The paper briefly introduces the characteristics, principles, structure and function of the electric control system of belt conveyer.

This paper makes analyses of the causes of the belt conveyer s of f- tracking problem existing in the production of the supported belt conveyer o f the long- distance belt conveyer, through structural transformation of the be lt conveyer, its ability against the off- tracking is increased, obtaining exce llent results.

This paper briefly introduces the improvement of belt conveyer s fe ed ing runner for the purpose of prolonging the working life of the feeding runner and lightening the impact of the material transferred on the feeding runner.
