The mixing stacker is suitable for the pre-homogenization stacking operation in the raw material yard. The cart walks continuously according to the logic program to realize the herringbone large stacking. There are control travel switches and limit travel switches at the start and end points of the stockpile in the material yard, so that the equipment that continuously travels at both ends of the stockpile can change the direction of travel according to the time-delay method of changing the starting point and fixing the end point, so as to achieve the purpose of reciprocating material. . It is one of the main equipments in the raw material pre-homogenization yard. It forms a complete raw material mixing and conveying system together with the mixing and reclaiming machine, the ground belt conveyor, and the batching system. Customized tailor-made, using three-dimensional design, the equipment capacity can reach up to 10000t/h, and the maximum turning radius can reach 60m
