Product Description Autogenous Mill for Grinding Ores, Sand Making, Stones Product DescriptionThis autogenous mill is typically designed to grind ores and other particulate matter in various fields like building material field, chemical industry, metallurgy industry, refractory material sector, and so on. Besides, it can also be used to grind materials with little iron content.As its nam ZTIC can produce below 12m autogenous mills (AG Mill) and semiautogenous mills(SAG Mill).autogenous / semiautogenous mills(AG Mill &SAG Mill) are utilized to grind run-of-mine rock or primary crusher discharge.especially medium hard and below valuable minerals and rocks with uniformly embedded coarse grains.AG Mills&SAG Mill AG Mills&SAG Mills:φ2.4x1.2~φ13x4.0m,Effective volume 5.6~216m3;Since ZTIC has been designing and manufacturing both semi-autogenous (SAG) and autogenous (AG) grinding mills under the ZTIC brand.ZTIC manufacture a full range of Grinding Mills for the Mining Sector. Our largest mills has been delivered to SINO Site to date are ?12.2m x 11m 28MW Gearless Drive AG Mills and ?7.9m x 13.6m 2x8 MW Twin Pinion Drive Ball Mills. These mills are scheduled of start up on 2012.Our market share in China exceeds 80% with the largest mills supplied to date being a ?7.9m x 13.6m 2x8.5MW Ball Mill and a ?11m x 5.4m 2x8.5MW SAG Mill , being the largest in China.ZTIC SAG/AG mills range in size below 12m diameter . They feature hydrostatic lubrication and can accommodate either a geared or gearless drive arrangement and are typically grate discharge and use metal liners.Semi-Autogenous (SAG) MillsDescription of Autogenous Mill(AG Mill): e suggests, it fan finish impacting and grinding materials totally by itself. So it is quite easy to operate. Moreover, it is easy and convenient to maintain, and is highly efficient.Semi-autogenous grinding uses a minimal ball charge in the range of 6-15%, and is primarily been used in the gold, copper and platinum industries but also in the lead, zinc, silver, and nickel industries.Autogenous (AG) MillsAutogenous grinding involves no grinding media as the ore itself is the grinding media.AG & SAG Mills2006 - ?8.0m x 2.8m AG mill.2007 - ?12.2m x 11m AG Mills (6 off in production)2008 - ?8.8m x 4.8m AG mill2008 - ?4.5m x 8.4m Scrubber2008 - ?10.37m x 5.19m SAG Mill (1 off in production) 2008 - ?8.8m x 4.8 m SAG Mill (project on hold) 2008 - ?9.15m x 5.5m SAG Mill (1 off in production)2008 - ?7.5m x 2.8m SAG Mill (7 off in production) 2008 - ?7m x 4.1m SAG Mill (1 off in production) 2008 - ?6.1m x 6.4m SAG Mill (1 off in production)Autogenous mills(AG Mill)/ semiautogenous mills(SAG Mill)The ZTIC autogenous / semiautogenous mills are utilized to grind run-of-mine rock or primary crusher discharge.AG/SAG milling can be accomplished with a variety of flowsheets. The optimum flowsheet should be established during the testing of the ore.Flowsheets include:AG-Single StageAG in a closed circuit with a crusherAG with a crusher + ball millSAG-Single StageSAG with ball/VERTIMILLTMThe shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking; there special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liner can be used;There are slow speed drive for medium and large mill;The high and low pressure lubricating station is equipped for medium and large mill;The control and protection system is controlled by PLC.Description of Semi Autogenous Mill(SAG Mill): This semi-autogenous mill, also called semi-autogenous grinding mill or SAG mill, is mainly used to grind ores and other particulate matter in different fields, like chemical industry, mining field, metallurgy industry, building material sector, and so on.It is an autogenous mill in nature, but it employs grinding balls to assist in its grinding just like in a ball mill. And it is mainly used in the first stage of grinding. When compared with a ball mill, it is characterized by its larger diameter and shorter length. The inside of it is lined with lifting plates to lift the materials inside up and around the inside of the mill, where it then falls off the plates into the rest of the ores. And it is widely used to process gold, copper, lead, zinc, alumina, nickel, platinum, etc. AG (Autogenous) / SAG (Semi-autogenous) Grinding MillsAutogenous (AG) and Semi-Autogenous (SAG) grinding mills have seen increased application in large mineral processing operations in recent years. They are rotating/tumbling mills in which comminution (size reduction) takes place without grinding aids. Consisting of a large diameter cylinder relative to their length (typically 2 or 2.5 to 1) these mills use large lumps of ore as the grinding media. Autogenous mills use ore exclusively as their grinding media but if hardness and abrasiveness of the ore does not lend itself well to full AG milling then a small charge of steel balls (6 to 15%) is added to assist in size reduction. This is known as a Semi-Autogenous (SAG) mill. AG/SAG mills bring about size reduction by a combination of impact, attrition and abrasion forces. Ore is swept up one side of the mill and at a certain point it falls back to impact the toe of the charge (bottom of mill). Ore particles in the body of the charge slide when moving to different heights and are subjected to attrition and abrasion forces. The inside liner of AG/SAG mills consists of steel or rubber liners and are fitted with lifter bars.AG/SAG mills can accomplish the same size reduction work that normally takes multiple stages of crushing, screening and grinding methods which accounts for its popularity. Often the product can be finished size or ready for final grinding in a ball mill or pebble mill. They can grind run-of-mine rock or primary crusher products with their feed size limited to what can practically be conveyed. In addition they can be less costly to operate with the reduction or elimation of expensive balls or rods.Product ParametersParameters of Semi Autogenous Mill(SAG Mill):Cylinder diameter (mm)Cylinder length (mm)Effective volume of cylinder (m3)Max. ball loading capacity (t)Rotate speed (r/min)Power of main motor (kw)40001600-360019-4213-2916.2310-71045001800-410027-6119-4315.3470-11050002000-450038-8327-5814.5700-150055002200-500051-11236-7813.8960-220061002400-550069-15248-10613.11400-310067002700-600093-20165-14012.52000-430073002900-6600120-26484-184122600-590080003200-7200160-347112-24211.43600-810086003400-7700197-429137-299114600-1000092003700-8300246-530172-37010.75900-1300098003900-8800296-640206-44610.37300-16000104004200-9400359-770250-537109100-20000110004400-9900422-909294-6349.811000-25000116004600-10400492-1064343-7429.513000-30000122004900-11000580-1246405-8699.216000-36000 Note: Parameters in the form is only for reference, and specific ones should be referred to the signed contract technology requirements.Parameters of Autogenous Mill(AG Mill):Cylinder diameter (mm)Cylinder length (mm)Effective area of cylinder (m3)Rotating speed at work (r/min)Power of main motor (kw)40001600-360019-4216.2240-54045001800-410027-6115.3360-83050002000-450038-8314.5530-120055002200-500051-11213.8740-170061002400-550069-15213.11050-240067002700-600093-20112.51500-330073002900-6600120-264122000-450080003200-7200160-34711.42800-620086003400-7700197-429113500-790092003700-8300246-53010.74500-1000098003900-8800296-64010.35600-12500104004200-9400359-770107000-15400110004400-9900422-9099.88400-19000116004600-10400492-10649.510000-22000122004900-11000580-12469.212000-27000Note: Parameters in the form is only for reference, and actual parameters should refer to the singed contract technology.Company Profile ZTIC AG Mills&SAG Mill FeatureThe cylindrical mill adopts the driving type edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor +reducer +pinion and gear as well as synchronous motor +air l\clutch + pinion and gear.Generally supported by static-dynamic pressure bearing on both ends.
