in the AG/SAG mill product that can be considered as final circuit product, or Fines Fraction. The Fines Factor is the Fines Fraction expressed as a percentage of circuit feed (Q). T1' is the 80% passing size of the Fines Fraction. • Q2 is the fraction of material in the AG/SAG mill product that needs additional grinding in the ball mill,

Calculate and Select Ball Mill Ball Size for Optimum Grinding. Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work, this formula can be derived for ball diameter sizing and selection Dm lt;= 6 (log dk) * d^0.5 where D m = the diameter of the single sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines. The Vertimill energy savings range from 30% to greater

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...

Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition. Size: The smaller the media particles, the smaller the particle size of the final product.

The Effect of Ball Size Diameter on Milling Performance

6. PREDICTABLE SCALE UP – Scale up from small to large mills is very predictable. Ball milling is one of the few unit operations that actual improve in performance and efficiency with increasing size. The ABBE Slice Mill is the same as the product mill and can replicate all mill operating parameters but with very little product.

Dec 23, 2013· Particle size, number of balls, particle density, hardness, number of media used, time of grinding, and speed of the ball mill (rpm) are factors which will affect the process of milling. Size: The smaller the media particles, the smaller the particle size of the final product.

• Product size control is not critical and oversize material can be tolerated in the product Where size control of the final product is important, closed circuit grinding is the most efficient method of operation. The production of a higher quality product at a lower cost justifies the additional capital investment.

In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

Our ball mill grinding products apply the ancient principle of ball grinding to the industrial needs of the modern world. Many different industries can benefit from the grinding action that these mills offer: they are suitable for both dry and wet grinding as well as cryogenic grinding, and are commonly used for mixing or grinding chemicals, ores, paints and ceramic materials.

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. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Calculate Top Ball Size of Grinding Media -FRED C. BOND Equation & Method Previous Next 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.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
