Because of its stable performance, strong adaptability and high cost performance, it is widely used in the processing of non-metallic minerals. . However, with the extensive development of non-metallic minerals in the field of ultrafine powder applications, downstream companies have higher requirements for the fineness of non-metallic mineral products.
在实现本申请的过程中,申请人发现现有雷蒙磨通常为四辊雷蒙磨,其研磨出的产品细度较低,一般在500目以下,并且在运行时,机械故障率高,噪音大,整体稳定性也较低,因此这些雷蒙磨无法满足对非金属矿产品的细度要求较高的企业,导致其只能占领较低端的粉体应用市场。In the process of realizing this application, the applicant found that the existing Raymond mill is usually a four-roll Raymond mill, and the fineness of the products it grinds is low, generally below 500 mesh, and the mechanical failure rate is high during operation.
