The dielectric and thermal properties of standard enamel and various nanofiller mixed enamel were detailed and analyzed. Nanopowders of ZrO2, Al2O3, CNT and ZnO were used as filler. Ball mill method was used to synthesize various nanofillers such as ZrO2, Al2O3 and ZnO. CNT were synthesized by the process called chemical vapour deposition (CVD).

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's
