With more than 100 years of experience in ball mill technology, Metso’s ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.
Power Consumption Of Ball Mill cz-eu. Scale-up of power consumption in agitated ball mills . Abstract. Previous investigations have shown that the specific energy input is the overall parameter of influence on product size during communition in agitated ball mills, from laboratory up to industrial scale.
The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem. This article summarizes 10 ways to improve efficiency, if you are worried about ...
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.
