the operation of a classifier is to utilize Tromp diagrams. The Tromp curve involves calculating the selectivity efficiency based on knowing the particle size distribution of the classifier feed, the product fraction and the coarse reject fraction. The range of Tromp curves for separators with high and low efficiencies is shown in Figure 7.
This study aimed at optimizing both the energy efficiency and the quality of the end product by modifying the existing flowsheet of the cement grinding circuit. As a general application, mill filter stream is sent to the air classifier owing to its coarser size distribution than the desired product.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
cement quality. SEPARATORS : THE THREE GENERATIONS THE FIRST GENERATION THE SECOND GENERATION Examples: KHD (zub models) O & K Polysius Cyclopol Advantages: 1. With an external fan and small cyclones, most of the drawbacks of the first generation are solved. The external fan has a better efficiency and can be precisely controlled. 2.
Module 2 (Clinker production and material technology) will enable participants to obtain a deeper knowledge of the clinker production process and to better understand the impacts of the daily decisions of plant personnel on the plant’s performance (quality, electrical energy, fuel consumption and emissions).
We’ll provide an introduction to the Epsilon XRF equipment and the Mastersizer 3000 laser diffraction particle size analyzer including looking at classifier efficiency (Tromp curve) in the latter. Who should attend? All personnel interested in routes to cost benefits in the cement industry and needing an introduction to XRF and particle sizing.
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?

Cement Additives Division, Milan, Italy 2Mapei S.p.A. Microscopy Lab, Milan , Italy ABSTRACT Cement manufacturing involves a grinding process of clinker, gypsum and secondary mineral
The Tromp curve of an air classifier generally has a particular form. Accordingly, special parameters can be used for the evaluation of classification efficiency as well as the x 50 -median and the curve slope, e.g. τ – the minimum point of the curve and T(ξ) – the intersection of the curve and ordinate.
