What are the characteristics of belt conveyor

Belt conveyor is a kind of friction-driven machine for transporting materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler, drum, tensioning device, transmission device and so on.

The traction force of the ⑴ belt conveyor is transmitted by the friction between the transmission drum and the belt, so the belt must be tightened with a tension device to make the belt have a certain initial tension at the separation of the drum.

The ⑵ tape runs on the idler together with the cargo. The belt is not only a traction mechanism, but also a load-bearing mechanism. there is no relative movement between the load and the belt, which eliminates the friction resistance between the belt and the load in operation. Because the roller is equipped with a rolling bearing, there is rolling friction between the belt and the roller, so the running resistance is greatly reduced, thus the power consumption is reduced and the transportation distance is increased. For a belt conveyor, its traction transmission capacity is determined by the tension of the belt, the wrapping angle of the belt on the transmission drum and the friction coefficient between the belt and the transmission drum. To ensure that the belt of the belt conveyor does not skid on the transmission drum and run normally, corresponding measures should be taken according to different conditions in production practice. To improve the transmission ability of traction force, we can start from the following aspects:

⑴ increases the tension (initial tension). In the operation of the belt conveyor, the belt should be elongated, resulting in a decrease in traction, so according to the situation, the belt should be properly tightened by the tension device to increase the belt tension so as to improve the traction force.

⑵ increases the coefficient of friction. The specific measures are to protect the wood lining or rubber liner covered on the transmission drum to increase the friction coefficient, on the other hand to reduce the water and coal output and prevent the friction coefficient from decreasing.

⑶ increases the wrapping angle. Due to the poor working conditions and large traction force of the underground belt conveyor, double drum transmission is often used to increase the wrapping angle.

Belt conveyor is a kind of continuous transport equipment with traction, which is widely used in coal, metallurgy, mining, port, building materials, chemical, light industry, petroleum, transportation and other industries. It can be used to transport bulk, granular and bulk materials. According to the demand, you can find the relevant “belt conveyor manufacturer”.

Generally, the main parameters are determined according to the requirements of the material handling system, the various conditions of the material loading and unloading site, the relevant production process and the characteristics of the material.

1. Conveying capacity: the conveying capacity of conveyor equipment refers to the amount of materials transported per unit time. When conveying bulk materials, it is calculated on the basis of the mass or volume of materials transported per hour; when conveying items in pieces, it is calculated on the basis of the number of pieces transported per hour.

two。 Transport speed: increasing the conveying speed can improve the conveying capacity. When the conveyor belt is used as the traction part and the conveying length is larger, the conveying speed is increasing day by day. However, the high-speed belt conveyor should pay attention to vibration, noise, start-up, braking and other problems.

For the conveyor with the chain as the traction part, the conveying speed should not be too large to prevent the increase of dynamic load. At the same time, the conveying speed of the conveyor operated by the process shall be determined according to the requirements of the production process.

3. Component dimensions: the component dimensions of the conveyor include belt width, lath width, hopper volume, pipe diameter and container size, etc. The dimensions of these components directly affect the conveying capacity of the conveyor.

4. Conveying length and inclination angle: the length and inclination angle of the conveying line directly affect the total resistance and required power of the conveyor.
