the grinding production line process shown, the main device configuration in clinker, gypsum and mixed materials and other ingredients by a certain percentage after the conveyor belt, circulating elevator, belt conveyor, the separator device after removal of iron by the v-separator feed into the roller press small warehouse, warehouse with load sensing, under control and stability in the amount of material into the roller press, after the material from the roll after the hoist into the v
about 500 high-pressure grinding rolls hpgrs are in use in the cement industry for the pre-treatment of ball mill feed. this technology enhances the capacity of the downstream ball mill and reduces the total energy consumption of the grinding process by up to 50 %.
in the process of grinding system in the use of high-pressure roller mill can improve theproduction efficiency of the whole system from 20% to 30%. can make the total energy consumption of grinding system than the traditional grinding method reduces from 25 to 50%.
