With the arrival of rotary kilns in Britain in 1900, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal". ...
Shaft kiln, also known as vertical kiln, vertical shaft kiln, is a vertical and fixed clinker firing equipment.The raw meal ball with coal is fed into cement kiln from the kiln crown, and raw meal ball moves from top to bottom, air move from bottom to top. In fact, the physical and chemical changes of shaft kiln are similar to that of cement rotary kiln.
The rotary kiln is the core equipment in a cement plant; its working condition directly affects the production efficiency and clinker quality of the cement plant.To keep the rotary kiln in great working condition, we must learn how to maintain it properly during daily production.

A. C. Davis, in Portland Cement: 1st Ed (Stone Trades Journal, 1904) on page 39 shows the Martin Earles picture, with the caption "First Rotary Cement Kiln to be successfully Operated in England".On page 41, an installation picture of the Shoreham kilns is shown, with the caption "Interior of Rotary Kiln Plant in England". The picture probably dates from 1901.
