Cement Rotary Kiln Metallurgical Rotary Kiln
1. Basic introduction of metallurgical rotary kiln(cement rotary
kiln)
Metallurgical and chemical kilns are mainly used for magnetization
roasting of lean iron ore in iron and steel plants in the
metallurgical industry; oxidative roasting of chromium and nickel
iron ore; roasting of high metallurgical ores in refractory plants
and clinker and aluminum hydroxide in aluminum plants; roasting of
chromium ore and chromium in chemical plants Mineral powder and
other minerals.
The research and development and application of the active lime
field where the industrial kiln is located has achieved fruitful
results. It has advanced calcination laboratory and industrial
simulation laboratory, complete system technology of active lime
and key equipment technology. field is applied.
2. Cement kiln classification(cement rotary kiln)
Cement kilns are mainly used for calcining cement clinker, which
are divided into two categories: dry production cement kilns and
wet production cement kilns. Metallurgical chemical kilns are
mainly used for magnetization roasting of lean iron ore in iron and
steel plants in the metallurgical industry; chromium and nickel
iron ore oxidative roasting ;Refractory plant roasts high alumina
vanadium ore and aluminum plant roasts clinker, aluminum hydroxide;
chemical plant roasts chrome ore and chrome ore powder and other
minerals. Lime kiln (ie active lime kiln) is used for roasting iron
and steel plants, ferroalloy plants Active lime and lightly burned
dolomite used.
3. Technical characteristics of metallurgical rotary kiln(cement
rotary kiln)
(1) The kiln body of the metallurgical rotary kiln is rolled and
automatically welded with high-quality killed carbon steel or alloy
steel plate;
(2) The belts, supporting rollers and open gears of the
metallurgical rotary kiln are made of alloy cast steel;
(3) The sliding bearing of metallurgical rotary kiln adopts large
clearance non-scraping bearing;
(4) The transmission device adopts hard tooth surface reducer,
elastic diaphragm coupling, DC motor driving;
(5) The metallurgical rotary kiln adopts hydraulic blocking wheel;
(6) The kiln head and the kiln tail are respectively sealed by
scale lamination and cylinder compression;
(7) The metallurgical rotary kiln is equipped with a slow drive
device.
