Although it was developed nearly 50 years ago, Bonds 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.

, mill ( bl mil ) ( mechanical engineering ) A grinding media charge calculation in cement ball mills CachedThis page is , Office The calculation of the thermical balance of the ball mill is now proposed according 2 ,calculations for design of , it is one of the most famous stone and mineral processing company in theIn order to design a ball

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, i.e.,

Mill Steel Charge Volume Calculation. We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

Conditions for stable operation of the grinding charge in a ball mill. In a ball mill the type of motion of the grinding charge depends on a number of factors but mainly on The stability of the grinding charge during the cascade opera Calculation of the tangential force and the normal pressure

determine mass balance of a ball mill grinding circuit. TECHNICAL NOTES 8 GRINDING R P King Mineral Tech. Figure 82 Media motion in the tumbling mill 81 Grinding, Where Mc is the total mass of the charge in the mill and Tf is the, steel balls in a ball mill, .

If it is a grate discharge you will have more flexibility of the total charge. Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry. The ball charge is determined by the operator targeting the balance between grind and throughput, the higher the ball charge the more aggressive the milling becomes.
