The ball milling was carried out in a conventional planetary ball mill as well as in a high-energy ball mill. For graphite, our goal is to investigate the ball mill effect, so a high-energy ball mill was used to maximize the change. Whereas for layered graphene, due to the large particle size of the pristine material,

The material to be ground is placed in a stationary, jacketed tank with the grinding media. Carbon steel, stainless steel and chrome steel balls (3/16″ or 1/4″) are commonly used media. The material and media are then agitated by a rotating internal shaft with arms. The final result is a fine, even particle dispersion.

Further increasing the ball-milling time to 8-12 h resulted in serious damage to the CNTs. The tensile tests showed that as the ball-milling time increased, the tensile and yield strengths of the composites increased, while the elongation increased first and then decreased. The strengthening of CNTs increased significantly as the ball-milling ...

The ball mill was characterized by a ball-to-powder weight ratio of 10:1, a stainless steel chamber, and stainless steel balls with diameters of 19 mm, 12.7 mm, and 9.5 mm. The samples were oven-dried and kept at 110 °C in the oven for 24 h to prevent agglomeration and contact with moisture (Abdul Khalil et al. 2011; Rosamah et al. 2016).

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ...
