A 10 MW cement mill, output 270 tonnes per hour. 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.

The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity. Vertical roller mills can be transported in parts and constructed onsite, avoiding difficult logistical issues and associated costs. The fineness of product cement can be adjusted easily

The cement plants and process engineer (due to training and job title) is frequently asked to examine the “big picture” in a production/operations environment. This can be a formal request for a diagnostic review or a vague request from top management to see what’s wrong or what kind of improvements can be done with production/operations.

As we all know, in the whole process of cement manufacturing, the power consumption of traditional cement ball mill accounts for about two-thirds of the whole plant. According to statistics, the power consumption per ton of cement production is no less than 70 kW / h, but the effective utilization rate of this part of electric energy is very low.

Production rate could be bumped down to 800 to 1,200 tons per day for non-linear paving (e.g., paving of many radii/turnouts). Note that paving production rates typically do not include time for plant setup, commercial sourcing, and mix design approval. Also, paving generally cannot begin on the first day of construction due to setup of above.
