High-efficiency cement grinding - CemNet

This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.

Cement Manufacturing Process, Cement Bricks Factory ...

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.

MODELLING OF CEMENT GRINDING CIRCUITS FOR …

A first principles model of a cement grinding circuit is developed for the purpose of multi-variable model predictive control (MPC). The model is based on a series of mixed flow reactors with an ideal screen to model flow between the two chambers in the ball mill. The separator is modelled by efficiency curves.
