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. Typical examples are the various ores, minerals, limestone, etc.
Hydrocyclone (cyclone separator) is widely used in closed circuit grinding operations but it also has many other applications, such as desliming, degritting, and thickening.
If rods are used instead of steel balls, the mill is referred to as a 'rod mill'. Closed-Circuit or Open-Circuit. Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction.
