Cement Rotary Kiln Oxidation Pelletizing Rotary Kiln
Ⅰ. Basic introduction of oxidation pelletizing rotary kiln(cenment
rotary kiln)
The oxidized pellet rotary kiln is the main production equipment
for calcined pellets in the pelletizing plant. The accuracy of
temperature detection at each point in the rotary kiln is decisive
for the quality, output, energy consumption, cost and safe
operation of the equipment. effect. The rotation of the rotary kiln
brings a lot of inconvenience to the accurate measurement of the
temperature in the rotary kiln. Therefore, choosing an accurate,
economical and practical temperature measurement system for rotary
kiln is an important means to ensure the normal production of
rotary kiln.
Ⅱ. Performance characteristics of oxidation pelletizing rotary
kiln(cenment rotary kiln)
(1) The kiln body is welded by alloy steel plate with very strong
wear resistance, which has excellent wear resistance, compression
resistance and corrosion resistance, and its service life is more
than 3 times that of ordinary rotary kilns.
(2) Gears, sliding bearings and other devices have been specially
optimized to reduce the failure rate and the operation process is
very stable.
(3) The sealing of the kiln head and the kiln tail is relatively
reasonable, the heat loss is greatly reduced, the dust emission is
effectively prevented, and the processing and production
environment is improved.
(4) The volume of the cylinder is relatively large, the processing
capacity of the material is large, and the output is increased by
30%-40%.
(5) The calcination efficiency of zinc oxide is super high, the
calcination is more thorough, and the grade and recycling rate of
zinc oxide are improved.
(6) The energy consumption and electricity consumption are
relatively low, and the operating cost is relatively low.
Ⅲ. Working Principle of oxidation pelletizing rotary kiln(cenment
rotary kiln)
There are refractory brick lining and heat exchange device in the
rotary kiln, which rotates at low speed. The raw material and the
hot flue gas are generally heat exchanged in countercurrent, and
the material is added from the high end of the kiln. Due to the
inclined installation of the cylinder, during the rotation, the raw
materials in the kiln move in the axial direction while turning
over in the circumferential direction. The burner injects fuel at
the low end, and the flue gas is discharged by Gao Rui. The raw
materials are heated during the moving process, and after physical
and chemical changes, they become qualified products and are
discharged from the low end.
Ⅳ. Characteristics and practical significance of oxidation
pelletizing rotary kiln
Oxidation pellet rotary kiln has the characteristics of strong
adaptability to raw materials, advanced technology and good pellet
quality. The development and production of pellets can meet the
demand for raw materials after blast furnace overhaul, solve the
problems of insufficient clinker, high outsourcing cost and
unstable quality, and reduce production costs; Reasonable, it is
conducive to the stable and high output of blast furnaces, and the
coke ratio is reduced; and the project investment is small and the
construction is fast, which not only has good direct economic
benefits, but also brings obvious indirect economic benefits to the
company's blast furnace production, and provides some employment
for the society. opportunities and have certain social benefits.
