The earliest successful rotary kilns were developed in Pennsylvania around 1890, based on a design by Frederick Ransome, and were about 1.5 m in diameter and 15 m in length. Such a kiln made about 20 tonnes of clinker per day. The fuel, initially, was oil, which was readily available in Pennsylvania at the time.

Cement Kilns: Firing systems

"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.

Cement Kilns: Early rotary kilns

Rotary kilns used coal rather than the increasingly hard-to-get coke. Furthermore, because the coal was used in a ground state, the use of the smaller size-grades of coal was a positive advantage, and these, because of their bad handling characteristics in most other applications, were by far the cheapest.
