3 Necessary Cement Milling Comparison Ball Mill, Vertical Roller

Which cement milling is proper for cement manufacturing? It usually depends on the different types of cement raw material In the real cement plant project, smooth operation is the first element to be considered Today we will compare three kinds of cement milling: vertical roller mill, cement ball mill, and rod millFig 1 shows the XRD patterns of Fe2568 wt%Tm 2 O 3 powder mixtures milled for different time In the XRD spectrum of the original powder mixtures, there are the diffraction peaks of Fe with bodycentered cubic crystal structure and Tm 2 O 3 with cubic crystal structure The diffraction peaks of Tm 2 O 3 and Fe are broadened and reduced Ballmilling properties and sintering behavior of FeTm
