The final grain size of grinding products depends on the nature of the minerals and the requirements of the beneficiation process. After being determined by beneficiation tests, it is generally not easy to change. Therefore, for Raymond Grinding accessories grinding operations, only grinding products with sufficient dissociation and crushed particles can be produced on the premise of ensuring the fineness of the grinding, avoiding excessive crushing. The extra energy consumption. However, it should be noted that since the fineness of grinding required for laboratory flotation tests is not measured by the hydration method and flotation is performed in a laboratory flotation machine, it is produced at the flotation plant. The appropriate grinding grain size can usually be thicker than that measured in laboratory tests. As for the Raymond mill grinding powder size of various Raymond mill models is appropriate, it should be decided after the production of comparative tests.
