Ball Mills / Vacuum Mixers. The MSK-SFM-1 ball mill has four ball grinding tanks installed on one turning plate. When the plate rotates, the tank axis makes planetary rotation in opposite directions and the balls in the tanks grinds and mixes samples in high speed movement. The product can smash and blend various products of different materials ...
Moreover, ball milling was stopped for 10 min every 30 min of working to release the heat. The typical ball-mill rotation speeds were 250, 300, 350, 400, 450 and 500 r.p.m.
Methods. To obtain nanodispersion particles within the metal matrix, MA was operated in a ball milling with stainless steel balls and vials. The mean ball diameter for the stainless steel balls was 10 mm. Ball-to-powder ratio is fixed as 10:1 for MA at 300 rpm with toluene as a process control reagent medium for 20 h inside Fritsch Pulversitte-5 planetary ball mill.

Cu/ZnO catalysts (with a Cu/Zn atomic ratio of 30/70) have been prepared by high intensity mechanical mixing of copper and zinc oxide powder in air and under vacuum. During milling in vacuum gradual amorphisation of the constituents occurs, as evidenced by broadening of the Cu0 and ZnO diffraction peaks in XRD, but the two original phases remain. The result of such treatment is a catalyst with ...
