High-efficiency HP bowl coal mill is a new type of energy-saving product launched by our company, which aims to solve the technical problems of low output and high energy consumption of industrial mills. It is developed on the basis of traditional HP vertical medium-speed coal mills. The basic frame and roller loading method have been retained while enhancing the roller structure and dynamic separator. This improvement significantly reduces the circulation rate of pulverized coal, increases the mill’s output, and reduces the ventilation resistance of the system. These advantages are clearly evident when compared to conventional HP pulverizers.

Material: The coal vertical mill can be used for grinding bituminous coal, anthracite, lignite, petroleum coke, coke, asphalt and other materials; limestone, lime, barite, talc, gypsum, cement raw material, slag, cement and other industrial grinding fields.
Application field: It is a kind of grinding equipment integrating drying, grinding and powder selection, which is widely used in coal chemical, thermal power, steel and non-metallic mineral grinding fields.
The high-efficiency HP bowl coal mill consists primarily of a falling coal pipe, a gate valve for exporting pulverized coal, a dynamic separator device, a spring-loaded device, a high-efficiency roller device, a bowl-grinding device, and stone coal collection devices. Additionally, it includes transmissions, bases, housings, and other components. The dynamic separator serves as an efficient and energy-saving device for powder selection. The roller device is responsible for grinding and crushing the material. The grinding device is securely mounted on the output shaft of the speed reducer, serving as the area where the roller exerts force on the material. A spring-loaded device plays a crucial role by providing grinding pressure to the roller, ensuring sufficient force to crush the material effectively.
The electric motor drives the grinding disc through the reducer, so that the material falls on the center of the grinding disc from the inlet, while the hot air enters the mill from the inlet. Under the action of centrifugal force, the material is brought up to the edge of the grinding disc by the high-speed airflow of the wind ring. The large particles fall directly to the grinding disc for regrinding. When the material in the airflow enters the upper separator, the coarse powder falls from the cone bucket to the grinding disc for regrinding under the action of the rotating rotor, and the qualified fine powder comes out of the mill together with the airflow and is collected by the dust collection device, which is the product. Materials containing moisture are dried in the process of contact with hot gas. By adjusting the hot air temperature, it can meet the requirements of different humidity materials and reach all the required product moisture. By adjusting the separator, the HP bowl coal mill can achieve the required coarseness and fineness for different products.
