Working Principle of Rotary Kiln
Rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal.
Introduction to Cement Production
With the development of social productive forces, the cement production technology gets continuous progress and gradually becomes mature and perfect. People summarize vividly the production process of cement as " Grind Twice and Grill Once ", that is, with a proportion of raw materials, first made by grinding raw material, clinker and then fired in the kiln, and finally made by grinding cement. In the process, the kiln is the core equipment, it is often represented by the kiln in the research of the history of the development of cement technology. Cement production has gone through the warehouse kiln, vertical kiln, dry rotary kiln, wet rotary kiln, dry process rotary kiln and other stages of development. And the final formation is the modern kiln dry process cement production, which takes Suspension preheater and Pre-decomposition as a core technology. The modern science and technology and the latest achievements in industrial production, for example: Computer-controlled network mining of raw materials extraction, materials pre-averaged, raw meal, extrusion mill, a new heat-resistant, fire-resistant, heat insulation materials, and IT technology, are widely used in dry cement production process, to make cement production of efficient, high-quality, energy conservation, cleaner production, and meet environmental requirements and large-scale, automation, scientific management features of the modern cement production methods.
