【Ball mill working principle】 High energy ball milling is a type of powder grinding mill used to grind ores and other materials to 25 mesh or extremely fine powders mainly used in the mineral processing industry both in open or closed circuits Ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size usually the manganese iron steel balls or ceramic are used
Nov 01 1989 · Within the mineral processing industry a range of grinding conditions exists which include semiautogenous grinding SAG rod milling and conventional ball milling Each of these mill environments presents a unique environment for grinding media requiring the application of specific physical and chemical properties for optimum grinding media performance
d Feed Composition – The feed to the ball mill may contain one or several other constituents besides the ore itself The most common of these is water which displays a variety of effects on the grinding process depending on the nature of the material and the percent solids of the mix
Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced
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
a mill grindout no ore feed of 10 to 20 minutes is also performed before mill inspection or relining The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill This is usually performed soon after
For example your ball mill is in closed circuit with a set of cyclones The grinding mill receives crushed ore feed The pulp densities around your cyclone are sampled and known over an 8hour shift allowing to calculate corresponding to circulating load ratios and circulating load tonnage
