the grinding fineness ranges between 75% and 90% passing 0.074 mm, the specific surface area of the particles ground by HPGR is only slightly larger than that of particles ground by wet ball mill, approximately equal to those ground by jaw crusher and wet rod mill, and less than that of the particles ground by dry ball mill. When the grinding fineness rises above 95% passing 0.074 mm, the particles......
, the wet ultra-fine grinding by stirred mill is also used to increase modification effect. It has been used in the modification of some minerals, such as wollastonite [16] and tourmaline[17]. In this study, surface modification of calcium carbonate particles with sodium stearate(SDS) incorporated with the simultaneous wet ultra-fine grinding in stirred mill was described, and the influence......

Characteristic analysis of grinding process The hematite grinding process studied in this paper operates in a closed loop. Figure 1 shows the flowsheet of this wet hematite grinding process: To begin... is recycled back to the mill for regrinding. The overflow slurry is the product transported to the subsequent procedure. Figure 1 Flow chart of hematite grinding process (y1: fresh ore feed rate (t/h); y2......
