50t/d Enverinomental Friendly Hydrated Lime Production Line
Lime rotary kiln Introduction
Lime rotary kiln is a key equipment of lime calcination production
process. It has the characteristics of wide combustion space and
thermal field, which can fully burn the fuel, and has a uniform
temperature field as a heat exchange device, which can meet the
requirements of limestone calcination. And as a reactor can meet
the heat, temperature and time requirements of lime formation.

Lime rotary kiln is a vertical preheater rotary kiln. The kiln
cylinder is made of high-quality carbon steel plate and the
cylinder is on the wheel support device. A large gear ring is fixed
in the transmission part of the cylinder, and the cylinder rotation
is realized by the frequency conversion speed regulating motor
driving the reducer, the pinion gear, and the large gear ring.
The limestone is preheated by the high-temperature flue gas of the
preheater and enters the rotary kiln body through the transfer
chute. The fuel is injected into the kiln body from the kiln head
by the burner for combustion. Due to the inclination and slow
rotation of the rotary kiln cylinder, the material rolls along the
cylinder and moves toward the lower end of the kiln head. After
further preheating, decomposition, high temperature firing and
other processes in the kiln, it is calcined into quicklime, and
then enters the vertical cooler from the lower part of the kiln
head discharge device.
Our Advantages
1. Advanced Technology: The calcination process adopts pre-heater+
rotary kiln+ vertical cooler system, it can reduce the fuel
consumption 40%, and increase output capacity 30% due to reuse the
waste gas in the system.
2. High Automation Level: The Production line is arranged with
temperature and pressure monitoring instrumentation, operating
parameters of the computer display, the production line can adopt
the advanced computer control, to achieve automatic operation of
the entire system.
3. Mature Experience: We have professional engineer team, mature
experience, and over 100 successful project cases from home and
abroad, to maximize your investment costs and meet the customized
solution demand.
4. Good dust collecting treatment: The cyclone dust collector and
pulse bag filter can control the dust emission is lower than China
standard.
