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.

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
