Study on the Determination Method of the Inclination of the Large Height Chute

For a chute with a large elevation difference, it is important to choose the right inclination of chute, both to ensure the material will accelerate at a steady flow in the chute, and to meet the requirements of flow speed. In this situation the chute inclination cannot be determined according to conventional methods for a single factor, because in order to ensure the safety and environmental protection of the chute transportation, the chute inclination’s relationship to the moisture content of materials, the content of rock powder and a variety of other factors are considered. Through a theoretical analysis and experimental study, the results showed that the maximum water absorption in the moisture content, the water content and the inclination of the chute are proportional. Rock powder content and the relationship between the inclination tended to a logarithmic function relation curve. Put forward a formula for determining the chute inclination.
