CONTITECH has developed the steel cable conveyor belt Stahlcord® Barrier for less conveyor belt damage and a long service life in opencast mining. With its new sturdy steel transverse reinforcement in the top cover, the conveyor belt is two to three times more resistant to impact breaks than conventional steel cord conveyor belts without transverse reinforcement. ¨These properties make the belt ideal for transporting coarse and sharp-edged materials in opencast mining,¨ pointed out Dr Andrey Minkin, Application Engineer, ContiTech Conveyor Belt Group.
The rough working conditions in opencast mining place high demands on steel cord conveyor belts. Impact breaks occur on the conveyor belts time and again, causing damage to the steel cords in the belts. So-called transverse reinforcements offer more safety and stability. The Stahlcord« Barrier is a steel cord conveyor belt with a rubber surface on the top cover, in which thin steel cords run closely together at right angles to the direction of travel of the conveyor belt. They protect the steel cords in the belt carcass and prevent impact breaks and longitudinal slitting in the conveyor belt.
