Are you looking for a reliable steel conveyor belt manufacturer in China for mining, coal transportation, cement production, or port material handling? Do you need a high-tensile steel cord conveyor belt that can handle heavy loads, long conveying distances, and demanding operating conditions? Or are you comparing Chinese factories for custom specifications, competitive factory-direct prices, and dependable bulk supply?
If so, China is a major sourcing destination for heavy-duty industrial conveyor belts, supported by established rubber processing, steel cord reinforcement, vulcanization, and quality testing capabilities. Steel cord conveyor belts use longitudinal steel wire ropes embedded in rubber to provide high tensile strength and low elongation, making them suitable for long-distance and high-capacity conveying. Below, we introduce five steel conveyor belt manufacturers in China, comparing their product ranges, manufacturing capabilities, technical characteristics, and target industries to help international buyers identify suitable suppliers.

Frequently Asked Questions
1. How do I choose the correct ST grade when replacing an existing steel cord conveyor belt?
Start with the original conveyor design documents and confirm the required belt strength, width, length, steel cord construction, and operating tension. ST ratings indicate nominal longitudinal tensile strength in N/mm, so ST2000 corresponds to a nominal tensile strength of 2,000 N/mm; however, this does not mean every belt with that rating has the same construction or performance. Ask the manufacturer to verify the existing specification against the conveyor's operating conditions before ordering, especially if the belt has been modified or the original records are incomplete.
2. Why does a steel cord conveyor belt splice fail even when the belt has the correct ST rating?
A correct ST rating does not guarantee a reliable splice. Failure can result from incorrect splice geometry, inadequate steel cord preparation, poor rubber bonding, unsuitable vulcanization temperature or pressure, or insufficient curing time. Before installation, request the splice design for the exact belt construction and confirm the required cord arrangement, splice length, bonding materials, and vulcanization procedure. During curing, record the actual temperature, pressure, and curing time, and inspect the finished splice before restarting the conveyor.
3. How do I check whether a steel cord conveyor belt will work with my existing pulley diameter?
Do not check the ST grade alone. Provide the manufacturer with the diameters of the drive and bend pulleys, the belt strength grade, steel cord construction, belt thickness, splice design, and the conveyor's operating conditions. Ask the manufacturer to confirm the minimum recommended pulley diameters for the proposed belt and splice configuration, using the relevant design standard or technical documentation. If the original equipment drawings are unavailable, measure the existing pulleys and collect the old belt specification before ordering. This helps reduce the risk of excessive bending strain, premature damage, or an unsuitable splice arrangement.
4. How can I reduce longitudinal tearing when conveying sharp rocks or oversized ore?
First, identify where and how the tear starts: inspect loading points, transfer chutes, trapped metal, and areas where oversized material can become lodged against the belt. Then evaluate whether the belt needs transverse reinforcement or a dedicated tear-resistant construction, in addition to an appropriate cover rubber grade. Increasing the ST rating alone does not necessarily prevent longitudinal tearing. Give the manufacturer details about the material's maximum lump size, sharpness, drop height, loading rate, and existing damage pattern so the proposed belt construction addresses the actual cause.
5. How do I determine whether a new steel cord conveyor belt is defective or the conveyor system is causing tracking problems?
Before blaming the belt, check whether the pulleys and idlers are aligned, the loading chute distributes material centrally, the take-up system applies suitable tension, and the splice is square to the belt edges. Record whether the belt tracks to one side when empty and when loaded, and whether the deviation occurs consistently at the same conveyor location. If the tracking problem persists after alignment and loading issues are corrected, document the belt dimensions, splice position, and deviation pattern and send them to the manufacturer for investigation. Do not assume that repeated mistracking automatically proves a manufacturing defect.
