The metallurgical pellet industry occupies a vital position in modern steel production. With the continuous growth of global steel demand, the demand for high-quality pellets is also growing. As a high-quality ironmaking raw material, pellets have the advantages of high grade, good strength, and uniform particle size, which can improve the production efficiency of blast furnaces and reduce energy consumption. In the production process of metallurgical pellets, grinding is one of the key steps. Iron ore is the main raw material for metallurgical pellets. It usually needs to be ground to make its particle size meet certain requirements for better pelletizing and sintering.Additives (such as binders, bentonite, limestone, etc.) also need to be ground to ensure that they are evenly dispersed in the iron ore to enhance the strength and stability of the pellets. Coal powder, as a raw material for green ball calcination, can provide more uniform heat distribution, help improve the efficiency of pellet calcination, and ensure that the pellets reach the ideal hardness and strength during the calcination process.
Grinding stage 
Material of suitable size is fed into the main machine for grinding, and the fine powder after grinding is sent to the analyzer for grading under the action of the air flow of the fan, so that the fine powder with qualified fineness can enter the collecting stage.
Collecting Stage
The dust gas enters the cyclone collector through the outlet pipe. Under the action of centrifugal force, most of the finished fine powder is separated. Redundant gas is discharged and sent to pulse dust collector. Then it becomes clean gas. Fine powder collected by cloth bags is transported to the conveying stage through screw conveyor.
Conveying Stage
The finished powder collected by dust collector and cyclone collector is sent by screw conveyor to the next process or into finished product tank.
According to the raw material feed fineness, finished product fineness, purpose and other factors, SBM can help customers reasonably select the grinding and powder selection process, and determine the type, model and quantity of grinding mills according to production capacity and other requirements.
As a professional powder equipment manufacturer, SBM has launched a comprehensive solution for green and intelligent grinding equipment. Through fine grinding of iron ore, bentonite, limestone, coal powder, etc., it not only improves the quality and performance of pellets, but also conforms to the development trend of green, energy-saving and environmental protection in the metallurgical industry.
