For each grinding test, the mill was first loaded with a 1.86 kg mass of ball mix and a 150 g mass of feed sample material.A volume of 64.0 ml tap water was then added to the mill charge in order to make a 70 wt.% pulp density.Four mono-sized fractions of quartz and chlorite(− 2 + 1.19 mm, − 1.19 + 0.5 mm, − 0.5 + 0.25 mm, − 0.25 + 0.15 A QM-3SP2 planetary ball mill manufactured by Nanjing University Instrument Corporation (Nanjing, China) was used for the ball milling experiments. Mirex powder was firstly mixed with various reagents at a mass ratio of 1:24, including CaO, CaO + SiO 2, Fe, Fe + SiO 2, and SiO 2, thus yield to feed-in mixtures.Mechanochemical destruction of mirex co-ground with iron and quartz

During the milling of an 122 A.W. Weeber and H. Bakker / Amorphization by ball milling amorphous and an elemental powder in the planetary ball-mill of Weeber et al. [57] the powder remains as such during the whole milling period. Consequently, the contact surface of a powder particle and a ball will be small.Abstract. The specific rates of breakage of quartz have been studied in three tumbling ball mills, two of 195 mm i.d. and one of 0.6 m i. d., as a function of fractional ball and powder loading. It was found that power results from a small mill with small lifters were anomalous, probably due to slippage, so that results reported previously fromFurther studies of ball and powder filling effects in ball
