SAG milling extends itself to many appliions due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these ...

The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S dBWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P information, along with the ore specific gravity, is used to calculate necessary mill sizes and motor power in industrial appliions.
the size of the ball mill . GM stone crusher machine is designed to achieve maximum productivity and high reduction ratio. From large primary jaw crusher and impact crusher to cone crusher and VSI series for secondary or tertiary stone crushing, GM can supply the right crusher as well as complete crushing plant to meet your material reduction requirements.
mills. The mills in mining operation grind the product from the crushers to fine material ready for treatment. Rod mills, ball mills, autogenous mills, and semiautogenous mills (SAG Mills) all have a number of lubriing and hydraulic systems, and they must work to keep mineral output high.
Ball top size diameter calculation The Cement Grinding Office. Db = the top size of the grinding media in mm. Pf = size in µ of the 80% passing in the fresh feed. C = 200 for ball mills and 300 for rod mills.
The results showed that the HPGRball mill circuit achieved a 21% reduction in energy consumption over the existing SAGball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGRstirred mill circuit showed a 34% reduction in .

Under low impact load, Manganese Steel Ball Mill Liner can achieve HB300~400, Under high impact load, can achieve HB500~800. Different impact load, the Manganese Steel Ball Mill Liner's surface hardening layer depth can be up to 10~20 mm. High hardness of hardening layer can .
Jun 30, 2007 · This signature could be effectively used to optimize the milling performance by investigating this signature's relation to mill product size, mill throughput, makeup ball size, mill speed, liner profile and ball addition rates. At the same time, it can also be used to design balls and liner systems that can survive longer in the mill.
Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens. Figure 2 Comparison of the OWi and SSE75 of the SAG and ball mill for 10 surveys conducted on the same circuit at different times.
The Pearlitic Chromium Molybdenum Alloy Steel Liners are widely used in AG Mill,SAG Mill and Ball Mills. Hardness: HB310375 (equivalent to HRC3342) Impact resistant Value: Ak≥60J (60×10×10mm) in normal ambient temperature. We can produce pearlitic CrMo steel as per AS2074 Gr. L / 2B. High Chrome White Iron Series
The original Barratt papers do not specify values to use for PC and PR but we can use the same values as Table 1 of 10 000 µm and 2100 µm respectively. The value T80 is the "synthetic" transfer size between the SAG mill and ball mill . Chat Online; Difference Between A Crusher And A Sag Mill
Jul 21, 2006 · Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 ...
The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 2075 mm. The biggest size is chosen when the mill is used as a primary grinding mill. For fine grinding
Nov 26, 2019 · The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
