CE ISO High-performance Conveyor Pulley/ Middle Pulley/ Heavy Pulley for Belt Conveyor

LBHI Conveyor pulleys can be divided into three categories based on different load: light pulley, normal pulley and heavy pulley.

 -- Light Pulley: the shaft diameter is 80-100mm. The shaft and hub is single plate welded structure connected by single key, and the shaft can be extended outside the shell in one end.

--Middle Pulley: the shaft diameter is 120-220mm. The shaft and the hub are connected by keyless device.

-- Heavy Pulley: The shaft diameter is 200-400mm or larger. The shaft and the hub are connected by keyless device. The pulley is cast welded structure.

 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.
