The rotary furnace is a common type of kiln equipment in production. However, the general public has very little understanding of this kiln equipment. To truly understand the rotary furnace, we must understand its working principle in order to maximize its function in future production processes. Today, with this question in mind, let's take a look at the working principle of the rotary furnace together Liba
A rotary furnace is a combustion equipment in which coal powder is burned to generate heat; It is also a heat transfer equipment, where the raw materials absorb the heat of the gas for calcination. In addition, it is also a conveying equipment that transports raw materials from the feed end to the discharge end. The three aspects of fuel combustion, heat transfer, and raw material movement must be coordinated reasonably in order to ensure that the heat generated by fuel combustion can be transmitted to the raw materials in a timely manner during the passage of the raw materials through the rotary kiln, achieving the goal of high yield, high quality, and low consumption
The rotary furnace developed and designed by Xianyang Ceramic Research Institute is a process of calcining materials by feeding raw materials from the cold end of the kiln. Due to the kiln's certain inclination (usually 3-3.5%), with the help of continuous rotation trajectory, the raw materials are continuously moved towards the hot end and stirred in the rotary furnace to mix and react with each other. The fuel is injected into the natural end, and under the assistance of air combustion, it releases heat and produces high-temperature flue gas. The hot gas is driven by the fan and flows from the natural end to the secondary end. The heat is transmitted to the material through flame radiation, convection of hot gas, and conduction of kiln bricks (kiln skin). The material and flue gas exchange heat during the reverse movement, and the material moves forward in the kiln based on the inclination of the kiln barrel and the rotation of the kiln, causing the raw material to be burned into clinker. If a certain filling coefficient needs to be maintained in the kiln, it is necessary to coordinate the kiln speed and feeding speed, and maintain a certain proportion; This is also a process condition for improving production and quality, stabilizing the thermal system, and overcoming agglomeration
