THE PARTICLE SIZE DISTRIBUTION OF MARBLE ON WET

An investigation has been made of a wet ball milling procedure which depends on the apparent viscosity of the charge increasing during the operation until the balls are held by the charge, and circulate with the mill. By varying the solid: liquid ratio of the charges the mean particle size of the product was changed, and shown to be a linear function of the proportion of solid in the charge ...
