Cement Plants: Coal
This was a labourintensive process, and had limited takeup, but the arrival of the rotary kiln in the late 1890s provided a highly productive coalburning system, and the use of coal escalated rapidly. 50% of heat for drying and burning was provided by coal by 1913, and it was 90% in 1926.
Cement Plants: Oil
As has been mentioned elsewhere, the use of oil as a fuel played a critical role in the development of the rotary kiln. However, after the 1890s, even in the USA, the price per unit available energy of oil rose relative to that of coal, and in Britain oil was a "luxury" fuel during the first half of the 20th century.
