Primary polyurethane cleaner is installed on the surface of discharge pulley, with scraper pressing the belt at certain angle and pressure. As the first stage of multistage cleaning system, the primary polyurethane cleaner can clear away most of the sticky material on the belt, only a layer of sticky power left. Unique design of this kind of belt cleaner can provide simple installation and maintenance and low cost, prolonging belt service life.

Feature

1.Middle and heavy conveyor pulleys will be inspected with static analysis and Three-dimension finite element analysis software, which strictly ensure the quality;

2.the material of conveyor pulley 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 conveyor pulley according to GB10595-2009, which reaches the precision class of G40.
