Active Lime Production Line Lime Calcination Rotary Kiln Lime Kiln
Working Principle of Rotary Kiln
1. With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control up and down movement of the kiln body.
2. Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming.
3. The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured.

Process flow introduction: Qualified limestone is deposited in the storage bin, hoisted by the elevator and transported into the top bin of preheater. The top storage bin of the pre-heater is consisted of top and bottom level gages controlling the feeding. And then through the feed tube the limestone is distributed uniformly to all the inside chambers of the pre-heater.
The limestone in the pre-heater is heated to around 900 ° C by the kiln flue gas of 1150 ° C. At this time, about 30% of the limestone has been decomposition. Then the limestone is put into the rotary kiln by the hydraulic stem. In the rotary kiln the limestone sinters and decomposes into CaO and CO2. Then the decomposed limestone goes into the cooler and is cooled to about 100 ° C by the cold air and then is discharged. The 600 ° C hot air after heat exchange goes into the kiln and combusts with gas. The Exhaust gas blended with the cold wind go to the bag filter through the suction fan and then through the exhaust fan into the chimney.
The lime out of the cooler is transported into lime storehouse by vibration feeding machine, chain conveyor, bucket elevator, belt conveyor according to the customer’s request for whether making the screening other procedures.
