flow sheet? The length of a mill flow is determined by the linear inches or millimeters of roll length in the total process flow. Sifter and purifier capac-ity is sized to support the grinding capacity of the mill. The calculations for roll length, sifter surface, and purifier width are listed in Tables 1 and 2 (see Page 52).

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.
— 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. Ball Mill Product Classifying
Basic Mill Linings. Use rubber linings wherever possible due to lifetime, low weight, easy to install and noise dampening.; When application is getting tougher use steel-capped rubber, still easier to handle than steel.; When these both options are overruled (by temperature, feed size or chemicals) use steel.; Ore-bed is a lining with rubber covered permanent …

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
— The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills.
