According to different operation process, ball grinding mill can be divided into continuous ball mill and batch ball mill. The feeding and discharging process of the continuous type ball mill is continuous, which can be produced in open or closed circuit grinding applications, such as cement ball mill, ceramic ball mill.With than 100 years of experience in ball mill technology, Metso Outotec 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.
Oct 30, 2019 Grinding in Ball Mills Modeling and Process Control. Keywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.Mill returns (tailings), z [tons] is the amount of material in the mill (also called the mill load), d represents the clinker hardness, α(v) is the separation function and ϕ(z,d)is the ball mill outflow rate. The grinding function ϕ(z,d)is shown in Fig.2 for different values of d. It is a non monotonic function of the mill load z.
