operating parameters. Mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study. It is hoped that the analysis of the data acquired will allow insight as to which parameters will require a functional form if they were to be integrated into a complete liberation model. · 1.2 ...
plant ball mill's grinding efficiency (Fig. 1). The functional performance parameters "mill grinding rate through the size of interest," and "cumulative mill grinding rates" from both plant and small-scale tests are applied to this task. A plant media sizing methodology, and industrial case studies, are provided. Background
by conventional ball mills, this optimization strategy involves maximizing SAG mill fresh feed tonnage while respecting the ability and limitations of the downstream ball mill – classification circuit to produce the desired coarser final product size. Secondary Grinding: Ball Mill ‐ Classification Circuit Optimization
into the mill as recirculating material; this prevents overgrinding of the finished product in the ball mill discharge. Heat generated during the grinding process can be dispersed by good mill ventilation and by injecting water. Layout of a ball mill / …

2.2. Grinding Test. In this paper, the wet ball milling process was used in the laboratory ball milling test. Before grinding, the ball mill was kept idle for 10 minutes and then washed together with the grinding media. Three types of ores were crushed and separated by a jaw crusher, and the ground par-ticle size of -2mm was selected.
My company using ball mill as the second stage of grinding usually experiences high mill mass. we are therefore forced to grind out in order to reduce the mill mass. We also experience excessive overflow of materials/feed entering the ball mill from the feed launder. What could be the causes of these problems we are experiencing.

Example Ball Mill GrindingExpert ™Solution The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage. An underloaded mill will break coarse ore well, but at the expense of added
For ball milling, you can assume a porosity of about 0.35 to 0.40 (the volume of space between the balls) and you can normally assume the pulp surface level is equal to the ball charge surface level. So do a crash-stop and measure the volumetric filling of the charge, then multiply that volume by 0.35 or 0.40.
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.
