Estimation of Grinding Time for Desired Particle Size

网页2020年1月3日  Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energy-intensive process [1,2,3,4]. In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
