The cement mill (or finish mill) presents a convincing case for automation as the optimization process employed by many cement manufacturers is mainly manual. Particle fineness of the cement is measured by way of Blaine measurements, routinely carried out separately offline. In a conventional setup, peak performance was ensured by manually ...

The working principle of vertical roller mills is relatively simple. In a rotating drum, grinding media (steel balls or ceramic beads) are fed through the mill's inlet, and the particles are ground into smaller sizes by the mechanical forces generated by the motion of the drum. The ground material is then passed through a classifier, which ...

Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

Here are six categories of cement production that have potential for optimization. Raw Materials. The first step in the cement process is the recovery of the limestone and sometimes the extraction of clay. Online elemental analyzers can monitor material chemistry in real time, allowing for adjustments that will help extend the life of the quarry.

Tertiary Air Flow Precalciner. In tertiary air flow precalciners, combustion takes place in air flow. In other words, it starts in gases with 21% oxygen and ends in about 1 to 3% oxygen. Raw meal from the preheater is fed into the precalciner at the level of a burner end and is conveyed to the bottom stage cyclone.
