Stage 4: Finish Process Cement Production

Cement mill. A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

Cement grinding Vertical roller mills versus ball mills

The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over the last decade.

The cement mill - Understanding Cement

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum

Automation and Control in Cement Industries

Typical cement kilning systems are shown in Figure 3. 2.4. Cement Grinding The clinker with average diameter of some centimeters is ground, to reduce its particle size adding a small amount of gypsum (CaSO 4) to inhibit fast setting. Closed circuit ball mills are generally used to reach the given size distribution and specific surface area.

High-efficient cement manufacturing with POLYCOM®

More than 65 of the mills are producing high-grade cements in energy-efficient combi-grinding systems all around the world. The main characteristic of such a combi-grinding system is the pre-grinding of cement clinker in the POLYCOM®, which works in closed circuit with the static-dynamic separator SEPOL® PC, and after­wards finish grinding in a subsequent ball mill.
