We believe everyone knows the ball mill and the large vertical mill specifications, but which one is better in the production? The following aspects analyze the difference between a vertical mill and a ball mill.
First, the difference between the vertical mill and the ball mill is analyzed from the aspects of structure and installation. The vertical grinding structure is simple, adopts vertical vertical installation, small floor space, simple foundation construction, convenient installation and short time. The structure of the ball mill is relatively complicated, and the horizontal horizontal installation is adopted, the installation technology is difficult, the foundation is required to be high, the cycle is long, and the floor space is large. Both can be arranged in the open air, but in general, the construction area of the vertical mill is 70% of the ball mill, the building space is 50%-60% of the ball mill, and the investment cost is low.
Secondly, the difference between the vertical mill and the ball mill is analyzed. The vertical mill mainly adopts the grinding and crushing method, and the impact force is second. It is suitable for fine grinding and ultra-fine grinding, the grinding media consumption is small, and the inner life of the inner lining is long. The ball mill mainly adopts the impact crushing method, followed by the grinding, which is suitable for rough grinding and fine grinding, the wear and tear consumption is large, and the inner life of the inner liner is short.
In addition, the process flow of the two is also different. The vertical mill integrates crushing, drying, grinding and grading and conveying. Compared with the ball mill, the vertical grinding process is simple, and the capital investment is small, which can save one dryer for the mill system. In addition, there is a separator in the vertical mill, which uses hot flue gas to transport materials. It does not need a powder separator and a hoist. The dust-containing gas is directly collected into the collector, so the vertical mill system has simple process, low failure rate and high operation rate. The layout is compact. In general, the finished product of the same fineness adopts the vertical grinding process. After two-stage grinding, the fineness of the product can meet the requirements. The traditional ball mill process requires three-stage grinding. After the above analysis, it can be seen that the vertical mill has advantages in terms of structure and installation, crushing method and process flow.
