Ball Mill And Sag Mill

26-11-2019· The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to

12-10-2017· Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.

Both the ball mill and the sag mill can process non-metals, ferrous metals, non-ferrous metals, rare metals, etc., and are divided into dry and wet types to meet the needs of various materials. The structure of the ball mill and sag mill is similar.

11-01-2018· Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

The working principle of the SAG mill and AG mill is basically the same as the ball mill machine, but the barrel diameter of the SAG mill and AG mill is larger. The raw ore enters the AG mill through the feeding inlet, and the material is brought to a high place under the rotation of the barrel and then falls.

13-02-2017· Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

15-06-2014· 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 Ø7.9m x 13.6m 2x8.5MW Ball Mill and a Ø11m x 5.4m 2x8.5MW SAG Mill , being the largest in China.

21-12-2016· 2 parallel SAG Mills each feeding 2 parallel Ball Mills (4 total). Around 50,000 TPD total grinding circuit capacity.

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

24-02-2020· Due to the great technical knowledge and safety protocols of Metso Outotec in this type of work, Codelco Andina invited the company to participate in the change-out of two of its 7500 and 8500 HP SAG grinding ball mill motors in the interior of its underground operation.

Grinding and processing. WEG offers the most reliable and efficient solutions for milling plants for ferrous and non-ferrous products with their experience of mill drive systems. In the heart of a processing plant, the ball and SAG mills must be driven by solutions that adapt to the characteristics of the minerals in line with the whole process.

2013-5-6Another factor in good ball mill design is the relationship between Bond Wi on crushed ore vs SAG ground ore. The latter measurement is required because the ball mills in SAG plants grind SAG discharge material and the grinding test should mirror the plant flowsheet.

In comparison to conventional tumbling mills, i.e., rod-and ball mills, the grinding media in an AG mill derive from the feed ore itself (Gupta and Yan, 2016;Hahne et al., 2003).
