HBIS Group Co., Ltd Sijiaying Yanshan Iron Mine adopts a fine-crushed closed-circuit classification process with large-scale banana screen 2LKBB3673 and HPGR. The screening efficiency of banana screen is more than 85%; and the capacity is 1200-1600T/h which is 2-3 times of the original Model3673 linear screen. The costs of power consumption in crushing workshop, screening consumption, and spare parts consumption have been saved for a total amount of 705,300 CNY each year. Meanwhile, the maintenance task of the screen and the labor intensity of the workers on-site are greatly reduced.
