Introduction to Ball Mills. Ball Mills provide the most reliable method of fine grinding all solids down as far as lt 1 181. Depending on their size materials of construction and design Ball Mills are referred to by many names including Tumbling Mills Tubular Mills Ball Mills Pebble Mills and Jar Mills but no matter what the nomenclature they all operate on the same principle.
The Company carries business interruption insurance and will be assessing the applicability of the insurance and the relevant waiting periods in deciding whether to make a claim. There were no injuries or environmental damage.

VANCOUVER Nov. 22 2013 CNW - Copper Mountain Mining Corp. TSX CUM the quotCompanyquot or quotCopper Mountainquot announces that one of the two ABB transformers powering the motors on Ball Mill 2 at the Copper Mountain mine has failed and has caused Ball Mill 2 to be out of service for a temporary period while repairs are made. Mill throughput will be restricted by approximately 25 while the concentrator operates with just one Ball Mill. It is planned that the mill will be back to full production next week.
Spare coils are available and ABB have expedited crews to the mine to make the necessary repairs. As part of the original design plan for the concentrator the two Ball mills and the SAG mill have identical motors and transformers that are interchangeable in the event of a component failure. Because this failure involves just one transformer on Ball Mill 2 the concentrator is able to continue to operate with the SAG Mill and Ball Mill 1 at a reduced mill throughput. It is anticipated that production will be limited to approximately 1050 TPOH or about 25000 TPD until repairs are completed.
Jim O39Rourke President amp CEO of Copper Mountain commented quotThis transformer failure is a disappointing event for the operation at this time as our team has been making significant strides in improving tonnage through the SAG mill. Production of copper for the month of October was on schedule at 6.5 million pounds and although this event will slightly impact metal production all resources are being applied to minimize the impact. This outage is not expected to affect our ability to achieve our guidance of 65 to 70 million pounds of copper for 2013quot.

Joint venture JV partners Gold Road Resources and Gold Fields have experienced an interruption to production at the Gruyere gold mine in Western Australia.
The interruption was caused by a ball mill motor bearing failure upon the restart of the Gruyere processing facility following a scheduled maintenance shutdown.
Production was impacted for seven days to include this shutdown until processing operations resumed on Thursday September 24.
Gold Road now expects all-in sustaining costs AISC for its attributable share of production to peak in this quarter to 15401590.

Oct 10 2016nbsp018332The ball mill is a hollow drum closed with loading and unloading end caps filled with grinding media and rotated around its axis.The drum of the ball mill Pic. 1 is a hollow cylinder of steel lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
The rest of the paper is organized as follows. Section 2 introduces the working principle of the coal mill and its nonlinear dynamic model. Section 3 analyzes the mechanism of two typical coal mill faults and obtains a large number of fault data by simulation experiments. Section 4 introduces the working principle of the SAEs and makes certain improvements to the model. Section 5 is the simulation analysis that aims to verify the effectiveness of the proposed method in the fault diagnosis of the coal mill. Section 6 elaborates the conclusions of the study.
