Mathematical separator performance evaluation

Separators in the cement industry have the task of separating coarse from fine material, and it is worthwhile to fully understand the function of separators in raw and cement mills. Consequent troubleshooting, the elimination of technical barriers and optimum ­processing will result in an increase in the final product of the mill.

1 Introduction

The Teheran cement company was founded in 1954. At first, the plant production was started with a kiln capacity of 300 t/d clinker. Nowadays, the factory complex has eight cement production lines with a clinker output of around 12 100 t/d. Two smaller lines are already shut down, while a 9th line is under construction. The production at the complex consists of Portland cement types 1, 2, 3 and 5, oil well cement classes A, B, D, E and G, Portland pozzolan cement (types 1 and 2) and masonry cement (225).

For the stable operation of a cement mill it is essential to know its...
