China-supplied Conveyor Pulley/ Bend Pulley/ Head pulley for belt conveyor

  Conveyor Pulleys are important components for belt conveyors. In order to meet the requirements of long-distance high-speed large-capacity belt conveyor, 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

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 two 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.
