Vertical roller mill for raw application p rocess materials
1. chaeng vertical mill comprehensive power consumption is 25kwht, saving more than 30 of power compared to the traditional ball mill system. 2. according to the market demand, it is convenient to adjust the cement varieties. 3. high cement quality to meet the construction requirements. 4.Raw material grinding process. however, tube mill, which has about 30 poor grinding performance as power consumption, has been still used many existing cement plant. the improvement of this tube mill grinding system is highly expected. descriptions the tube mill comminutes raw materials by impact and friction between grinding balls,Jun 01, 2012 the amount of carbon dioxide emission per kwh of energy consumption can be taken as 0.62 kg 22. the annual total farine production of the mill was 1,211,515 tons. the annual total energy consumption in the system is 29.98 10 6 kwh and the corresponding carbon dioxide emission is about 18,592 tons a year.Specific power consumption spc kwhtonne. ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. closed circuit ball mill with Consumption typical power requirement of finished ball mill example total consumption 3333 kw, 104 th product total power consumption 32,0 kwht mill power consumption 27,5 kwht 85,8 energy consideration in cement grindingThe cement vertical mill is a grinding equipment developed on the basis of similar grinding mills, so it has many irreplaceable advantages, such as high grinding efficiency, low power consumption 20-30 less power than ball mill, large drying capacity simultaneously dry and grind materials with moisture up to 10, large particle size of grinding materials, simple grinding process, small The power consumption of cement pulverizing system with small capacity of pre-pulverizing section is still in the low level of 38 kwht or even above 40 kwht. in a word, the more work done in the ball mill section, the higher the grinding power consumption of cement grinding unit.This gives good cement performance, and reduces energy consumption by 20-40 compared with a standard ball mill system. capacity of cement mills the cement mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant’s kilns.
