A conveyor belt, also called a conveyor belt, is a rubber, fiber, metal compound, or a compound of plastic and fabric, which is used to carry and transport materials in a belt conveyor. Belt conveyer is widely used in agriculture, industrial and mining enterprises and transportation and transportation industry to transport various solid and powder materials or parts. It can be used continuously, high efficiency and big angle transportation. It is safe to operate, easy to use, easy to repair and low in freight. It can also shorten transportation distance, reduce project cost and save manpower. Physical strength.
There are many types of conveyer belts. According to their use, they are: ordinary use belt, flame retardant and antistatic conveyor belt, general refractory conveyor belt, heat-resistant conveyor belt, high temperature resistant conveyor belt, acid alkali resistant conveyor belt, oil resistant belt, cold resistant conveyor belt and so on.
According to the classification of structural materials, there are ordinary cotton canvas conveyor belt, nylon conveyor belt, polyester conveyor belt, wire rope core conveyor belt, PVC core conveyor belt, PVG core conveyor belt, steel cable conveyor belt, etc.
According to the classification of product structure, there are stratified conveyor belt, whole core conveyor belt, wire rope core conveyor belt, steel cable conveyor belt, tubular conveyer belt, pattern conveyer belt, belt conveyor belt, layer reducing conveyor belt and so on.
For convenience, we usually use a unified representation to represent all kinds of conveyor belts.
1. The common representation method of stratified conveyer belt (standard representation method and this is different, please refer to the standard GB7984): take NN200 1000 x 6 (6 +3) as an example: NN200- represents nylon 200, 1000- indicates the width of the band, 6- indicates the number of nylon cloth layers, (6 +3) - 6 milli of the upper and lower covers of the conveyor belt, respectively. Rice and 3 mm thick.
2, the common representation method of wire rope core conveyer belt: take ST1000 H 1000 4.0-6.0-6.0 as an example: ST1000- represents the strength specification, 1000N/mm H- indicates the width of the product expressed by the performance level 1000- of the covering glue, the unit mm diameter 4.0- represents the diameter of the wire rope, and the unit mm 6.0-6.0- indicates the upper and lower coverage. Thickness of glue, unit mm
3, the whole core conveyor belt representation method: general coal mine PVC and PVG full core flame retardant conveyor belt with strength grade and belt width to express.
The intensity level is generally divided into 4, 5, 6, 7, 8, 9, 10, 11 and the highest to 16. The corresponding intensity is 680S, 800S, 1000S, 1250S, 1400S, 1600S, 1800S, 2000S, 2240S, 2500s, 2800S, 3100S, and.
The width of the conveyor belt is generally 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm and so on.
China stipulates that all the conveyor belts used in underground coal mines must be fire-resistant and anti-static conveyor belts that meet our relevant standards. Nowadays, the commonly used transportation of coal mine enterprises is: PVC whole core flame retardant antistatic conveyor belt, PVG whole core flame retardant antistatic conveyor belt, wire rope core flame retardant antistatic conveyor belt.
The flame retardant and antistatic conveyor belt mainly stipulates the safety performance of the product: 1, the alcohol spray lamp burning; 2, the surface resistance; 3, the roller friction; 4, the simulated laneway propane combustion. These inspection items represent the safety performance of products.
