Cement Plant Production Machine Vertical Shaft Lime Rotary Kiln
Introduction of Rotary Lime Kiln
The rotary kiln produced has advanced structure. It can effectively
improve preheating effect with its low resistance vertical
preheater. After the material is preheated, the feeding
decomposition rate can reach 20%-25%, thus can directly make use of
10-15mm fine fraction materials. The reliable airtight two-ends
combination squama make the air leakage factor under 10%. The usage
of compound refractory reduces radiation loss.Rotary kiln belongs
to building material equipment, which can be divided into cement
kiln,metallurgy chemical kiln and lime kiln according to different
materials.
Structure of Lime Rotary Kiln
Lime kiln consists of kiln body,feeding device,cloth device,
burning device,discharge device,electrical equipment,instrument
control equipment,dust removal device,etc.
Different forms of lime kiln,its structure and calcination,process
basic same,but the value of equipment has the very big
difference.Of course use effect is distinct
Working Principle of Lime Rotary Kiln
Rotary kiln cylinder composed of steel plate, cylinder body with
build by laying bricks or stones of refractory lining, and
horizontal line into slope, three belting leather in each block
supporting device, in the material near the end belting leather
across the inner cylinder with tangential spring plate fixed on a
big gear ring, which is a small gear meshing. During normal
operation, the main drive motor is transmitted to the open-type
gear device by the main drive motor, which drives the rotary
kiln.Materials are calcined from the end of the kiln. Due to the
effect of tilting and slow rotation of the cylinder, the material
is along the circumference of a circle and tumbling along the axial
direction (from high to low) mobile, continue to complete the
process, and generate the clinker kiln hood into the cooling
machine cooling.The fuel is sprayed into the kiln by the kiln head,
and the waste gas and materials produced in the furnace are
exchanged for impact crusher, which is exported by the kiln tail.
