These mills operate in conjunction with ball mills for iron ore grinding in Iran. Ball mill for grinding lime- stone for a flue gas desulphuri- sation system in a Korean power station.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.
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. Because of the range of mill sizes available, AG SAG milling can often be accomplished with fewer lines than in a conventional rod mill ball mill circuit. A diagram of types of AG SAG mills.Safe and efficient relining of smaller mills. Mechanical assistance is a critical requirement for safe relining and is often challenging in smaller SAG and ball mills. The Outotec Tube MRM provides fixed three-axis hydraulic crane support for relining tasks in mills that are unsuitable for traditional reline machines.

Home Blog How A Sag Mill Works How A Sag Mill Works. Sag Mill Troubleshooting Guide Autogenous and Semiautogenous mills liming AGSAG mills are often the optimum solution for wet grinding achieved in a slurry 50 to 80 percent solids AGSAG mills can accomplish the same size reduction work as two or stages of crushing and screening a rod mill and some or all of the work done by a ball mill.AG SAG and ball mill circuit data is also very poor. Use of equation 2 shows a very different picture, the results being illustrated in Figure 7. This shows that on average the “M” operating work indices of AG SAG and ball mill circuits are very similar and hence energy utilisation efficiencies are similar. Also the AG SAG and ball mill.
Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls.SAG milling extends itself to many applications due to the range of mill sizes available.
