30000-Hour Conveyor Pulley/ Rubber-lagged Pulley/ Heavy Pulley for Belt Conveyor
For Heavy Pulley and Middle Pulley, The rubber-lagged pulley can effectively improve the operating condition of belt conveyors, protecting the steel pulley from abrasion; with the diamond-pattern or herringbone-pattern rubber lagging, it can increase the surface friction of conveyor, effectively avoid the sliding friction between the conveyor pulley and rubber belt, reducing the belt slip and material cementation on the pulley surface and thus reduce the belt off tracking and abrasion, making the rubber-lagged pulley and belt rotate in-phase, and guarantee that High-performance and large capacity belt conveyor is in good working conditions.
1,Middle and heavy pulleys will be inspected with static analysis and Three-dimension finite element analysis software, which strictly ensure the quality;
2,the material for shell is 16Mn of more superior performance instead of Q235, which ensures shell quality and performance, whose content of S and P ensures welding quality;
3,the material for shaft is forged shaft of 40Cr instead of #45 round steel,which improves mechanical property;
4,the bearing block and taper-lock are ground, which ensure the installation precision;
5,the welding line and shaft are inspected by NDT and the shaft will be tested three times, which can ensure the quality of shaft and welding line;
6,stress annealing will be done after welding with CO2 gas shielded arc-welding machine, which can ensure the quality of welding line;
7,the contact-sealing is adopted, which enjoys more superior dustproof and waterproof;
8,Static balance test will be done for pulleys according to GB10595-2009, which reaches the precision class of G40.
We own complete manufacture lines, including the cutting of all parts, rough and elaborate processing, fitting-up and whole-set assembly.
There are more than 800 employees in total, including 244 engineers. Among these technical staff, 109 R&D personnel for engineering departments, 66 sales engineers for sales department and 69 welding engineers, Equipment engineers,Process engineers and QC engineers for producing department.
