Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However‚ many customers are confused when they choosing equipments for grinding due to their similar appearance. This paragraph is a brief explanation to the difference of ball mill and rod mill below. The calling name of ball mill and rod mill comes from the different grinding medium. Rod mill is called rod mill because the grinding medium in the barrel is steel rod. Rod mill is usually

distribution of the volcanic emissions‚ a simulation with the Lagrangian Flexible Particle Dispersion Model‚ or FLEXPART‚ while using a beforehand assumed emission term for ash sources‚ as well as an inversion technique‚ was used to improve the results of ash distributions against findings in ash columns1. Since volcanic emissions contain large amounts of different substances‚ “ash” in this case is defined as a particle with radius smaller than 125 µm and is divided into 25 different size bins. During
