Abstract: Particle grinding is a final stage in the comminution process used to liberate minerals from gangue in mineral processing plants. Semiautogenous grinding (SAG) occurs in tumbling mills which use both large ore particles and steel balls for grinding. Grinding is the most energy intensive mineral processing unit operation and hence its optimisation is of considerable interest to industry.

The selection of a mill for autogenous or semiautogenous grinding is complicated by the fact that the hard and large particles in the ore itself form the grinding medium and in turn have to be reduced in size. The selection will therefore depend on 1. the intrinsic property of the ore and. 2.

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. Finally, in the actual production, Xinhai efficient autogenous mill improved production efficiency, controlled the cost in the operation, the customer is very ...

Feb 12, 2018· Semi autogenous grinding (SAG)technology, as an effective measure to reduce the capital investment and production cost, has been widely recognized. It has been widely applied in nonmetal mineral processing, ferrous metal mineral processing and nonferrous metal mineral processing, and is being popularized gradually in gold processing plant.

Oct 12, 2017· SAG is the abbreviated form for SemiAutogenous Grinding Mill. This type of Mill is used for grinding large fragments into small pieces. Pieces are then used for further processing. The SAG mills are generally used in preprocessing of any type of material in grinding process. SAG mills are also known as first stage grinders.

The grinding balls used in semiautogenous mills must be of top quality so that they will not break from the impact forces encountered in primary semiautogenous mills. Pilot plant testing for primary autogenous or semiautogenous grinding gives the following information needed for selection of mills, circuit design, and mill design.

The Autogenous/Semiautogenous Grinding Mills are in most cases used as primary crushers. AG Crushers use the ore exclusively as their grinding media. In case the hardness and the abrasiveness of the Ore is not suitable enough to carry out the grinding process, steel balls are added inorder to assist the process; these are called SAG Crusher.

1. Introduction. Semiautogenous grinding (SAG) mills are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their comparative advantages, such as higher processing capacity, lower physical space requirements, and lower investment and maintenance costs, as compared to conventional circuits.

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. AG/SAG 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.

Xinhai could supply the best semi autogenous mills with superior quality. Xinhai has production base over 100 hectares, which could ensure the semi autogenous mill production. Semi autogenous mill made by Xinhai are widely used in the mining plant and has received many praises for energysaving.

Question what is an Autogenous mill? An autogenous (AG) mill is a grinding mill used in the minerals processing industry. It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force. Gravity assist...
