— The speed of mills depends upon their diameter; a ball-mill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times. Tube-mills run at a revolution or two faster (see Fig. 117). Some ores require much finer grinding than others to liberate the minerals, and this increases the milling cost.

Use a flow chart when you want to explain the steps in a process with someone else – such as someone that you're training for a job. They're useful in presentations and reports, too. Flowcharts are related to process charts. Process charts differ because they use a set of specific symbols to indicate the different steps in a process.

— Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
