Production process of fully automatic calcium oxide production line
The fully automatic calcium oxide production line relies on intelligent technology to achieve unmanned operation throughout the entire process from raw material processing to finished product output, greatly improving production efficiency and product quality stability. It is the mainstream mode of modern calcium oxide production.
Its production process mainly covers five core links. Firstly, there is raw material pretreatment. Limestone is uniformly transported to the jaw crusher by a vibrating feeder, crushed to 20-40mm particles, and then sent to the vibrating screen for classification by a belt conveyor to remove impurities and unqualified particles, ensuring the purity of the raw materials; Next, the qualified limestone enters the vertical preheater and is preheated to around 800 ℃ using the waste heat from the kiln tail, laying the foundation for subsequent calcination while reducing the energy consumption of the main kiln.
The core calcination process is completed in a rotary kiln, and the preheated limestone is calcined at a high temperature of 900-1200 ℃. The kiln body is precisely controlled by a variable frequency motor to ensure that the limestone is fully decomposed into calcium oxide; The calcined high-temperature calcium oxide enters the cooling machine and is rapidly cooled to below 100 ℃ using a combination of air and water cooling to avoid secondary oxidation and ensure product activity.
Finally, the finished product is processed. The cooled calcium oxide is crushed to the specified particle size by a crusher, and then the dust is removed by a pulse dust collector. Finally, it is quantitatively packaged by a fully automatic packaging machine to generate bagged finished products. The entire process is monitored in real-time through a central control system to achieve precise control of various parameters, reducing labor costs and ensuring a stable calcium oxide content of over 90%, meeting the high-quality needs of fields such as building materials and chemical engineering.
