fluctuation of delivered material is decreased. The entire process is called the blending operation in iron ore handling. Bed blending theory was firstly discussed by Gerstel in 1977 (Gerstel, 1977). Not far from that, Gy presented a new bed blending theory to suppress the continuous input variations for a steady output quality grade (Gy, 1981).
Ore blending generally refers to the blending of existing ore according to the production index before ore dressing. The purpose is to make the mixed ore properties more convenient for production, thus improving production efficiency and reducing production cost [1].
