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.
The FL ball mill is designed for grinding of clinker, gypsum and dry or moist additives to any type of cement. The mill may operate in either open or closed circuit and with or without a pre-grinder to achieve maximum overall grinding efficiency and high flexibility in terms of product quality. The mill has large through-flow areas,
where M (kg) is the mass of the grinding material feed to ball mill, and t (h) is the grinding time. Energy efficiency or energy utilization, η (m 2 /Wh), which is defined as the increment of specific surface area per unit of specific energy consumption, was calculated by:
Larger grinding media has a smaller grinding surface area, but offers a heavier weight that's generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization.
All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
