Preventative Care of Rotary Kiln Refractory. The processing environment within a direct-fired rotary kiln can be harsh. The combination of constant rotation, extreme temperatures, heavy loads, and abrasive and corrosive environments, has the potential to cause significant damage or catastrophic failure to a kiln

Firing in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its as-received state. With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
