1.   Product Introduction of Pulley for belt conveyor

Pulleys are important components for belt conveyors.In order to meet the requirements of long-distance
high-speed large-capacity belt conveyors, LIBO adopts advanced finite element method, good-quality
material, optimized technical process and large high-precision machines to produce good-quality and
long-life pulleys. 

Technical feature of Conveyor pulley

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;
