Cement is created by heating crushed limestone with clay, slate, blast furnace slag and other materials, then cooling and grinding the resultant clinker to create a fine powder. Most modern cement plants use a dry process which is more thermally efficient than the older wet process. The process consists of the following stages:

5. Cement grinding. At the cement mills the clinker is mixed with other additives required for producing the specific type of cement. Gypsum for OPC, limestone for limestone cement, and slag for slag cement. The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator which separates fine and coarse product ...

Going forward, I would make a few improvements to my design to make it easier to use and more practical. Use a wider and shorter pipe. Use PVC cement for a better seal and stronger hold. Find some actual lead balls to do the milling. Implement some sort of screen in the mouth to prevent the balls from falling out when emptying the mill.

The produced coarse recycled concrete aggregate is sent to a rotary kiln for calcination, which can burn the combustible impurities into ashes. The calcined aggregate is then ground into powder by ball mills and Raymond mills. The calcination treatment method removes the combustibles in the recycled concrete aggregate and reduces the moisture ...

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
