Working principle and characteristics of Raymond mill
Raymond mill is a sophisticated equipment designed for grinding operations. Its core advantage is to achieve fine grinding of materials through the strong rolling pressure of the grinding roller under the action of centrifugal force. The equipment has a built-in precision grading system to ensure accurate control of powder fineness and meet the strict requirements of different industries for powder fineness.
In addition, Raymond mill is also suitable for non-metallic minerals with Mohs hardness below 7 and humidity within 6%, such as limestone, calcite, etc., showing excellent processing capabilities and a wide range of applications.
Limestone Processing and Raymond Mill Application
Raymond mill plays a key role in limestone processing. First, the raw limestone is crushed by jaw or hammer crusher and evenly crushed into fine particles with a particle size of no more than 30mm.
Then, the crushed limestone is evenly and continuously fed into the Raymond mill through a vibrating feeder. Inside the mill, the grinding roller and grinding ring work closely together to efficiently crush the material to form a fine powder.
The powerful airflow generated by the blower blows up the powder and sends it to the classifier for further fine classification. During the classification process, the fineness of the finished product can be strictly controlled by accurately adjusting the speed of the classifier. Usually, the fineness of the finished product ranges from 80-400 mesh to meet the diverse needs of different industries for powder fineness.
Wide application value of limestone powder
Limestone powder has shown wide application value in many fields. In the field of cement production, limestone powder can be used as high-quality raw material to improve the output and quality of cement. In the plastic industry, the addition of ultrafine limestone powder can reduce the cost of plastics and significantly improve their mechanical properties. In the field of flue gas desulfurization in power plants, limestone powder as a desulfurizer shows high reaction efficiency and effectively reduces sulfur dioxide emissions in flue gas. These application cases fully demonstrate the excellent performance and wide application prospects of Raymond mill in the field of limestone processing.
