Improvement of Productivity Using Tromp Curve Measurement ...

In order to evaluate efficiency of the separation process, the Tromp curve of the separator is calculated and widely used throughout the cement industry. The Tromp curve shows percent of the material in each individual size fraction that is recovered into the coarse stream. The opposite of the Tromp curve

Tromp Curve - Example of Partition Curve

As may be seen from the table, a separation at S.G. 2.75 would result in a float product of 68.5% of the weight contain 3.8% of the tin of that size fraction. Laboratory separations in heavy liquids are “ideal” – all the sinks should report to the sinks and all the floats to the floats. In industrial applications heavy media is used (rather than the organic heavy liquids) and ...

Energy-Efficient Technologies in Cement Grinding

23.10.2015  2.6.4.4. Tromp curve of the TSV® separator. The performance of any classifier, in terms of size separation, is represented by an efficiency (TROMP) curve. An example for a classifier is shown in Figure 19. It describes the proportion of a given size of solids which reports to the coarse product. Mass-balanced particle-size distributions and tonnage flow rates around the separator were used to

Re: Separator performance - Page 2 of 3

This variant shows two possible solutions to calculate the Tromp curve. If the data are perfectly consistent, the two solutions are identical. Otherwise, the real Tromp curve should be in-between the two curves shown in the variant file. Depending on the precisions of the different data, the actual curve can probably be closer to one or the other curve shown.

If your focus is on "separator improvement", then it is all about the Tromp curve. Here is some sample data to illustrate my point: finish product. 3500 Blaines, (P32,P45,P63,P90,P212) = (78%, 90%, 97%, 99.3%, 100%) where P=1-R. feed. 2450 Blaines, (P32,P45,P63,P90,P212) = (53%,
