Natural Gas Vertical Shaft Kiln Machinery For Calcination Dolomite Lime
Vertical Shaft Kiln Introduction:
Vertical Shaft Kiln is used for the calcination of cement clinker, limestone, bauxite and other materials. The vertical kiln manufactured by ZK group has the advantages, such as modern design, new technology, environmental protection,energy saving, higher machanization and automaticity etc. We offer 50 TPD to 300 TPD vertical shaft kiln on turnkey basis for cement and active lime plant, which is the advanced technology available world wide for small & medium entrepreneur.
Vertical Shaft Kiln Advantages:
1.The shell of Vertical Shaft 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.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.
3. Vertical Shaft Kiln 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.

Vertical Shaft Kiln Technical Parameters:
Lime Vertical Shaft 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.
