Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding. One of the most valuable aspects of blasting is the generation of very fine particles (, smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.
Ball Mill Size Calculations. Calculate and Select Ball Mill Ball Size for Optimum Grinding. In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.

SIZE REDUCTION AND SIZE SEPARATION
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
Size analysis by sieving To evaluate size distribution of tablet granulations Construction of various size frequency curves including arithmetic and logarithmic probability plots. IX. Size reduction: To verify the laws of size reduction using ball mill and determining Kicks, Rittingers, Bonds coefficients, power requirement and critical speed of Ball Mill.
Aim: The aim of the experiment was to achieve size reduction of the given granular material using a ball mill. REQUIREMENTS. Apparatus: Ball mill. Sieve set. Weighing balance. Sample. PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal

FM 306: SIZE REDUCTION AND SIEVING OBJECTIVE To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving. To estimate the energy required for the grinding operation. To analyze the results using the available theories. INTRODUCTION
Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls.
#0183;#32;In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media.
#0183;#32;A change in transfer size can be accommodated between and mm by an adjustment using the Bond ball mill work index. Starkey found that there was no observable difference in the energy consumption in a SAG mill or ball mill in this size range. This method of estimating mill power requirement has been successful in recent years.
