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.
Packaging & Shipping
Packaging Detail : The main machinery is in nude packing,and spare
parts in Wooden or steel box standard export packing, suitable for
long distance delivery.

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.
