Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge.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.

Aug 27, 2007 Grinding circuit must provide stable particle size distribution and should also operate in a way to maximize mill efficiency. Fuzzy logic based on-line optimization control integrated in an expert system was developed to control product particle size while enhancing mill efficiency in a ball mill grinding circuit. In the supervisory level, fuzzy logic control determined the optimum set-points.Since for the ball mill design we are using 80 passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as 𝐶𝐶3 = 2.44 0.2 (3) However, it is important to note that C3 =0.914 vessel used in producing the ball mill was got from a.

Ardakan Iran. In ball milling, particle size reduction occurs by impact and attrition breakage. It is established in ball milling, the particle size distribution curve of the product is generally parallel to the feed size (Bond, 1961). In HPGR, size reduction is attributed.Ball Size Distribution. As the mill starts, grinding action and throughput increases. However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Correction when the product size is less than 75 microns F †“4 = [P †“80 + 10.3 1.145P †“80].
