Ⅱ. Principle of work and instruction feature
(Ⅰ) Principle of work: The rotary kiln is the main engine equipment for the cement production
The raw powder is entered kiln shell to calcined from the kiln rear high end. Because kiln body inclining and slowly rotation, causes the material to produce a kind of compound motion, which both along the circumference direction tumbling and along axial from high-end to low-end migration. The raw of inside the kiln through the decomposition & firing & cooling and so on process, after firing become the cement clinker, which should be dumped from the kiln shell low end, and enters the cooler.
The fuel is gushed in from kiln head, and carries on burning inside the kiln, sends out the heat quantity heats up the raw, causes the raw to be calcined and become the clinker, in hot air which forms with the material heat change process, enters the kiln rear system from the kiln feeding end, finally is dispersed into the atmosphere by the chimney.
(Ⅱ) Structure outline
The rotary kiln is mainly composed by the kiln shell, the transmission device, the supporting unit, the thrush unit, the kiln-head packing unit, the kiln-rear packing unit, the kiln-head cover and so on. Sees the rotary kiln diagram of mechanism.
