Operation Guide for Vertical Roller Mill in Cement Plant,
Cement ball mill is a main cement grinding mill with a low energy utilization rate (only 3%-5%). Compared with the grinding energy consumption, most of its energy is consumed by collision heating and noise. Therefore, we usually adopt the cement roller press to replace the fine crushing and coarse grinding role of the ball mill.
Cement Mill - Cement Grinding Machine | AGICO Cement,
Cement grinding mill is usually used in the clinker grinding process. It is the final stage in cement production which will directly affect the cement product quality, output and benefits. Clinker particles, gypsum, and other materials in cement grinding machine will be ground together into fine powder to match the fineness of the finished product.
Cement grinding Vertical roller mills versus ball mills
For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
