The secondary source (40% of total emissions) is the burning of coal/fuel to provide the heat required for the calcination and clinkering process. One of the important parts of the cement production plant is the rotary kiln. Cement plant laboratories check each step in the manufacture of portland cement by frequent chemical and physical tests. A hydraulic cement made by finely powderising the clinker produced by calcining to incipient fusion a mixture of argillaceous and calcareous materials. It is usually composed of limestone, clay, slate, blast furnace slag, iron ore, etc (different admixtures gives cement different properties). This resource contains listings of over 2566 facilities worldwide (excluding China), and is the most up-to-date listing of cement plant information available. 14. Is the cost of cement production line high? These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions.This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C. In its simplest form, the rotary kiln is a tube up to 200 metres long and perhaps 6 metres in diameter, with a long flame at one end. 3.Overveiw of Cement Manufacturing process.
