Ren H.,Benz H.U.,Chimal V. O.,Corral G. M.S.,Zhang Y.,Jaramillo V. D.,Zoz H. 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
The present paper is a parameter study of zinc flake production using a Simoloyer CM01 horizontal high energy rotary ball mill. The manufactured flakes have a dimension in thickness (t) < 1μm and diameters (d) 5-100 μm, consequently a ratio d/t up to 200. The flake geometry is mainly controlled by the variation of process parameters such as rotary speed of the rotor, ratio of powder/ball charge, load ratio of the system, process temperature, operating model and the quantity of process control agent (PCA). The Zn flakes were characterized by SEM, tap densitometry, laser diffraction and water coverage measurement.

High Energy Milling (HEM) is applied for the grinding of cement and this can lead to substantial refinement (<2μm) and mechanically activation of the powder particles. The present paper reviews the preliminary studies, explains the novel technique and suggests the route into commercial application. Particular attention is paid to wear results with an applied unit where no substantial wear was found after 4000 h of operation.
