Nov 01, 1978 The ball mill is working in an open loop and the autogenous mill in a closed loop. The main part of the ground ore is fed to the ball mill (ca 55 t/h). Water is added to the feed flow as needed so that in the output of the mill the solid material concentration is ca 75'~'~0 (in weight).
The process plant is designed to treat 55 million tonnes per annum of copper ore from Sentinel mine, with a separate 4 million tonnes per annum circuit designed to process nickel ore feed from the Enterprise project or additional copper ore feed from Sentinel. Technical Report. Trident’s most recent NI 43-101 Technical Report.
Ball mills operations and maintenance seminar. Learn how to optimise your ball mill systems in this 5-day training seminar focused on best practices for operations and maintenance (preventive and reactive) to achieve energy savings, reduced maintenance costs and overall improved productivity of the ball mill systems.
The X41 shaft services the southern portion (X41 mine) of the copper operations, whilst the R62 shaft services the northern deep portion (Enterprise mine) of the copper operation. The decline is used for the movement of large equipment as well as for egress. A further two vertical shafts are used for hoisting of ore. These are U62 and M62 shafts.
The grinding mills convert the ore into approximately 230,000 tons annually of copper concentrate and 1,800 tons of molybdenum concentrate. The Client also awarded Fluor the follow-on work for the conceptual engineering and detail design for the extension to the 45,000 tpd copper concentrator building to house a new ball mill.
The ore larger than 10mm returns to the JP108 cone crusher for fine crushing. Ore less than 10mm directly enters the powder ore bin. 2.2 Grinding and flotation. The ore directly enters the GQC2700*3600 grate ball mill (grinding medium is φ100mm cast steel ball) from the powder ore mine, and then enters the single spiral classifier.
Ball mill for copper grinding processing. Grinding – Ball Mills. The ore would then flow into ball mills similar to the rod mills. Steel balls inside the ball mills were about the size and weight of a shot-put ball. These grinding mills rotated anywhere form 1 to 5 times per second. The end product of the milling process is ore ground to the ...

Jan 01, 2005 Ball-Mill Circuit Operation. Very often in SAG circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball-mill power is not used to the fullest extent.
The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble ...
