Effect of ball and feed particle size distribution on the milling
1/6/2018· Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10
The Importance of Primary Crushing in Mill Feed Size Optimization
Typical head grades vary from 0.2 to 0.5% copper with an ore:waste ratio of 1. With currently outlined ore reserves, As stated, the mill feed size distribution data are summarised into three fractions: the fine fraction is interpreted as minus mill discharge grate size material, the medium fraction as critical size and the coarse fines, minimising the % medium while

AMIT 135: Lesson 5 Crushing Mining Mill Operator Training
The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm

Classification System Efficiency (CSE) is the percentage of “coarse” size (typically with reference to the P 80) material occupying the mill and can be calculated by taking the average of the percentage of coarse material in the mill feed and mill discharge. As this also represents the percentage of the mill energy expended on targeted, coarse size material, it is directly
Rod Mill an overview ScienceDirect Topics
Mill feed particle size is significant for AG/SAG load management. Monitoring of the feed to the mill by image analysis, for example, provides a measure of the particle size distribution (Chapter 4). Felsher et al. (2015) describe stabilization of SAG power draw by adjusting apron feeder ratios to target higher fines fraction in the SAG feed.
