Ball Milling

Ball milling is one of the earliest approach for BNNTs synthesis [59]. The process involves extensive ball milling of boron powder for a long period of time (up to 150 h) in NH 3 gas followed by annealing at high temperature (up to 1300 C) in N 2 environment.

To Install the Ball Mill Correctly

A ball mill can be installed on top of the concrete base when its compressive strength is up to more than 75%. Before installation, check the quality of the basis to ensure that concrete is not affected by the strength of the defect, the number and position of the reserved hole meets the requirements, and the reserved holes have no water, without oil stain.

Calculation of Top Grinding Media Size -Ball Sizing

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batch-grinding tests interpreted in the content of population balance models (Lo and Herbst 1986).
