Low Mass

In recent years, with the continuous development of our society and economy, coal mining is also expanding the scale, and belt conveyor is widely used in coal mine production as a belt conveyor device. However, in practice, due to the low mass of reactive power, large loss of reactive circulation and large starting current, belt conveyor threaten the safety of coal production in addition to bring enterprises the economic losses. In this context, the realization of coal belt conveyor automation system design can not only reduce maintenance costs, extend working life, but also ensure life and property safety of mine workers, and ultimately improve the social and economic benefits of enterprises.
