The conveying method of the rubber conveyor belt depends on the conveying capacity of the conveyor belt and will be restricted by terrain and environmental protection conditions. It is the prerequisite for determining the carcass material, structure, safety factor, and conveyor belt length for heavy-duty rubber conveyor belts. The rubber conveyor belt has the characteristics of heat-resistant belt, wear-resistant belt, fire-resistant belt, oil-resistant belt, alkali-resistant belt, acid-resistant belt, heat-resistant belt, and cold-resistant belt. It is mainly used for the transportation of solid materials in various mining, metallurgy, steel, coal, hydropower, building materials, chemical, food, and other enterprises.
Selection of carcass material and structure of rubber conveyor belt:
The performance of the conveyor belt is closely related to the material, structure, and number of layers of the belt core. The multi-layer cotton canvas belt has low strength, many layers, is not fatigue resistant, easy to mold, heavy-weight, and high energy consumption;
Nylon belts have high strength, great elasticity, lightweight, good impact resistance and bending resistance, good trough forming performance, mildew resistance, water resistance, and other properties that are better than cotton canvas conveyor belts. The disadvantage is that the elongation is large. When the tensioning stroke can be set to be longer, the nylon rubber belt can be preferred;
The strength of the polyester belt is similar to that of nylon. It has all the advantages of a nylon conveyor belt. Its elastic modulus is higher than nylon, its elongation is small, and its dimension is stable. It is an ideal transportation belt commonly used in industry.
The steel cord conveyor belt has high strength, good trough ability, small elongation, and short tensioning stroke. It is especially suitable for the transportation requirements of large transportation volume, high belt speed, and long-distance.
From the structural point of view, the rubber conveyor belt is mainly composed of three parts: carcass material, cover layer, and skim rubber material. The covering layer is a key part that determines its performance and use. According to the different materials used in the cover layer, the conveyor belt industry can be divided into two categories: heavy conveyor belts and light conveyor belts. The former uses rubber (including natural rubber and synthetic rubber) as the main raw material, so it is also called rubber conveyor belts. The scope is concentrated in the fields of heavy industry and infrastructure construction; the latter mainly uses polymer materials, which are mainly used in light industries such as food and electronics.
Cover rubber selection:

The choice of cover layer includes covering material, surface morphology, and thickness. The main components of the covering layer are various rubbers and plastics. Since the properties of various rubbers vary greatly, such as natural rubber and styrene-butadiene rubber have good abrasion resistance, ethylene-propylene rubber is particularly heat-resistant, but cyanide rubber has good oil resistance, and propylene butyl rubber is both heat-resistant and oxidation-resistant. Therefore, the choice of the type of covering material must be comprehensively considered according to the types of commonly used conveying materials, operating conditions, and working environment.
Besides, the increase in the thickness of the covering layer is also conducive to improving the impact resistance and abrasion resistance of the rubber conveyor belt. Especially nowadays, the cotton canvas belt core has been replaced by a synthetic fiber fabric belt core. The performance of the belt core has been greatly improved, while the thickness is relatively reduced. To improve the overall performance of the belt, it is necessary to increase the thickness of the covering layer to give full play to its advantages and increase the service life of the conveyor belt. However, if the lower covering layer is too thick, the running resistance of the conveyor belt will increase.

The advantages and classification of nylon conveyor belts for mobile conveyors. The scope of use of nylon loading conveyor belts is also quite extensive. Among the customers who come to our factory for custom conveyors, there are also a considerable number of customized nylon conveyor belts. This is all due to the fact that nylon conveyor belts are better than other conveyor belts. Irreplaceable advantages and its disadvantages; This is the first time we know about nylon conveyor belts. The simplest understanding is just as the name suggests because the middle interlayer canvas is nylon canvas. So it is called nylon conveyor belt. Nylon conveyor belt is made of nylon canvas after calendering, forming, vulcanizing and other processes. Nylon loading conveyor belt has the characteristics of thin belt body, high strength, impact resistance, good groove formation, large interlayer adhesion, excellent flexibility and long service life. It is suitable for medium and long distances, high load capacity, and high speed conditions. Conveying materials under the belt, so its application is quite extensive. Nylon conveyor belts are widely used in mining, coal yard, chemical industry, metallurgy, construction, port and other sectors in our country. Nylon conveyor belts are suitable for conveying various materials such as coal, coke, sand, gravel, cement and other bulk materials (materials) or finished items, which are non-corrosive and non-spike-free block, granular, and powder materials at room temperature. Bulk, granular, powder and other loose materials can also be used to transport adult goods. Compared with ordinary cotton core conveyor belt, it has the advantages of high strength, good elasticity, impact resistance, light weight, and good groove forming ability. It can effectively reduce the transportation cost and realize high-speed, large-span, and long-distance transportation. The belt has good elasticity, impact resistance and abrasion resistance. Good flexibility, easy to groove. No mildew occurs. The belt is thin, light weight, good elasticity, impact resistance, high adhesion strength, good performance, interlayer adhesion, high strength, the strength of nylon canvas is about 2.5-9 times that of cotton canvas, excellent flexibility and long service life It is suitable for conveying materials under medium and long distance, high load capacity and high speed conditions. Nylon conveyor belts do not bear the force very well, but the friction is relatively good, the price is the cheapest, but the loss is the largest, the most easily worn rubber conveyor belt is strong, the friction is almost the same, there are points, there are ordinary PVC or rubber General workers' PVC rubber conveyor belt with steel wire is a very common one. The force is average, but common. So, what are the general categories of nylon belts? (1) According to the performance of the covering rubber, it can be divided into cold-resistant type, acid-base-resistant type, oil-resistant type, abrasion-resistant type, heat-resistant type, flame-retardant type, etc. (2) According to different purposes, it can be divided into lifting belt, power belt and loading conveyor belt. (3) According to the different structure, it can be divided into ordinary laminated type, impact-resistant and tear-resistant type with transverse reinforcement layer. (4) According to the performance of the covering rubber, it can be divided into ordinary type, flame retardant type, cold resistant type, acid and alkali resistant type, oil resistant type, etc. Our company is a high-tech enterprise specializing in mobile conveyors.
