Optimizing your SAG mill operation International Mining
21/03/2007 • Efficient operation even at higher mill speeds • Operatorfriendly smooth mill operation • Significantly improve wear life • Can be precisely designed to handle the given capacity • Can be easily retrofitted to existing mills The optimal performance of AG/SAG mills is the key to successful plant operationIf the SAG mill is not intended to be the ratelimiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to SAG Mill Process Control Grinding Classification The purpose of this paper is to outline the design, specification, and operation of the 85mdiam (28ftdiam) SAG mill commissioned at Kidston Gold Mines during January 1985 Amenability of Kidston ore to SAG milling, coupled with substantial cost advantages, led to the specification of this mill, equipped with variable speed drive to overcome the large variation in ore hardness SAG mill operations at Kidston Gold Mines Mining
SAG mills (semiautogenous grinding mills) Outotec
Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages Lower lifetime cost Simpler process requires lower capital and maintenance costs Versatile applications Wide range of mill sizes availableMill in Brazil and Lumwana having a 38ft, 18 MW SAG and one 26ft, 16 MW Ball Mill in Zambia, all three mills put in operation in 2008, as well as Los Bronces, Confluencia in Chile equipped with one 40ft SAG Mill of 22 MW and two 26ft Ball Mills of 164 MW commissioned in 2011 In the light of increasing interest in that technology various Sag Mill Operation ProcedureTo answer your question in general terms, yes you can use a SAG mill for a 2000 tpd operation, but it may not be the best answer In this case there may be a need to balance the grinding requirements for good tin recovery vs the requirements for good zinc recovery Will the ore be treated in a gravity or flotation circuit for tin recovery?SAG Mill for Small Operation Grinding Classification
