Autogenous mill, ag mill, semi-autogenous mill, ball mill.In this case, xinhai efficient autogenous mill solved these problems effectively.Xinhai efficient autogenous mill can achieve two and three stage crushing, part or all crushing of ball mill and rod mill, it is suitable for the coarse grinding after coarse crushing.
Prediction of grinding media wear in sag mills minevik sag mill media wear.Autogenoussemiautogenous mills567.Agsag mills 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 of a ball mill.It is possible with automatic operation to save power.
Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media.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.
Generally for successful autogenous grinding, there needs to be a definite division between media and mill feed with a ratio established between media and feed as to difference in size and feed rate to the mill.The same basic principles of grinding media sizing to feed size as used for rod and ball milling should apply to autogenous grinding.
The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power.When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.Contact supplier.Professional design rod mill.
Grinding mill and grinding mill motor ratio.As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
Rod mills are very similar to ball mills, except they use long rods for grinding media the rods grind the ore by tumbling within the mill, similar to the grinding balls in a ball mill to prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 14 to 16 rod mills accept feed up to about 50 mm 2 in.
Sag is an acronym for semiautogenous grinding sag mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill.Chat now ag autogenous grinding youtube.Animation of the grinding action inside an ag autogenous grinding mill like cloths tumble in a drying machine, rocks , chat now.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill.Agsag mills 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 of a ball mill.
Autogenous mills operate mechanically like ball mills however the media used for grinding differs.Simply put in autogenous grinding the media is also the material that is being ground.Get price ag autogenous grindingyoutube click to view on bing0 51.Aug 06 2015 animation of the grinding action inside an ag autogenous grinding mill.
A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill.The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit.

Concavex grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker.The advantage of concavex medium is its ability to increase mill capacity because of its interlocking shape and increased density per cubic foot of grinding charge.
Different grinding media of ball mills, rod mills and sag mills.Crushing ratio comparison.The biggest feature of sag mills is the large crushing ratio, which can crush and grind the materials to 0.074mm at one time, accounting for more than 20 to 40 of the total product.
Every mining operation has a unique grinding process.Metso has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest sagag mills in the world.Our experts welcome the opportunity to assist you with circuit and circuit control design as well as start-up, operation, and optimization of your mill.
