Cement rotary kiln is used for calcination clinker from limestone, clay etc to produce cement.Cement production should go through "two grinding process and one burning process" (that is raw material grinding system, clinker calcining system and cement grinding system). Among them, clinker calcining system is a thermal process that burned cement raw meal into cement clinker at high temperature, which is an extremely important key stage in cement production. We supply complete of equipment for 50-3000tpd cement production line.
According to the different production processes of the clinker calcining system, it has the following types:
Dry-Process Rotary Kiln System is mainly composed of rotary kiln, cooler, pulverized coal injection system and fan with gas ﬂow droven and chimney.
1. Stable Product: when the material is calcined, the material can be heated evenly and the product quality is stable;
2. Transmission System: The main transmission system adopts a new type of AC frequency conversion speed regulation technology, and has a large speed regulation range, high efficiency, high speed regulation accuracy, and stable operation;
3. Supporting Device: the bases of the single supporting device and the retaining wheel supporting device are welded, and after the vibration aging treatment is used to eliminate the welding stress, the installation accuracy and reliability of the whole machine can be improved;
4. Optimized Structure: Optimized the overall structure of the kiln head and kiln end sections to solve the kiln end return and dust leakage problems that are common in rotary kilns, and the conveying is more smooth and natural.
