| In response to the problems of the HFCG160-140 roller press double closed circuit combined grinding system,such as uneven feeding of the V-type powder selector,fast material flow rate in the cement mill,low cement yield,insufficient powder selection efficiency of the high-efficiency powder selector,and accumulation of material in the V-type powder selector air duct,process optimization and equipment renovation have been implemented.By adjusting process parameters and improving equipment structure,the above problems have been effectively solved. After optimization and renovation,the electricity consumption of P.O42.5 cement decreased from 27.5kWh/t to 24.38kWh/t, and the unit time increased from 255t/h to 275t/h,significantly reducing production costs and improving production efficiency,creating good economic benefits for the company. |
