In July 2020, our company shipped a 100-meter endless conveyor belt with a bandwidth of 1200mm to a cement plant in Oregon for the transportation and delivery of cement.

  The endless conveyor belt (ring conveyor belt) is a conveyor belt made into a jointless endless conveyor belt (ring conveyor belt) during the production process. Its characteristics are that the belt core has no joints, and the service life is not affected by early damage at the joints. 

  The surface of the belt is flat and the tension is uniform, so the belt runs smoothly and the elongation is small. The strength of the belt core joint can reach 90% of the strength of the belt body, and there is no obvious joint defect on the surface of the belt. 

  Therefore, the belt transportation is balanced. The belt core of the endless conveyor belt is made of high-quality cotton or woven cotton canvas, generally 2-6 layers or NN-200 nylon canvas (or polyester canvas) as the strength layer.

  The calculation method of the endless conveyor belt circumference are the same, including the common joint formula of endless conveyor belt: L=L (inner)+(n-1)S+1/2B(single belt) L=M[L (inner)+(n-1)S]+1/2B( multiple belts) in the formula, inner circumference of the endless conveyor belt (meter) B - width of the conveyor belt (meter) n - number of cloth layers s-length of each cloth layer (meter) M - number of connected conveyor belts. This is the basic operation, and it also needs to be combined with the actual type of ring belt products. There are certain differences.

  In a general speaking, the circumference of endless conveyor belt is usually based on the inner circumference. Due to the conveying equipment thickness degree is different, so we do not measure the outer circumference for all the time. The original length of the belt could be extended, then short the length of conveying equipment.

  Usually, when we measure the length of the belt, especially for the sidewall conveyor belt, we need to understand their sidewall height, base belt thickness, belt width. And confirm comprehensively, then to measure the circumference of the conveying equipment, although measure the circumference is easy, it is complicated to be used, need to combine our requirements to have a comprehensive choice.
