Zeki Ozek from Ozek Makina Rotary Kiln Services, Turkey, offers some insight into maintaining rotary kilns in a cement plant. A rotating kiln in a cement plant is the same as a beating heart in our body. That is why we all work hard to keep the kiln rotating. It is there to calcine every individual particle in thousands of tonnes of raw mix.

Rotary kilns [] are long cylindrical industrial furnaces that for their operation are slightly tilted as shown in Figure 1.They are used in a wide range of material processing industries. The material to be processed is fed into the upper end of the cylinder, leaving a considerable amount of freeboard or empty space.
Our lineup ranges from tableware firing furnaces to firing furnaces for cutting-edge energy devices such as lithium-ion batteries, solar cells and fuel cells. We offer our …

Unlike an unheated coating process, here, a rotary kiln heats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely. This process is commonly seen in the manufacture of roofing granules, where a mineral such as granite is coated with a colored pigment, producing a ...

Second, the kiln coating protection layer is tightly and firmly combined with the working end of MgO–FeAl 2 O 4 bricks even if the temperature in the rotary kiln is decreased to indoor temperature. By comparison, magnesia-chrome bricks usually incur breakage between the kiln coating and the working end, as well as between the reaction part ...
The difference between this Organic Combustion process and a non-heated coating process is that a Organic combustion is the thermal treatment of rotary kiln heats the coating material to just below its organic waste with the intent of reducing mass and liquefaction point.
