30000h Conveyor Pulley, Heavy Pulley, Ceramics-lagged Pulley for Conveyor system

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.

Compared with common pulleys, Ceramics-lagged pulley enjoys higher friction factor, so conveyor belt of less strength can be selected, and equipment cost can be reduced greatly; Moreover, with ceramic chip fixed into the rubber by hot vulcanization, the service life of pulleys can be prolonged; the groove between ceramic chips make it easy to remove water and sludge, so this kind of pulley can work well in bad conditions.

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.
