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 ...
Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern precalciner kiln system.
There are wet rotary kilns, rotary kilns with grid preheaters and rotary kiln with cyclone preheaters (with or without precalciners). Wet process kilns are generally older than dry kilns. Long wet and dry kilns have only one combustion zone, whereas kilns with a precalciner have a .

This blended raw material is called 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1,4001,500°C. In its simplest form, the rotary kiln is a tube approximately 200 m long and approximately 6 m in diameter, with a long flame (coal or natural gas) at one end.
