parameter on milling efficiency [2628]. For mill speed, impact load increases with mill rotation speed, but higher speeds result in the wearing of lifters and increased energy consumption. For mill filling, a minor filling level results in economic cost increases, and an excessive filling level result in mill does not break the particle.

Abstract. Analysis of the impact load causes is an important for operate of the rolling stand. The impact load can lead to wear of work rolls and the industrial accident. These bring about the increase of costs and deterioration of metal quality. This article is devoted to analysis of the impact load causes.

Increasing the circulating load to 500% brings that value up to times, for a further relative productivity increase of 30% (/ =)." By keep on increasing the circulating load, typically you reach a point where the mill is overfilled and milling efficiency decreases. thus, there is an optimum circulating load.

Impact energy depends on the specific mill design. It increases with mill speed, density and size of milling media (ball, rod, etc.). High impact energy is required to produce fine powders. However, very high mill speeds could lead to high wear of the balls inducing high contamination, excessive heating and lower powder yields.
