Coal Mining Belt Conveyor Guide Drum Bend Pulley

Driving pulley is the main part for transmiting the power,as per the diferent carying capacities,the drivingpulley can be divided into three categones:Light duty,meium duty and heavy duty,and for the same diameter ofthe puley,there are many different axle diameters and central spans.

The surface teatrment of the drving puley can be smooth steel,hering bone or rhombic rubber lagging,thesmooth steel pulley is available for the place which environment is small power,smal belt width and dry,theherring bone rubber lagging has a big friction facto,beter anti-slippery and drainage ability,but it has its owndirection,the rhombic rubber lagging is available for twoway operating conveyors,the vuicanized rubber laggedpulley are mesty used for important applicatons

Product Description

1, This series Drive rollers are welded by steel plate, and using rolling bearings.
2, The surface of drive plulley includes three type: smooth, plastic and cast plastic. Usually the smooth pulley can be used on condition that the power is not big, and the the ambient temperature is low. The plastic surface pulley should be used when it is easy to slip.
The quality of cast plastic pulley is better.Becasue the external surface layer is wear-resistant. The packed plastic drum can achieve the same performance. It's easy to replace rubber surface , easy to maintain.And it's also be considerde affordable and durable.
3, Please refer to the following table for each bandwidth of the roller.
4, The diameter selection of entire core plastic conveyor belt drive pulley is same as the same intensity rubber conveyor belt.

Product Paramenters

Advantage of pulley :

1. Dust-proof & Water-proof

The contact-sealing is adopted, which enjoys more superior dustproof and waterproof

2. Low Vibration and Noise

Static balance test to ensure G40 accuracy level.

3. Strong Force of Friction

The material for shaft is forged shaft of 40Cr instead of #45 round steel,which improves mechanical property

4. Easy Installation & Simple Maintenance

The bearing block and taper-lock are ground, which ensure the installation precision

5. Min 50000 hours service life

Stress annealing will be done after welding with CO2 gas shielded arc-welding machine, which can ensure the quality of welding line
