Optimization of Cement Grinding Operation in Ball Mills. Optimization addresses the grinding process, maintenance and product quality.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
Ensure that the lime shut-off valve to the ball mill is open. Start ball mill lime timer. The lime control valve should be pulsing open for 3 seconds every 30 seconds (after calibration of all lime timers). Open sodium cyanide shut off valve until fully open. Normal Ball Mill and Grinding Circuit Operation.
The procedures of the wet process are basically the same with the dry process, which can be divided into three stages: raw materials preparation, clinker calcination, and the cement grinding. All of these stages are covered in the article What You Need to Know about Portland Cement Manufacturing Process we mentioned before.
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
The analyses and KPIs included in the scope of the study vary from site to site but generally cover raw materials processing, raw mill, calciner, kiln, cooler, and cement mill (Figure 4). It is also recommended that certain preliminary data is provided before the onsite study begins, such as process flowsheet; heat and mass balance (where ...
Optimization of cement grinding using standard bond grinding calculations based on population balance models is successfully applied [4, 38]. Various grinding laws, energy relationships, control factors and controller design for cement grinding are discussed in [37]. Figure-1. Vertical roller mill for cement grinding [13].
7. Hurling of mill parts – From the mill platform high risk built up. 8.

The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball mills.The simple and compact vertical mill layout is cost competitive to build and offers many options for layout, …

Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration
Due to ever increasing fuel costs the target was to change the plants operation from import coal with 25 % volatiles to local lignite coal with up to 40 % volatile matters and a moisture content of up to 20 %. For this reason the coal mill had to be modified form cooler middle air to pre-heater exhaust gas operation.
