The kilns of Norman, Kirtlington, Southam, Premier and Ellesmere Port all had a common design: they consisted of relatively short kilns (L/D inside brickwork of 9-19) without any sort of internal heat exchanger, from which the hot dusty exhaust gases were ducted through a rotary raw material drier. All except Norman had hard raw materials suitable for processing by dry grinding.
Condensate from the conditioning process is captured through a series of canals and trenches to an outside sump, where it is pumped back into the chamber for reuse. Process water can be reused for many cycles before needing to be replaced. The overall volume of process water in the log chamber during operation is approximately 10m3.
In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding. In order to enhance the drying ability, large ball mills are equipped with drying chambers.

Lepol preheaters are designed to be fed with nodulised damp feed, and can be applied to dry powder rawmix which has been agglomerated into nodules by addition of a small amount of water (Semi-Dry Process) or to slurry filter cake that has been formed into nodules (Semi-Wet Process).Semi-Dry Application
wet process cement kiln: the cement raw material is grinded with water powder into raw slurry (33-40% water) and then fed into the wet process rotary kiln and burn into cement clinker. dry process cement kiln: the cement raw materials are dried, ground, and calcined into the cement clinker in the dry process rotary kiln.
It improves the shortcomings of insufficient ash cleaning strength and uneven air inlet and outlet. By spraying compressed air, the dust attached to the filter medium is removed. It is very important to control the speed of the flue gas passing through the filter material (called the filter speed) during the operation of the pulse bag filter.
During the long-time operation of the bag filter, the dust particles will slowly gather on the surface of the filter bag to form a dust layer, which seriously reduces its working efficiency. If the filter bag is cleaned in time, the dust …
Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.
