Abstract: Loading ports in bulk, mainly metal ore is different from the coal loading system, the strength of the gate to demand higher problem, put forward the new type of jaw crusher gate instead of flat gate design, and on the strength of the two types of gate under different materials are compared, the jaw gates meet the port loading system according to different materials require high strength of gate design problem. Aiming at the strong adhesion of the powder ore, easy to adhere to the wall, the material dust can be changed by changing the funnel design, and the rectangular funnel is changed into a hyperbolic funnel .This paper improves the loading stability and loading efficiency of the rapid quantitative loading system of the port terminal, and provides the design idea for the research and development of heavy metal loading system.
