Conveyor Belt Fabric

- Jan 17, 2019-

The fabric core conveyor belt is set for conveying various special performance items and conveying core skeleton structure under different environmental conditions in different regions, mainly for cold, oil, heat, high temperature and chemical corrosion resistant conveyor belts. With core. It can be applied to different regions, different hot and cold conditions, as well as various foods such as food and food, chemical products and other bulk materials.


1. This product is made of cotton canvas (CC) or cotton-cotton interwoven dipped canvas (VC) by calendering, molding and vulcanization. 2, the product adapts to the requirements of different use conditions, can be made into edging type, open side type, middle ladder type, side ladder type and other different structural specifications (1) core material: polyester cotton interwoven fabric TC-70 type, full Cotton canvas CC-56 type (2) Bandwidth: 300mm-3000mm (3) Fabric layer: 1-12 layers (4) Covering rubber thickness: Working surface: 1.5-10mm Non-working surface: 0mm-6mm. The conveyor belt is made of a fiber fabric as a core, and is made of a general rubber as a covering material, and the surface is smooth and flat (Fig. 1. The core is a layered or integral fabric woven from fibers such as cotton, nylon, polyester or vinylon. Fiber is the earliest core material used, easy to bond with rubber. The strength is slightly improved in wet state, but the breaking strength is low (mostly around 56 N/(mm·layer)). The anti-corrosion and mildew resistance is poor, and the use is decreasing. In the late 1950s, nylon fiber fabrics were used as the core material, and it has become the largest amount. The nylon fiber has a strength of up to 700 N/m2, which is resistant to water, corrosion and bending fatigue; Larger. The properties of polyester fiber are similar to those of nylon fiber, and the elastic elongation is only half of that of nylon fiber. It is a promising material. Vinylon fiber strength is 200 N/m2, elastic stretch Longer than nylon fiber, easy to bond with rubber, good heat resistance, but the strength is reduced by 10~25% in wet state, only in a few countries such as China, Japan, etc. Only one fiber can be used when braiding the core , also available in two types of fiber Dimensional blending or interweaving. 3. Ordinary conveyor belt is widely used in building materials, chemical industry, coal, electric power, metallurgy and other departments. It is suitable for conveying non-corrosive non-stinging block, granular and powder materials at room temperature, such as Coal, coke, gravel, cement and other bulk materials (materials) or pieces, transporting bulk materials with bulk density of 6.5~2.5t/m3, such as bulk, granular, powder, etc., can also be used for the transportation of adult goods. 


The choice of conveyor belt needs to consider various factors, mainly: the relevant requirements of the conveyor system for the conveyor belt; the terrain environmental conditions and safety requirements; the type, shape, granularity and characteristics of the transported materials, whether there is heat and chemical Function; requires maximum bandwidth, working tension and conveying capacity; minimum diameter of drum; groove and lateral stiffness; load support; length of curve section and transition section; tensioning method and stroke; receiving point and receiving condition. And the running cycle of the conveyor belt: impact resistance and tear resistance requirements; joint conditions.


1 short-distance belt conveyor, polyester fabric core conveyor belt should be used. For belt conveyors with large conveying capacity, long transportation distance, high lifting height and large tension, steel cord conveyor belts should be used.

2 The material to be conveyed contains a large block material. When the direct drop of the receiving point is large, an impact-resistant and tear-proof conveyor should be used.

3 The maximum number of layers of the layered fabric core conveyor belt should not exceed 6 layers: when the material to be conveyed has special requirements on the thickness of the conveyor belt, it can be appropriately increased.

4 The downhole belt conveyor must use a flame-retardant conveyor belt.
