Steel cord conveyor belt
Steel cord conveyor belt
Belt strength(ST_NO. ): ST_630~ST_5400
Belt width(mm): 600~2600
1. Usage
Steel cord conveyor belts are widely used in high strength, long distance and heavy load than sportation of materials, and they are also used in high strength and distance transportation of materials on special occasions.
2. Characteristic
(1)High tensile strength: The belts are suitable for large span, long distance transportation of materials.
(2)Small elongation in use: The belts need only a very short take-up stroke distance.
(3)Small diameter of drive pulley: The bell body has a layer of longitudinally arranged steel cords as its skeleton, and thus is flexble and fatigue - resistant. Therefore, drive pulley of smaller diameter can be used to make the equipment smaller.
(4)High adhension between rubber and steel cord: The steel cords are coated with zinc on their surface, and also the rubber has the property of good adhesion with steel cords. Therefoe the rubber is tightly adhered to the steel cords that is shock resistant and hard to peel off, which make the belt long life.
(5)Even tension of steel cords: Out of our advanced techniques in manufacturing, the steel cords are very equably arranged and have the same tension, so the velts are well balanced in tunning and diffcult to run away.
(6)Good troughability: As the belt body has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from eacaping.
(7)Inspection of the belt with X-rays: Users can use X-rays to inspect damages of the skeleton, the steel cords on the conveyor machines to prevent accidents.
用途：
适用于煤矿、矿山、港口、 电力、冶金、 建材等行业要求防撕裂条件的物料输送，具有拉伸强度大、寿命长、使用伸长小、成槽性好。耐曲挠性好。可用于长距离、大跨度、大运呈和高速度物料的输送。
Use: be widely used in antitearing condition, such as coal, mine, harbour, power station, metallurgy, biulding etc. strong tensile strength, long elongation, long life, easy to trough, anti-bent. Can convey materials at long distance, big span, big capacity and high speed
