Low Power Consumption Vertical Shaft Kiln Active Lime Production Line
Process Flow of Lime Production Line:
1. Raw Material Conveying:
The 20-40mm limestone on the stock ground is sent to storage silo
by the B1000 belt conveyor with large inclination. In the storage
silo, qualified limestone with granularity more than 10mm will be
sent to the gravel silo, while limestone with particle size less
than 10mm will be conveyed to the powder silo.
2. Limestone Calcining:
The limestone calcining system is mainly made up of 10.5×8.5m
vertical preheater, 4.0×60m rotary kiln and vertical coolder whose
output is 600t/d and heat consumption of 5.75GJ/t. Limestone inside
the preheater is heated by high-temperature gases from rotary kiln
to 600-800°C, at which temperature limestone can be partly
decomposed. Then the limestone will be sent by 12 hydraulic push
rods to the kiln end, where it will undergo high-temperature
calcination before sent to the vertical cooler. The processed
limestone will be cooled down by cold air to 65°C. Air from the
vertical cooler enters into the rotary kiln as the second air to
take part in calcining process.
3. Finished Product Conveying:
The final lime will be sent to the storage bin for final products
by NE500 bucket elevator. After screening, qualified lime whose
particle size is more than 5mm will be sent to storage for active
lime, while powder lime whose size is less than 5mm will be sent to
storage bin for powder.
4. Gas Treating:
High-temperature gases from rotary kiln will do heat exchange with
limestone inside the preheater, and after that, the temperature of
these gases will reduce to lower 280°C. Then these gases will be
cooled down by multi-tube cooler to 200°C lower. Finally, they
enter into the bag filer before discharged into the atmosphere.
Mixed Burning Vertical Lime Kiln Process
The qualified raw materials and solid fuels are mixed uniformly
according to a certain proportion and then sent to the vertical
kiln through a single bucket elevator for calcination. After
calcination, the final lime products are discharged from the bottom
of the vertical kiln through a discharge device to the conveyor,
and the conveyor sends the final lime products to the storage silo.
The hot flue gas generated by calcination will firstly go into the
dust collecting system, and then the clean flue gas will be emitted
through chimney to the atmosphere.
