Features of Rotary Kiln.
According to their uses, they can be divided into cement rotary kilns, ceramsite sand rotary kilns, kaolin rotary kilns, lime rotary kilns, etc., according to different energy supply effects. It is a gas-fired rotary kiln, a coal-fired rotary kiln, and a mixed-fuel rotary kiln. Based on the structure of a traditional rotary dryer, steam tube.
Sep 05, 2020 The cement plant is one of the most energy-intensive industries, and the rotary kiln consumes significant share of this energy and the amount of consumed fuel has a direct effect on the finished product price (Radwan 2012).The cement plants consume high quantities of power which shape approximately 40 of the total production cost (Chatterjee and Sui 2019 Zanoli et al. 2016b).
Rotary kiln drives the cylinder body to rotate through transmission device and continues to be heated at high temperature to meet the heat transfer requirements of each stage of the clinker formation process and the requirements of heat, temperature and time for the formation of different minerals as well as physical and chemical reactions.
Cement rotary kiln structure. The cement rotary kiln consists of a cylinder block, a transmission, a support device, a roller, a kiln, a kiln seal, a kiln head and a fuel system. The kiln body and the horizontal rotary kiln have a certain inclination. The whole kiln body is composed of a roller support device and a control wheel device to.
