Description: Designed for autogenous or semiautogenous grinding, the 6 X 2 continuous feed Autogenous or SemiAutogenous Mill may be used as a pilot plant to determine the size for larger mills or for small scale milling projects. With the appropriate feed, the AG mill can reduce or eliminate the need for grinding media costs and eliminate iron contamination.
Grinding body such as silex lining brick, alumina lining brick, rubber lining,etc. are used in ball mill, pot mill and other fine grinding plants. Ball Mill Liner We can also supply different kinds of ceramic raw materials, such as wollastonite and high alumina cement, they are also popular wih our clients.
Autogenous grinding is gaining in popularity, as the grinding media costs are much less, and this process does not produce as much slime or fines as traditional rod and ball mills. Autogenous mills can handle both wet and dry operations. In some applications that require the grinding of minerals, such as talc, asbestos, and mica, dry semiautogenous milling is the preferred choice. Grinding is easily enabled in
Grinding Media Types To date, all IsaMill installations have taken advantage of the technologys ability to use a low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling).
The efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding. Sometimes, in order to improve the processing capacity of the autogenous mill, a small number of steel balls can be appropriately added, usually accounting for 23% of the effective volume of the autogenous mill (also known as semi
During the grinding process, the Smart Dentin Grinder is able to achieve consisten particulate sizing based on the sieves that sort the graft material. After the grinding and sorting cycles are complete, most of the collected material will result in particulate of 250 1,200 micron in size.
Ff the drill cores indicate that the ore could contain sufficient lumps in the sizes needed for ore media in autogenous and semiautogenous grinding, then bulk samples (750 kg) of mine run or primary crushed ore, with an even distribution by quantity in the size fractions between 100 mm and 200 mm, should be obtained for media competency tests. The AllisChalmers media competency test, which
The ball milling process prepared by rod mill, sag mill (autogenous / semi autogenous grinding mill), jaw crusher, cone crusher, and other single or multistage crushing and screening. Ball mill manufacturer With more than 35 years of experience in grinding balls mill technology, JXSC design and produce heavyduty scientific ball mill
Autogenous mills: It usually use harder ore to grind softer ores with harder ores instead of using ceramic grinding media. Semiautogenous mills: A SAG mill uses the same grinding way as an AG mill. But with the addition of grinding balls, it can grinding higher hardness ore and achieve the desired grind size faster. The improve of grinding efficiency means the cost of power and time can be saved. Stirred Mill:
Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. offers flexible autogenous (AG) mills, semiautogenous (SAG) mills, ball and pebble mills, as well as stirred mills to fit your needs.

Starting as small as 13 feet (4 m) in diameter on 330 HP and as large as 24'' ( m) in diameter on 3,300 HP, the 911MPE Semi amp; Fully Autogenous Mills tumble crushed ore without iron or steel grinding media. They are used when the crushed ore pieces are hard enough to perform all the grinding. SAG mills tumble mainly ore but they use up to 15% volume of steel balls to assist grinding. Semi
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. 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.
Ceramic beads made of zirconium oxide / magnesium stabilized. beads for lowest possible product contamination, for autogenous grinding / dispersion; Ceramic beads made of hard magnetic strontium ferrite (SHF) application as grinding beads in dry grinding process using an
Jan 01, 2016#0183;#32;Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills. Mills that grind hard ores with fracture characteristics

Autogenous grinding system ideal for contamination free processing. Multiple horizontally installed nozzles guides the pressurized air into the center and provide the energy for grinding products. The fine ground product is elevated by the grinding and classifying air up to the vertically installed rotor where the fine fraction are separated.
The primary mill liner task force was formed in 1977. Its function was to improve the operating costs and milling efficiencies of the ten x (27 ft x 18 ft) wet SAG mills that were operating at the time. The SAG mills are driven by two 3500 HP motors drawing a total of 5450 kW at 76% of critical speed. In March 1981, a liner metallurgy change was made. The original liners were made
Autogenous mills: It usually use harder ore to grind softer ores with harder ores instead of using ceramic grinding media. Semiautogenous mills: A SAG mill uses the same grinding way as an AG mill. But with the addition of grinding balls, it can grinding higher hardness ore and achieve the desired grind size faster.

The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding. In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of
Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in
