Steel Core conveyor belt
FEATURES:
1. High tensile strength:Steel cord conveyor belt is suitable for large span,long distance transportation of materials
2. Small elongation in use:It need only a very short take-up stroke distance.
3. Small diameter of drive pulley:Steel cord conveyor belt body has a layer of longitudinally arranged steel cords as its skeleton,and thus is resistant to flex fatigue.Therefore,drive pulley of smaller diameter can be used to make the equipment smaller.
4.High adhesion between rubber and steel cord:The steel cords are coated with zinc on their surface,and also the rubber used has the property of qood adhesion with steel cords.Therefore,the rubber is tighrly adhered to the steel cords and is resistant to shock and difficult to drop,so the rubber belts are long in life.
