WhatsApp: +86 18838072829The use of pulverised coal for firing industrial furnaces was pioneered in the cement industry, and the perfection of the technique was a critical factor in the development of the rotary kiln in the 1890s. The desired requirement was for a system that could make cheap coal into a direct replacement for the more expensive fuel oil previously used.
WhatsApp: +86 18838072829The term coal refers to a range of solid materials originating from vegetation There is a considerable variation in properties, arising both from differences in the source materials, and in their subsequent treatment. In general however, for a coal seam to exist certain conditions must have been satisfied.

WhatsApp: +86 18838072829Cyclone 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.
