As the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 49, 50. The parameter setting of the ball mill is shown in Table 1.
Nov 18, 2021 After the jar was closed without purging with inert gas, the jar was placed in a ball mill (Retsch MM 400, 60 min, 30 Hz). After grinding for 60 min, the jar was opened in air and charged with an ...
Sep 22, 2020 5. High Chrome. The grinding sound of the mill is too clear and harsh. The grinding sound value of the electric ear is 158 dB, which is obviously higher than the normal 120 dB standard. It is fully explained that the mill load is too small, the feed quantity is too small, and the steel ball impacts the liner for a long time, resulting in fracture.
