Research on design and calculation method of transfer chute of belt conveyor

Considering problems existing in the design of transfer chutes of belt conveyors,the evolution of calculation methods in the design of transfer chutes was reviewed,the continuous model method,DEM,model experiment and other methods were analyzed and evaluated,and selection methods of belt speed,roller diameter,material size and density in model design when adopting model experiment method were proposed forward.Key problems of unloading trajectory were analyzed,and different trajectory prediction methods were compared.Detailed process of deflector,material falling and material moving into the bottom curve chute in continuous model method was given,and the expression of material velocity in the chute was derived.Possible methods in basic steps of transfer chute design were analyzed,which provides a reference for transfer chute design.
