YUHONG 250-500TPD Rotary Kiln With CE ISO Approved
Description of Lime Production Line:
This active lime production line is a complete line that includes vertical preheater, rotary kiln, grate cooler, etc.
The processing flow of lime production line :
Qualified limestone stores in silos and be shipped through the preheater by the elevator into the silos which is on the top of the preheater. The preheater on the top of silos is consisted of top and bottom level meter controllers which control the feeding capacity.Then through the feed tube the limestone is distributed to the indoor compartment of the pre-heater.
The limestone in the preheater is heated to around 900 by the kiln flue gas of 1150 . At this time, about 30% of the limestone has been decomposition. Then the limestone is put into the rotary kiln by
the hydraulic rams. 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 bythe cold air and then
is discharged. The 600 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 limestone out of the cooler enters into the lime storehouse through the vibrating feeder.
Working Principle of Lime 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.
