Raymond Mill

Raymond mill is a grinding mill with a long history, and it is the ancestor of the trapezium mill. It provides the needed flexibility to economically and efficiently process a wide variety of materials.

The main parts of Raymond mill is grinding roller, grinding ring, grinding roller assembly, the plum flower frame, air flue, coupling, perching knife and so on.

Materials: Barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorspar, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, etc.
Applications: Metallurgy, chemical engineering, building materials, mining, pharmacy, cosmetics and other fields

  • A Raymond Mill covers a small area, and can complete powder preparation efficiently and the fineness of the finished product is uniform and the screening rate can be as high as 99%;

  • The introduction of foreign centralized control technology in the electrical system can realize the unmanned operation of the workshop and make the maintenance simple and convenient.

  • Imported high-quality steel is used for important parts. High-performance wear-resistant materials are used for the grinding parts.

Working Principle

Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, SBM arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.
