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.
