While milling time progresses, more mechanical energy is transferred to the lignocellulosic biomass through collisions between the grinding balls and between the grinding balls and the surface of the mill chamber . Thus, a significant reduction in particle size and crystallinity usually occurs with increasing milling time .

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 time increased to 6 h, and then decreased when further increasing the ball-milling time.
