Active Lime Kiln

Product features

Performance characteristics:

This kiln type structure is advanced, reliable kiln combined scales seal at both ends so that air leakage coefficient is less than 10%; furnace lining using composite refractory to reduce radiative heat loss full use of waste heat and preheat the kiln can be secondary air to more than 700 ?, and saves the energy.

Technical characteristics:

1. Advanced structure, low loss of shaft preheater can increase the preheating, after preheating limestone kiln decomposition rate of overnight, and direct access to 10-15mm fine grade limestone;

2. reliable kiln combined scales seal at both ends. Air leakage coefficient is less than 10% the use of composite refractory to reduce radiative heat loss;

3. fill type, separate ventilation round or square vertical cooler, cooler lime 800C+ ambient temperature the temperature, ease of transportation, storage, and secondary air preheating kiln to 7000C above, less moving parts and special materials.

Product principle

Coal powder (gas) in kiln within burning produced heat, heat through gas conduction or radiation on material for heating, while with kiln body according to design of slope and speed kept turned, raw materials also in kiln within periodic of roll forward, to put raw materials by into material end conveying to out material end, while guarantee in raw materials through rotary kiln of time within will its calcined for qualified clinker, reached high yield, and quality, and low of purpose.
