Cement Plant Energy Saving Rotary Kiln Clinker Calcination Equipment
cement rotary kiln
Rotary kiln is also known as rotation kiln. There are many kinds of rotary kiln produced by our company,according to applicable industries, it is divided into metallurgical rotary kiln and chemical rotary kiln; According to the applicable materials, it can be divided into cement rotary kiln, lime kiln, ceramic sand rotary kiln, metal magnesium rotary kiln, bauxite kiln etc.The rotary kiln is composed of barrel, supporting device, catch wheel supporting device, transmission device, movable kiln head, kiln tail sealing device, and coal injection pipe device.
Working Principle
1. With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control the up and down movement of the kiln body.
2. Besides the main driving unit for the driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming.
3. The kiln head adopts housing type sealing and the kiln rear uses axial contact sealing unit so that the reliability of sealing could be ensured.
