Product introduction

Rotary kiln is what we called rotary calcining kiln in daily life. Because the kiln will rotate while working, it is called rotary kiln. This kind of equipment is widely applied to cement, metallurgy, chemical industry and limestone. Therefore, there are many other kinds of rotary kilns, such as metallurgy rotary kiln and cement rotary kiln. It belongs to building material equipment.

Technological process of rotary kiln, 
1.     No matter what kind of rotary kiln, they hold similar technological process. In order to expand heat transfer area, there is always chains hung at kiln tail in order to speed up evaporation. For wet rotary kiln, add water to raw material mill. Make raw material to slurry with 30% to 40% moisture content; qualified slurry will be sent to rotary kiln by feeder at kiln head. Clinker will be cooled by cooler and be sent to clinker storage. After being dried and grinded, raw coal will be combusted for supplying heat.
2.     Features for wet rotary kiln: Raw materials are made into slurry. Therefore, wet type rotary kiln holds great adaptability. The ingredients of raw materials are uniform and stable. Clinker is with superior quality and high class. In the grinding process, there is less dust and fly ash. About 30% to 40% moisture content will be evaporated, which will cost large amount of thermal value which accounts for one second or one third of total cost which is higher than vertical kiln and dry type kiln. Owing to high thermal cost and water cost, wet type kiln has been abandoned gradually by china.

 

Main structure of rotary kiln:
Rotary kiln mainly consists of three parts:
1.   Kiln shell: can be seen from the outside;
2.  Tyre ring: a main part of rotary kiln; used to fixing kiln shell;
3.  Thrust roller: lime the up and down movement of rotary kiln; because it is wider than tyre ring, in order to realize even abrasion, there is no tyre ring at the surface of tyre ring.
