1. Summary of the cylinder rotary kiln

Cylinder rotary kiln is one of the rotary kilns, which is mainly used for calcining the cement clinker. It is the key equipment in dry process cement production line. The cylinder rotary kiln mainly consists of the cylinder, the supporting device, the wheel supporting device with gear, the transmission device, the lubricating device, the active kiln front, the sealing device of kiln end, and other components.

2. Performance characteristics of the cylinder rotary kiln

1) The cylinder rotary kiln has the features of simple structure, reliable operation, and high automatic control degree.

2) The cylinder rotary kiln has an advanced preheating system, high kiln speed, and high unit volume production.

3) The cylinder rotary kiln has a good seal effect, achieving the full use of the waste heat; simple and effective dust extraction system, realizing high working efficiency, low energy consumption, low running cost and high benefits.

3. Working principle of the cylinder rotary kiln

The combustion of pulverized coal (gas) in the rotary kiln generates the heat. The heat heats the material through the gas conduction or the radiation. At the same time, the kiln body keeps rotating in accordance with the inclination and the rotational speed of the design. The raw material is also periodically tumbling forward in the kiln, so the material is transported from the charging port to the discharging port, which ensures that the raw material is calcined into the qualified clinker through passing the cylinder rotary kiln, achieving the purposes of high yield, high quality and low energy consumption.
