ST630-ST5400 Coal mine steel cord rubber conveyor belt with anti fire feature
Structure: The belt core is comprised of longitudinally and evenly arranged non-spinning galvanized wire ropes and high adhesive core rubber, with the upper side and lower side covered with rubber layer.
Features of flame retardant steel cord conveyor belt:
Allow the use of high strength, high safely coefficient; elongation minima, tension travel a short distance; minimal tension elongation, travel a short distance; Steel wire rope and rubber combined with a solid, excellent dynamic performance; the belt body is soft, into a good grove, linear operation is good; excellent shock resistance; joint reliability, long service life.
Specification:
Tensile strength: 630N/mm~5400N/mm
Width:800mm~2200mm
