Recently, we’ve noticed that many users know very little about conveyor belts—and even less about how to choose the right one. So let’s briefly walk you through some tips for selecting conveyor belt specifications and models based on different operating conditions:
1. Based on belt width, conveyor belts are classified into standard models such as B500, B600, B650, B800, B1000, B1200, and B1400 (where “B” denotes width in millimeters). Currently, Huaxia Rubber’s maximum production capacity is for conveyor belts with a width of B2700 mm.
2. Depending on the operating environment, conveyor belts are classified into types such as standard rubber belts, heat‑resistant rubber belts, cold‑resistant rubber belts, acid‑ and alkali‑resistant rubber belts, oil‑resistant rubber belts, and flame‑retardant belts (Huaxia’s flame‑retardant rubber belts have successfully passed both domestic coal‑safety certification and U.S. coal‑safety certification).
3. Based on belt tensile strength, conveyor belts are classified into standard‑strength and high‑strength types. Examples include standard canvas conveyor belts and high‑strength canvas conveyor belts; as well as standard steel‑cord core conveyor belts and high‑strength steel‑cord core conveyor belts. High‑strength canvas belts are further divided into nylon‑core (NN) belts and polyester‑core (EP) belts. Currently, Huaxia Rubber primarily produces high‑strength steel‑cord core conveyor belts, with the ST‑HHE lightweight, high‑strength steel‑cord core energy‑saving belt being its flagship product.
The ST‑HHE lightweight, high‑strength steel‑cord‑core energy‑saving conveyor belt is a high‑strength steel‑cord‑core conveyor developed independently by Huaxia Rubber. The application of ST‑HHE technology and products represents a technological revolution in the field of belt conveyors. According to statistics, while meeting all technical requirements—including conveying capacity, service life, and safety—the ST‑HHE belt conveyor system can reduce capital investment by more than 30% compared with conventional ST systems, and operating and maintenance costs by over 30%, with average electricity savings exceeding 26%.
