efficency of ball mills

Ball mills 5 5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40% by volume ball charges This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor The paper will propose possible operating Ball Mill Ball mill is the key equipment for grinding after the crushing process which is widely used in the manufacture industries such as cement silicate new building material refractory material fertilizer ferrous metal nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials

How to improve the grinding efficiency of the ball mill

The ball mill's low grinding efficiency low processing capacity high production energy consumption and unstable product fineness are problems that most concentrators will encounter How to effectively improve the grinding efficiency of the ball mill is an important issue This article summarizes 10 ways to improve grinding efficiency

The ball mill has the advantages of simple structure stable performance and large crushing ratio (3~100) which can be used for wet or dry grinding This paper introduces some factors that affect the grinding efficiency of ball mill

Ball Mills are generally used to grind material 1/4 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

The mill used for this comparison is a 4 4-meter diameter by 13 6 meter long ball mill with a 5000 HP drive motor It is designed for approximately 90 s ton per hour This type two-compartment mill is a state- of-the-art shell supported cement finish mill The torque and time requirements of the mill with the ball

Ball Mills

For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice In the last decade vertical mills have taken an increasing share of the cement milling market not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely
