autogenous grinding mill process

Autogenous and Semi-Autogenous Mills

Autogenous and Semi-Autogenous Mills The optimum solution for wet grinding , intermediate size ready for final grinding in a ball mill, pebble mill, or , elimination of the process step with the use of AG/SAG milling is most advantageous Grinding circuit designGrinding is the second step of gold and mineral processing and the last stage of the comminution process The product from a crushing unit is fed to a grinding mill in order to decrease the particle size for subsequent processing.

Generation of low ash fine clean coal powder by autogenous ,Semi-Autogenous and Autogenous Grinding Mills (SAG Mills

Autogenous grinding mechanism is proposed in this paper to have a grinding where the grinding media is itself In this process, the harder fraction of coal is not grinded and this will enhance the breakage through grain boundaries due to bond strength [22,23]Autogenous mills have other advantages like, output of a unit volume for autogenous mills is lower, and the energy expenditure ,However, grinding in such mills becomes a complex process as the feed rate and mineralogical properties of the ore dictate the mill properti This makes the grinding process difficult to assess and control in autogenous and semi-autogenous mills.
