We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of lime shaft kiln
High efficiency and environmental protection intelligent lime shaft kiln, less investment, fast income, energy saving and consumption reduction, high degree of automation, high capacity, high quality of finished products, refractory brick type and masonry is relatively simple and other advantages favored by customers at home and abroad.
Intelligent energy-saving lime shaft kiln is suitable for environmental protection, metallurgy, building materials and other industries.
Production capacity of lime shaft kiln
100-550t/d
Advantageous features of lime shaft kiln
The lime kiln is built with double layers of high alumina refractory bricks and clay refractory bricks. Especially, heat-resistant fiber mat is added between the high-temperature calcination zone, kiln lining and light heat-resistant concrete injection layer to further improve the heat preservation effect and reduce the coal distribution ratio, thus saving energy.
Configuration of refractory materials for lime shaft kiln
The main refractory materials used can be divided into.
High alumina bricks (SK), clay bricks, clay insulating bricks, matching refractory clay, light fillers, a small amount of castables, insulation fiber cotton felt, etc..
Kiln temperature: high-temperature calcination belt, the general temperature at 1150-1200 degrees.
Refractory masonry
Generally speaking, the lime shaft kiln masonry from inside to outside are as follows
1. Working layer: high alumina bricks.
2. Sub-working layer: clay bricks.
3. Insulation layer: clay insulation bricks.
4. Sub-insulation layer: light filler.
5. Insulation fiber cotton felt.
