Put cement clinker into the cooling machine after it is ejected from the kiln head hood. A dry rotary kiln makes the raw material into raw powder, whose water content is less than one percent. The advantage is that it saves more energy than a wet rotary kiln. The disadvantage is that it may happen that the ingredient in mixed material is uneven.

20-09-2021How Cement Is Made in A Rotary Kiln. Originally, when the process was first developed, manufacturers used the "wet kiln" process. This involved pouring in a slurry of clay, limestone, and water. While the process was easy to set up, it required an absolutely enormous rotary kiln to be effective – at least 200 meters long.

The rotary cooler is one of the important equipment in the rotary kiln system. Its function is to cool the clinker from the rotary kiln (1000-1300℃) to below 200℃, while improving the quality and grindability of the clinker. Product Advantages: 1. Short cooling time and fast speed. 2. Wide range of application. 3, Simple operation, less
