties. Examples include standard canvas belts and high‑strength canvas belts; standard steel‑cord core belts and high‑strength steel‑cord core belts. High‑strength canvas belts are available in nylon (NN belts) and polyester (EP belts). At present, Huaxia Rubber primarily produces high‑strength steel‑cord core belts, with its ST‑HHE lightweight, high‑strength steel‑cord core energy‑saving belts taking center stage.
The ST‑HHE lightweight, high‑strength steel‑cord core energy‑saving belt is an independently developed product by Huaxia Rubber. The application of ST‑HHE technology and products represents a technological breakthrough in the field of belt conveyors. According to statistics, while fully meeting all technical requirements—including conveying capacity, service life, and safety—ST‑HHE belt conveyor systems can reduce equipment investment by more than 30% compared to traditional ST systems, and cut operation and maintenance costs by over 30%, with average electricity savings exceeding 26%.

Common Problems and Solutions in Conveyor Belt Operation
Belt slippage occurs due to reduced frictional traction at the pulleys, overload conditions, or belt jamming.
① After prolonged use, the belt elongates due to plastic deformation, resulting in insufficient tension, reduced frictional traction, and subsequent slippage.
② When the contact surface between the belt and the drive drum becomes contaminated with mud, water, or dust, the coefficient of friction drops sharply, leading to belt slippage.
③ Damage to idlers, entanglement with debris, or material buildup can cause many idlers to fail to rotate. Additionally, damaged belts or splice joints experience increased resistance as they pass over these idlers, causing severe belt misalignment. Overloading the conveyor also increases belt resistance, further contributing to slippage.
