2 Ball milling – a ball mill with a diameter of 244 meters inside new liners grinding wet in open circuit When the grinding conditions differ from these specified conditions efficiency factors Rowland and Kjos 1978 have to be used in conjunction with equation 1

1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain size hardness density temperature and humidity the degree of

is the ball diameter d bmax is the maximum ball diameter in charge d bmin is the minimum ball diameter which can grind efficiently in a mill c is the exponent which characterizes the ball size distribution The condition for efficient grinding defined by Eq 7 will be fulfilled when the grain size distribution and the ball size

Ball Mills Mine Engineer 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

These ball mills are relatively small bearing mounted on a steel frame All ball mills are sold with motor gears steel liners and optional grinding media chargeload Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long offer features of operation and convertibility to meet your exact needs They may be used for pulverizing and either wet or dry grinding systems

Although it was developed nearly 50 years ago Bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills This paper discusses the basic development of the Bond method the determination of the efficiency correction factors based on mill dimensions and feed characteristics and the application of the results to designing grinding circuits

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution The following shows how the size or select the matching mill required to draw this power is

Ball Mills Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axis

With more than 100 years of experience in developing this technology Metso has designed manufactured and installed over 8000 ball and pebble mills all over the world for a wide range of applications Some of those applications are grate discharge peripheral discharge dry grinding special length to diameter ratio high temperature milling

Ball milling technique using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys In fact ball milling process is not new and dates back to more than 150 years It has been used in size comminutions of ore mineral dressing preparing talc powders and many

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight

Ball milling is one of the few unit operation that improves with increasing mill diameter If acceptable results can be obtained with a 12” jar mil then good result will certainly be obtained with a 72” diameter mill
