Vertical Preheater in Rotary Kiln

Rotary kiln preheater is a key equipment in limestone calcination system, Most rotary kiln preheater are vertical preheaters. Henan Zhengzhou Mining Machinrery Co.,Ltd (ZK) limestone calcination system is composed of vertical preheater, rotary kiln and vertical cooler, grinding coal machine and other major equipment. Vertical preheater is used for preheating refractory raw materials. ZK vertical preheater is with the advantages of reasonable structure, thermal efficiency and high degree of automation features. It is used with the lime rotary kiln to preheat limestone or dolomite and other raw materials and has been widely used.
Product features:
1 Feed material in preheater body to achieve a safe seal, so that the outside cold air can not enter, which ensures good production process requirements.
2 Preheater internal structure is reasonable, the key parts are selected heat resistant steel and other materials to ensure reliable use.
3 Hydraulic system with reliable performance is used to ensure the smooth operation of the pushing device.
Composition:
Vertical preheater is composed of a feeding device, a preheater ontology, pushing feeding device, hydraulic system, lower the feed chamber, frame the main part.
Working principle：
Raw materials get into flue gas material isolation cover from the feeding chamber and distributed in the preheater ontology between two cylindrical annular reactor material space along the the central points of cone. The 900-1000℃ hot flue gas from the rotary kiln enter into the the entire section of the annular reactor space through the air inlet of the gas collecting chamber, the hot gas exchange heat through the material layer. 600℃materials are successively pushed into the kiln with the pushing device to achieve the purpose of uniform feeding.
Henan Zhengzhou Mining Machinery Co.,Ltd provide rotary kiln preheater which are used in lime production line and metal magnesium production line. We have been working hard for your convenience.
