Why do ball mills have such high circulating loadsthe ball mill grinds the cyclones separate but the pump neither grinds nor separates so what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuita recent grinding bulletin addresses this question f

Oleg d neikov in handbook of nonferrous metal powders 2009 tumbling ball mills tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale grinding elements in ball mills travel at different velocities therefore collision force direction and kinetic energy between two or more elements vary
Dec 12 2016 ball mill power calculation example a wet grinding ball mill in closed circuit is to be fed 100 tph of a material with a work index of 15 and a size distribution of 80 passing inch 6350
Ball mill operation is often regarded as something of a mystery for several reasons ball milling is not an art its just physics the first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables
Apr 01 2013 it can be observed that for a ball mill circuit closed with cyclones circuit relative capacity is not expected to increase significantly by increasing circulating load from 250 to 600 this is because of the reduction in classification efficiency from 50 to 30 as calculated by eq
Analysis is continuing to further validate and improve the modelclosed ball mill circuits incorporating screens have lower circulating loads higher classification efficiency and can achieve higher capacity than circuits using single stage cyclones which have higher circulating loads
For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie
Shortly after the first applications of closed circuit ball mill grinding it was realised that classification increases mill capacity therefore over the years closed ball mill cyclone circuits
Ball mill is a type of grinder machine which uses steel ball as grinding medium can crush and grind the materials to 35 mesh or finer adopted in open or close circuit the feed materials can be dry or wet they are broken by the force of impact and attrition that created by the different sized balls
Oct 10 2016 the ball mill is a hollow drum closed with loading and unloading end caps filled with grinding media and rotated around its axisthe drum of the ball mill pic 1 is a hollow cylinder of steel lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material

The closedcircuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plant there are many factors that may affect the ball mills working efficiency and product quality during the operation in this article we will discuss the measures that can improve the ball mills performance
The larger the diameter is the slower the rotation will be ball mills are generally used to grind material " and finer down to the particle size of 20 75 microns to achieve reasonable efficiency the ball mills are to be operated in a closed system with oversize particles continuously being recirculated back to the mill and to be reduced
Conclusion the circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and hpgr circuits this is a wellknown fact for ball mill circuits that has been recognised for almost 100 years for hpgr circuits the knowledge is more recent and is still being investigated
Ball mills scale up well and in fact improve in performed with increasing size ball mills are available in sizes from laboratory scale also called milling jars of 01 usg to large 5000 gallon mills ball mills are available in various contact materials to accommodate contamination and wear requirements
