South mine in north-central British Columbia, which produces 300,000 ounces per year of gold, and the adjacent Kemess North deposit, which contains an indicated resource of 5.4 million ounces of gold and 2 billion pounds of copper.

Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical ...The foundations for the Ball and SAG mills were prepared with concrete and grout works, as well as anchor bolt and sole plate installation. The Ball and SAG mill shells were recently delivered, and are now being assembled and prepared for installation. The Company expects delivery of remaining mill components such as the motors in the near term.

VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.ball mill circuits operating within the normal range of appli-cation. This guideline does not directly address analysis of crushing plants and fine grinding circuits, but it is a useful reference for such endeavors. Applying power-based analysis techniques requires suf-ficient input information to allow actual specific energy

Both ball mills have been lifted into position and installation of the girth gears currently is underway. The mill installation is expected to be complete by the end of the year.Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

Lundberg, who has enriched my knowledge through his supervision, stimulating discussions and fruitful guidance. You always believed in me, gave me motivation, and showed a positive attitude towards my studies. My sincerest gratitude is extended to Professor Uday Kumar, Head of the Operation andFirst 50 TPD ball mill has been delivered to the site, with the second 50 TPD ball mill expected by October 31, 2014.
