The use of circulating lubrication system ensures a long bearing life.Typical Separator Efficiency Curve (Tromp Curve) 90 The Tromp curve is a plot of the probability of a given size of particle in the separator feed that will be returned to the mill.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...

Relatively reasonable use of the Cement Grinding Machine can make the production of the whole machine play a higher use value, and the occurrence of the powder problem may have the following reasons. What is easy to occur is the problem of blockage of the main air duct of the new Cement Grinding Machine, which is the cause of most of the blockage.
The coincidence of the classification curves and the increase in by-pass with the feed rate are clear from the figure. Modelling cement grinding circuits 1475 With further studies at different plants the relationship between the model parameters and the design and operating conditions was obtained.
In order to obtain the greatest benefit from a high efficiency separator the operation parameters of the mill circuit should first be optimized. Tromp curves of the separator feed, fines, and tailings will show whether a high efficiency separator could provide any benefit. The entire mill circuit must be considered.
Separator performance. without Tromp curve what is the way to judge the separator performance by seive analysis of rejects,feed & fines. what is the normal range of residues on 212,90,63,45,32 mic for better efficiency of a separator in coarse,feed & fines & why?(for cement as well as raw meal) what is the optimum efficiency of a high efficiency separator?
