Belt line, also called conveyor, is a common material transport equipment. It is composed of conveyor belt, drive device, roller, bracket, tensioning device, belt protection device and other components. Belt line is widely used in mining, port, chemical industry, metallurgy, building materials, grain processing and other industries, is an indispensable part of modern industrial production. This paper will introduce the principle, classification and application of belt wire in detail.

First of all, let's look at how the belt wire works. The working principle of the belt line is to use the rotation of the driving roller to make the conveyor belt form a ring under the action of the tensioning device, so as to complete the conveying of materials. The conveyor belt is usually made of rubber or plastic, which has the characteristics of flexibility, wear resistance, high temperature resistance, etc., and can adapt to various working conditions. The driving device is usually an electric motor, which drives the operation of the conveyor belt through belt transmission or direct connection. Brackets and rollers are used to support and guide the conveyor belt to ensure its smooth operation. The role of the tensioning device is to maintain the appropriate tension of the conveyor belt and avoid problems caused by uneven tightness. The tape protection device is used to prevent material overflow or the intrusion of external dust.

According to the application scenario and the characteristics of the conveying material, the belt line can be divided into a variety of different types. For example, according to the transport capacity is divided into light, medium and heavy three; According to the working environment is divided into indoor and outdoor two kinds; According to the direction of transmission is divided into straight line and curve two kinds; According to the installation method is divided into fixed and adjustable two kinds; It is divided into short distance and long distance according to the conveying length. Different types of belt lines have their own advantages and characteristics in different fields, and can be selected and applied according to actual needs.

Belt wire has a wide range of applications in various industries. In the mining industry, the belt line can be used to transport ore, coal and other materials from the mine to the treatment plant or stacking area. In the port industry, belt lines can be used to transport bulk cargo from the dock to ships or warehouses. In the chemical industry, the belt line can be used to transport chemical raw materials or finished products. In the metallurgical industry, the belt line can be used to transport ore, coke and other materials. In the building materials industry, the belt line can be used to transport cement, sand and other materials. In the grain processing industry, the belt line can be used to transport grain, oil and other materials. In addition, the belt line is also widely used in cement, electric power, precision instruments and other industries.

As an important material transportation equipment, belt wire has many advantages. First of all, it can achieve continuous and efficient material handling and improve production efficiency. Secondly, the conveyor capacity of the belt line is relatively large, and it can adapt to the production needs of different scales. In addition, the operation of the belt line is relatively stable, the noise is low, and the interference to the working environment is small. In addition, the belt line also has the characteristics of simple structure and easy maintenance.

However, there are some limitations to the belt line. Because the conveyor belt is flexible, it is easy to slip or drift during long distance transportation or large Angle transportation. In addition, due to the limited length and height of the belt line, other types of conveying equipment need to be considered in some special occasions. In addition, the motor and mechanical equipment of the belt line have certain requirements for the adaptability of the environment, and corresponding protective measures need to be taken.

In summary, belt line is an important material transportation equipment, widely used in various industries. It delivers materials from the starting point to the end point in a continuous and efficient way, improving production efficiency and reducing the waste of manpower and resources. However, the belt line also has some limitations, which need to be selected and applied according to actual needs. With the progress of science and technology and the continuous improvement of production demand, I believe that the belt line will play a more important role in the future development.
