The size of the grinding fineness represents the particle size of the finished product after the Raymond mill grinds the material. It is one of the important parameters for users to purchase a Raymond mill. So during the operation of the equipment, what factors will affect the grinding fineness of the Raymond mill?

  1. Hardness of grinding materials

  For different materials, their hardness is different, and the hardness directly affects the grinding difficulty and grinding fineness of Raymond mill, because the harder the material, the more difficult it is to grind, so it is recommended that When using the Raymond mill, the user should properly mix the ore and try to ensure that the size of the materials is uniform to ensure the fineness of the grinding.

  2. The size of the opening of the grader

  In many Raymond grinding production lines, if the size of the classifier opening cannot be adjusted appropriately during the installation process, the grinding operation and grinding fineness may be affected. Therefore, it is recommended that users pay attention to checking the opening size and height settings of the classifier during the installation and production of Raymond mill.

  3. Analyze machine blade wear

  In the grinding and powdering operation of materials by Raymond mill, if the blades of the analyzer are severely worn, the fineness of the materials will become coarser after grinding, which will affect the quality of the grinding. At the same time, when the blades of the analyzer are severely worn, It will also affect the overall production performance of the Raymond mill and even shorten the service life of the equipment.

  4. Wear of wearing parts such as grinding rollers and rings

  As the grinding operation continues, the grinding roller and ring of the Raymond mill, as parts that are in direct contact with the material, are bound to experience varying degrees of wear during the long-term grinding process. Once the grinding roller and ring are seriously worn , will affect the grinding fineness of Raymond mill.

  5. Mill fan speed

  When the air volume of the high-pressure Raymond mill fan is insufficient, the fineness of the discharged product will also become coarser. Because during the grinding and powdering process of ore materials, if the air volume of the fan is weak, it will not be able to blow the mineral powder material to flow well, thus causing the mineral powder material to be hindered in the circulation process, and the fineness of the finished product will become coarser. Phenomenon. Therefore, appropriate adjustment of the air volume regulating valve according to the actual production is an important measure to ensure the fineness of the finished product discharged from the high-pressure Raymond mill.
