What Is a Powder Conveyor?

The stone powder conveyor uses a motor as a power source, and conveys the stone powder through a conveyor belt. The stone powder conveyor is mainly composed of a frame, a conveyor belt, a belt roller, a tensioning device, and a transmission device. In mining engineering, stone powder conveyors are widely used. ^[1]

The belt type stone powder conveyor is composed of a driving device tensioning device, a middle frame of the conveyor belt and a supporting roller as a traction and load bearing member, so as to continuously transport loose materials or pieces. Belt stone powder conveyor is a friction-driven machine that transports materials in a continuous manner. Using it, the material can be formed on a certain conveyor line from the initial feeding point to the final unloading point. It can be used for conveying both broken materials and pieces. In addition to pure material transportation, it can also be matched with the technological requirements in the production process of various industrial enterprises to form a rhythmic flow line. Therefore, the belt stone powder conveyor is widely used in various modern industrial enterprises. Belt conveyors are widely used in mines' underground roadways, mine ground transportation systems, open-pit mining sites and beneficiation plants. It is used for horizontal or inclined transportation. ^[1]

(1) Start and stop

Stone powder conveyors should generally be started under no-load conditions. When several belt stone powder conveyors are installed in sequence, a starting device that can be locked should be used to start and stop in a certain order through the centralized control room. In addition, in order to prevent unexpected accidents, each stone powder conveyor should also be provided with a button to start or stop on the spot, which can be stopped independently. In order to prevent the conveyor belt from being torn longitudinally for some reason, when the stone powder conveyor length exceeds 30m, a stop button should be installed at a certain distance (such as 25-30m) along the entire length of the stone powder conveyor. ^[1]

In the future, the conveyor will develop in large scale, expand the scope of use, automatic material sorting, reduce energy consumption and reduce pollution.

Continue to large-scale development. Large scale includes several aspects such as large conveying capacity, large single machine length and large conveying inclination. The length of the hydraulic conveying device has reached more than 440 kilometers. The length of the single belt conveyor is nearly 15 kilometers, and there have been several "belt conveyors" that connect the two places. Many countries are exploring more perfect conveyor structures for long-distance, large-volume continuous conveying of materials.

Expand the use of conveyors. Develop conveyors that can work in high-temperature, low-temperature conditions, corrosive, radioactive, and flammable materials, and can transport hot, explosive, agglomerate, and viscous materials.

Make the structure of the conveyor meet the requirements of the single machine for automatic control of the material handling system. For example, the trolley-type conveyor used by the post office to automatically sort packages should be able to meet the requirements of sorting operations.

Reducing energy consumption to save energy has become an important aspect of scientific research in the field of transportation technology. The energy consumed for transporting 1 kilometer of material for 1 kilometer has been taken as one of the important indicators for conveyor selection.

Reduce dust, noise and exhaust gas generated by various conveyors during operation.

Belt conveyors have the advantages of large conveying capacity, simple structure, convenient maintenance, and standardization of components. They are widely used in mining, metallurgy, coal and other industries. They are used to convey loose materials or pieces. It can also be composed of multiple units or with other conveying equipment to form a horizontal or inclined conveyor system to meet the needs of different layout types of operation lines. It is suitable for conveying powdery and granular materials with a bulk density of less than 1.67 / ton / cubic meter , Small, low-grinding materials and bagged materials, such as coal, crushed stone, sand, cement, fertilizer, grain, etc. The temperature of the material being sent is less than 60 ° C. Its captain and assembly mode can be determined according to user requirements. The drive can be an electric drum or a drive device with a drive frame. ^[2]
