How much money to invest 300,000 t/a active lime kiln production line ?

As steel, calcium carbide and other industries demand a 20% increase in profit incentives lime, lime kiln launched a large number of soil on the market. But the old type production processes and product quality can not meet the needs of modern kiln production, low activity of the product, raw burning, burnt can not be controlled, fuel wastage and serious environmental pollution. Thus, the new environmentally friendly active lime kiln production line will replace the original lime kiln!

Chaeng based on years of mechanical manufacturing experience, successfully developed a new environmental protection lime kiln, has an absolute advantage in terms of production, coal consumption, lime activity, burning loss rate, to customers of all ages.

Host calcination process: lime rotary kiln

Figure: active lime kiln production line process

Qualified limestone (20-50mm) by Lifting and carried into the preheater at the top of the silo.

Preheater top two upper and lower hopper level meter to control the feed amount, and then blanking tube limestone evenly distributed to each of the preheater chamber.

Limestone in preheater kiln flue gas is heated to about 1150 ℃ 900 ℃, about 30% decomposition. By hydraulic push rod pushed into the rotary kiln, the limestone calcined in a rotary kiln decomposition of CaO and carbon dioxide.

After the decomposition of limestone into the cooler in the cooler was bubbled into the cold air cooled to below 100 ℃ discharged. By heat exchange 600 ℃ hot air into the kiln and gas co-firing.

The exhaust manifold through the cooler into the bag filter through the induced draft fan, and then the exhaust fan into the chimney.

A lime cooler by vibrating feeder, bucket chain conveyor, bucket elevator, belt conveyor into the lime finished products.

Production line advantages of high efficiency, environmental protection

1. The higher activity than traditional shaft kiln 30ml

Because the material in the kiln even rolling forward, uniform heating, raw, burnt a lower rate for calcined lime with high activity, under the same conditions, the activity of lime shaft kiln lime production is higher than the average high 30ml, activity of up to 400ml, or even higher.

2. The capacity of up to 1500t / d

Chaeng active lime kiln large-scale production, one active lime production line capacity up to 1500t / d, running in good condition, to provide protection for the steel plant and other enterprises to expand the scale and lower production costs.

3. Automated control reduce labor costs

High degree of automation, using DCS remote control system, the entire line of 2-3 people to operate.

4. good product quality, low birth burn

Uniform product quality, raw burnt burn rate <8%.

5. gaseous fuel, energy saving

Chaeng lime kiln belonging to open firing, high-tech production process, relatively low energy consumption than the old lime kiln, and the use of blast furnace gas and other waste as a fuel more environmentally friendly.
