VERTICAL SHAFT KILN





Technical Data

 

Capacity: 50-500(t/d)

 

Fuel: Mixed Fuel,Gas

 

Raw Material: bauxite, laterite, iron ore, Lime

 

Application: Cement Palnt, Active Lime Plant

 

 

ADVANTAGE

 

1. The shell of kiln use four layer refractory in vertical masonry, good effect of thermal insulation, the temperature of shell will be controlled higher 60℃ than environment, save energy remarkably.

2. Minimum decrepitation of solid products and minumum erosion of refrectory linings due to slight movement of particles relative to each other

3. Use of alternative fuels like low volatile coal, petroleum coke, lignite etc. 

4. Use of alternate raw materials like bauxite, laterite, iron ore, Lime, Sea Shells etc.

5. Less cover area, because the vertical kiln in vertical layout, feeding use the single bucket elevator in high angle layout, each functional area is decorated compact, greatly reduces the cover area.

6. Simplicity of construction and operation, Low initial cost

7. High thermal efficiency & high volumetric efficiency

 

INTRODUCTION

Lime vertical shaft kiln, is used for calcination limestone, it's the most important equipment in lime production line. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, it was widely used in metallurgy, construction materials, calcium carbide, nanometer calcium carbonate, aerated concrete, sugaring, etc. It is especially suitable for the production Nanometer calcium carbonate. Investigate its reason that the concentration of CO2 in flue gas jet can reach more than 35%, CO2 recovery cost is low.

PROCESS

 

1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating.

 

2. Catch wheel: including two kinds of mechanical wheel and hydraulic pressure.

 

3. Gears: single or double. Control the rotating speed by variable motor, DE machine and frequency variable motor. Be reliable, energy saving and efficient.

 

4. Cylinder tyre bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple. Replacement is convenient and won’t hurt cylinder.

 

5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good.

 

6. Kiln head hood: including stationary type and flexible type.
