At present, the productivity in many industries has risen dramatically, with the developing of technology. The use of large and efficiency machinery, in one way or another, taking a major reform. For the underground coal mining industry, it is mainly made use of the excavating machinery, coal cutter, conveyor machinery, etc. However, the level of exploitation, technology, as well as conveying equipment, have a direct impact on the production process. In the process of coal mining, the coal capacity is high but the transfer efficiency is low. In other words, due to the low transport efficiency, the mining speed should be slowed down, which directly affects the capacity. In order to solve this problem, portable belt conveyor was designed and applied rapidly in various industries.
The Structure of Portable Belt Conveyor
The structure of portable belt conveyor includes the frame, an electric drum at the head frame, a tail drum at the tail of frame, as well as the connect belt between the electric drum and tail drum, the universal wheel, and the dam-board. The frame comprises an intermediate frame, a tail frame, and a head frame. Compared with the existing technology, the portable belt conveyor adopts a light frame and is provided with an electric roller, and the lower part of the portable belt conveyor is equipped with a universal wheel which can be moved optional, so that the portable belt conveyor can be adapted to the industry which is frequently changed and disassembled. The function of the head frame is fixed the electric drum, while the electric drum provides the power of the portable belt conveyor, and the tail drum is driven by the belt. Due to the handling location is changing continuously during the mining process, portable belt conveyor can be used, which conveying convenient, the connecting frame is light, the time of connection is short, and the production can be resumed in a relatively short period of time. The portable belt conveyor is convenient to move, when it needs to be adjusted, both the head frame and the tail frame are equipped with a tensioning device, which can move quickly from the front to the right through the universal wheel, adjust the angle of the mobile belt conveyor, and adapt to the needs of production and facilitate the operation.

Portable belt conveyor can replace the traditional SGW-40 conveyor. The structure of portable belt conveyor is reasonable, convenient for installation and operation, Flexible operation, strong adaptability, suitable for the industry where the handling location changes frequently. When the excavating machinery changes position, the portable belt conveyor can adjust the position at any time. In addition, the connecting frame of the portable belt conveyor can be prolonged, which can shorten the working time, improve the driving speed, reduce the labor intensity, extremely improve the efficiency of material transfer, and reduce the frequency of electromechanical accidents.

In summary, portable belt conveyor is widely used in the position where the handling location change frequently, and is used for short distance transportation and loading and unloading of bulk materials or conveying of less than 300 kg per unit weight. In short, it has a wide range of application, such as, ports, warehouses, construction sites, gravel yards, farms, etc. The bottom of the conveyor is equipped with a universal wheel, which can be moved freely according to the stacking position of materials. The commonly used portable belt conveyor has a width of 500mm, 600mm, 800mm and so on, and the length usually used is 6 meters, 8 meters, 10 meters, 12 meters, 15 meters, 16 meters, 18 meters, etc., which can also be customized according to the actual needs of customers.
