Abstract: What is designed in this paper is slotted roller belt conveyor, the design requirements are: transport of materials: coal, transport capacity: 450 tons / hour, transmission length: 25 meters, 2 meters high upgrade; Bulk Density: 900 kg / m 3; materials in the dynamic accumulation of the surface with angle is 40, conveyor speed: 1.2 m / s, on the trough roller arrangement. Design of a tilt the overall state of the idler trough arrangement used; under the (return) the use of parallel idler rollers. When the materials are transport up through the conveyor, the tilt angle is 3.80 <150, so take the use of small-angle design. As the selection of the tailstock, we take the use of Tailstock screw tensioning device so that the conveyor system can always maintain the necessary tension. And Solidworks is used to do the finite element analysis on the connecting axis, to meet the required strength.
Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of belt conveyor.
