New Type Durable And Energy Saving Vertical Lime Shaft Kiln Direct From Manufacturer



Vertical Lime Kiln Introduction:

Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. 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. The vertical kiln was manufactured by ZK group with modern new technology, which is an environment protection, save energy, higher machanization and automaticity, quite modern lime kiln. Because it adopts the modern technology, make full use the cheap energy, especially pollution of gas for environment harmful (such as conventer gas, blast furnace gas, calcium carbide furnace tail gas) as the energy, turn waste into wealth. Thus will protect the environment, and produce the high quality lime with lowest cost. To use this new technology enterprise, economic benefits have increased significantly.


It should be pointed out that the kiln type 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.

Lime Vertical Kiln Our Advantages:

1. Save energy; There are preheating zone, calcination zone, cooling zone from the top to bottom of kiln inside. The cooling air blow into the cooling zone from the bottom, though the heat transfer, the goods were cold, and the cooling air was heated, then put into the calcination zone with the heat for burning, thus reduce the energy consumption. The flue gas from the fuel after calcination enter into the preheating, make the material heat to pre-dissociation temperature. The flue temperature fall to 170-300℃, then come out from the kiln.


2. 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.


3. Long service life of refractory, the material not directly crash the work surface of refractory, but its fraction with work surface by gravity setting. Thus it greatly reduces the wear rate of refractory, the refractory will be used in 6-10 years in normally.


4. 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.

Lime Vertical Kiln Structure:

In order to guarantee the quality and capacity of lime, finalize the fully automatic production during the production, the special and main equipment for the kiln as follows:


1. Limestone batching electric weighing system

Required limestone and coal mixed as the feeding material in the kiln processing. The ratio of two mixed material is very important, the two weighing system can accurately measure the raw material quality, and mix them with special batching method. In addition, if any changeable in particle size of raw material or calorific value of coal, should adjustable the ratio of two raw material, operation the computer will finalized in control room.


2. Intelligent master controller

Main winch system, make the rotation motor change into frequency control of motor speed. During the handcart route from feeding to 0 ~ 6 m after adopt step-less speed 6 m is set to 1 m/s running smoothly, terminal schedule 6 m for step-less speed running ahead of time, until discharge. This design ensures the skip smooth operation, greatly reduce the vibration and the failure rate of inclined bridge. The elevating capacity will improve 60% than no frequency control of motor speed. Make the main winch system greatly reduced maintenance. The handcart running status and adjustment wire rope length no more downtime. Practical life of wire rope improve more than 3 times.


3. Rotary distributing devices

The key of feed material inside kiln ensure the uniform flat, rotary distributing devices could make the raw material even scattering into the material surface, the shape of surface is adjustable. Application of frequency conversion governor, PLC control, makes the fabric are accurate and reliable. The case of the key structure, such as cylinder, baffle, cloth guide groove, and tablets, etc. With high temperature resistant, corrosion resistant stainless steel. Rotating parts with special high temperature resistant surface bearing, makes the equipment operation and reliable, and can in a terrible environment without any medium. For the high quality of the calcined limestone provides a good technological conditions.

The special structure of the case after mixing limestone and coal can be scattered to the material surface. Greatly reduced due to uneven fabric in furnace nodules, waste of fuel. Like Shuicheng steel, Jinan steel and other units in the replacement after this kind of case, after the measured production ash per ton coke saving (or coal) in more than 15 kg.

4. Pan discharging lime machine

This equipment is mainly composed of motor, reducer, transmission shaft, rotary blade, and other parts.


5. Two section seal valve lime discharging machine

In the vertical kiln production, to ensure the quality and quantity of finished products of lime, must be kept combustion air continuous production. The two section seal valve lime discharging machine is one of key equipment during the efficient automatic discharging lime. A full set equipment is composed of upper and lower two dampers connection in series. Each damper is consists of damper box, damper, damper shaft, damper spacer, inspection door, pneumatic system and lubrication system. Two damper take turns to open and close alternately, discharge the continuous fall lime to the final belt conveyor. Due to the damper seal during the discharging lime, make the combustion air continuously supplied, no any link from the bottom.
