Abstract Based on the operation indexes of the final grinding system of 12 sets of raw roller press, it analyzed the problems in the current operation of the final grinding system of raw roller press, such as large particle size of limestone and auxiliary materials, easy wear of roller pins and roller surfaces, unevenness of circulating materials and new feeders, different quality of the parting valve, serious wear of the straight drum discharging port etc., The improvement and optimization schemes, such as adding linestone crushing system, adding sandstone ore crushing system, rationally arranging sealing feeder and bucket elevator, standardizing design and production of parting valve, adjusting the position of iron stripper and adding chute, adjusting the Angle of chute and adopting ladder chute are put forward. After the transformation, the raw material roller press system runs more stable, the feed into the roller is mixed evenly, the output of the roller press is stable at about 550 t/h, the power consumption is stable at about 10 kW·h/t, and each set of raw material roller press can save about 2 million yuan of electricity per year, so energy saving and consumption reduction has achieved.
