lime rotary kiln Manufacturer

A lime rotary kiln is a spinning furnace deployed to transform limestone into quicklime with a method called calcination. As the kiln gradually circles, limestone reacts with high temperatures, forcing it to crack down and create quicklime. This process is used in industries such as steel, chemicals, water treatment, and construction, where quicklime is an important part of their different applications. The kiln’s structure entitles for constant heating, dedicated processing, and stable function, making it a crucial element in lime production for heavy-duty industrial use.

Highlights

Highlights of Technomart Lime Rotary Kiln

Lime rotary kilns are the heart of industries like cement, steel, and paper, helping to produce lime (calcium oxide). Here's an analysis of their highlights:

High Efficiency & Energy Savings

Countercurrent Calcination: This technique maximizes heat transfer. Hot gases from the burner orbit against the incoming limestone, preheating it and lowering fuel requirements.
Graded Burst Technology: Enhances the superheated technique, performing entire combustion and undervaluing fuel destruction.
Low-Pressure Loss Vertical Preheaters: These preheaters transmit heat from exhaust gases to the incoming limestone effectively, further promoting power efficiency.
Progressive Burner Techniques: Contemporary burners enhance combustion efficiency and downsize emissions.

Reliability & Durability

Powerful Structure:Lime rotary kilns are built to cater to harsh requirements and high temperatures. They are constructed from high-quality materials and parts.
Long-lasting Refractory Linings: These linings safeguard the kiln shell from warmness and chemical reaction is also prepare it for long life.
Dedicated Drive Systems: Decisive motors and gearboxes assure satiny and nonstop function.
Minimal Downtime: With valid care, these kilns can perform for comprehensive periods by minimizing downtime.

Principle

Working Principle of Lime Rotary Kiln

1 - Material Flow and Preheating:

Limestone Feed: The procedure begins by feeding smashed limestone (calcium carbonate - CaCO3) into the kiln. This is usually accomplished at the taller end of the inclined rotating cylinder.
Preheating: As the limestone transits down the kiln, it experiences superheated gases stroking in the opposite exposure (countercurrent flow). This interaction of heat preheats the limestone, raising its temperature particularly before it precisely goes to the primary burning area. This preheating phase is essential for fuel efficiency.

2 - Calcination:

The Burning Zone: this is the main process of the kiln, in which with the help of fuel generally [natural gas, coal, or alternative fuels] is used to create exceptionally high temperatures ranging from 1000-1200°C or 1832-2192°F.
Chemical Reaction: In intense temperatures, the limestone experiences a chemical response known as calcination. The calcium carbonate (CaCO3) cracks down into calcium oxide (CaO, which is lime) and carbon dioxide (CO2).CaCO3 (limestone) → CaO (lime) + CO2 (carbon dioxide)

3 - Cooling and Lime Release:

Cooling Area: After calcination, the lime reaches the cooling area. Here, it gets cooled down by incoming air, which brings heat to the operation. This preheated air is then fed around into the superheated zone, additionally enhancing energy efficiency.
Lime Discharge: The cooled lime is removed from the kiln's lower end for other processing or usage.

Kiln Zone	Temperature Range
Preheating Zone	500°C to 800°C (932°F to 1472°F)
Calcination Zone	900°C to 1000°C (1652°F to 1832°F)
Cooling Zone	100°C to 150°C (212°F to 302°F)
