The workshop has completed the mass production of high-quality belt conveyor idlers
At the critical stage of fulfilling orders for key domestic and overseas projects, a batch of idlers in the workshop of Shandong Shankuang Machinery Co., Ltd. have successfully completed the mass production task today. After undergoing rigorous verification of all indicators by the company's Testing Center, all products have met the qualification standards and been officially transferred to the next production stage. These idlers will provide guarantee of core supporting components for the complete machine assembly of belt conveyors, and fully boost the on-schedule implementation of related projects.
As the key supporting components for the operation of belt conveyors, the quality of idlers is directly related to the operational stability, conveying efficiency and service life of the equipment. The batch-produced idlers this time are high-quality products elaborately manufactured by Shandong Shankuang relying on the full-process automated production lines. From raw material selection to finished product roll-off, the enterprise has established a full-chain quality control system:
Special high-frequency welded pipes for idlers are adopted, featuring uniform wall thickness and high mechanical strength, which effectively enhance the overall load-bearing capacity of the idlers.
Equipped with double-sealed deep groove ball bearings, combined with labyrinth multi-layer sealing structure and food-grade lithium-based grease lubrication technology, an all-round protective barrier is built. Even under harsh working conditions such as damp and dusty underground mines and salt spray corrosion in ports, the idlers can still maintain stable operation and greatly extend their service life.
Meanwhile, the rotational resistance coefficient of the products is strictly controlled within 1.5N·m as specified in the national standard, which is better than the industry average level. This can significantly reduce the operational resistance and energy consumption of the conveyor belt, and cut down the equipment operation costs for users.
To ensure superior product quality, during the production process, Shandong Shankuang Testing Center uses professional equipment such as high-precision radial runout testers, idler flexibility test benches and axial movement measuring instruments to conduct full-index verification on each batch of idlers. Among them, the radial runout error is ≤0.3mm, the rotation time in flexibility test is ≥300s, and the axial movement is ≤0.5mm. All key parameters comply with the DTⅡ international standards and the industry specification GB/T 10595-2014 Belt Conveyors, which fundamentally ensures the safe and stable operation of belt conveyors, effectively reduces the wear rate of conveyor belts and prolongs the maintenance cycle of complete machines.
With years of deep cultivation in the idler manufacturing field, Shandong Shankuang has built a specialized idler production base equipped with multiple automated production lines, covering all processes including CNC cutting, precision welding, pressure assembly, automatic grease injection and finished product testing, with an annual production capacity of up to 500,000 units. The enterprise can mass-produce multi-series and multi-specification products such as trough idlers, parallel idlers, self-aligning idlers and buffer idlers, which are suitable for various belt conveyors with a belt width of 300mm-2200mm. These products are widely used in multiple fields such as mining, metallurgical smelting, port bulk cargo conveying and building material production.
The smooth production of this batch of idlers has been synchronously connected to the company's complete machine assembly line, laying a solid foundation for the subsequent assembly, commissioning and delivery of complete belt conveyor equipment. In the future, Shandong Shankuang will continue to uphold the philosophy of "Precision Manufacturing, Quality First", continuously optimize production processes and improve product performance, contribute high-quality core components to the high-quality development of the industry, and fully guarantee the fulfillment progress of key domestic and overseas projects.
