Online ChatImportant advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model in particular when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore .
Online ChatThe factors upon which the rate of flow of the pulp through a mill depends appear not to have received extensive investigation. In an article by Anselm translated by Pearson a method for the calculation of the time of passage of cement through a ball mill was given. The basis of the method is that the volume rate of throughput is known and it is assumed that the surface of the powder is .

Online ChatThe ultrafine slag slurry UFSS was obtained by the process of grinding the original slag in a wet ball mill which was mixed in concrete directly. The durations of grinding were 20ampx2009min 40ampx2009min and 60ampx2009min which were used to replace Portland cement with different percentages namely 20 35 and 50 and were designed to .
Online ChatThe Time that the ore spends in the grinding mill is called RETENTION TIME. This is a very important variable the longer the retention time the more the ore comes in contact with the rods the better and finer the grind becomes. To understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate. All the .
