Energy Consumption is very large in cement production. The grinding step in raw material, coal and clinker consumption accounts for about 70%~72% of the total cements production consumption power. So reducing grinding power consumption is the key to reduce the cement production power. The general ball mill has the limited in critical speed of rotation, so the cement grinding energy efficiency is very low.
Vertical roller mill is a new grinding mill, the material gravity involved in grinding when grinding the material, also avoids the phenomenon of material bottom sticking. Henan Zhenyuan Science & Technology Co., Ltd is specialized in manufacturing crusher, vertical shaft impact crusher and vertical roller mill. We did a lot of research and development to build a cement vertical milling machine a lot of theoretical research, study the relationship between the structural parameters of vertical milling machine for grinding and grinding with vertical impact energy amplification factor, be increased revolution speed revolution diameter improves vertical milling machine grinding rate conclusions.
According to the experimental results, the effect of grinding cement clinker factor is not only the thickness of the lining, but also grinding time, revolution speed, further comprising autobiography with the public around ratio. Our company added internal liner plate vertical roller mill in the vertical roller mill, the liner plate can protect the cylinder, enhanced internal mill stiffness, prolong grinding roller working life, also grinding body can automatic classification, to achieve different diameters to achieve different diameters corresponding to the diameter of the grinding material, to maximize the crushing grinding, grinding function.
