Abstract: Coal vertical mill, also known as vertical coal mill, is a mechanical equipment used for pulverizing coal. In industries such as thermal power generation, steelmaking, and deep processing of coal, coal vertical mill plays a very important role. This article will introduce in detail the working principle of coal vertical mill.
Raw materials preparation
Before the coal is processed in the vertical coal mill, it needs to be appropriately treated first, such as crushing, screening, and drying. The treated coal will then be fed into the vertical coal mill for grinding.
Coal vertical mills are usually equipped with a coal bunker and a feeding device. The coal bunker is used to store coal, while the feeding device is responsible for conveying the coal to the grinding chamber of the coal vertical mill.
Grinding chamber
The grinding chamber of the coal vertical mill is composed of components such as grinding rollers, grinding discs, classification devices and transmission devices. During the grinding process, the grinding rollers roll along the grinding discs, grinding the coal into fine powder. At the same time, the classification device separates the coal powder that meets the requirements and sends it to the collection system.
Wind power transmission system
The wind-powered conveying system is used to transport the ground coal powder from the grinding chamber to the collector. Under the influence of wind force, the coal powder is conveyed through the pipeline to the designated location.
Collection and Discharge
The ground coal powder is collected and stored by the collector, and then discharged to the downstream equipment or storage bin through the discharging device.
The working principle of the coal vertical mill is based on the conversion of mechanical energy. During the grinding process of the coal, the grinding rollers transfer kinetic energy to the coal, grinding it into fine powder. At the same time, the air conveying system uses the air flow to transport the coal powder to the collector, achieving a continuous and efficient process of coal powder preparation.
Through the detailed introduction of the working principle of the coal vertical mill above, we can understand the significant role of the coal vertical mill in the coal processing industry. With the continuous development of technology, the performance and efficiency of the coal vertical mill will also continue to improve, providing strong support for the development of the coal processing industry.
