## Simulation of wet ball milling of iron ore at Carajas

The tests were made in a steel cylindrical ball mill of 250 mm internal diameter (D T) and 250 mm length (L T) fitted with eight symmetrically located horizontal lifters (see Table 1) and smooth end walls, with one end wall removable and locked in place with a quick release locking clampThe media were stainless steel ball bearings of 254 mm (1 inch) diameter, with aThe wet ball mill has a low noise, and low environmental pollution The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill TheWhat Are the Differences between Dry and WetOleg D Neikov, in Handbook of NonFerrous Metal Powders, 2009 Tumbling Ball Mills Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale Grinding elements in ball mills travel at different velocities Therefore, collision force, direction and kinetic energy between two or moreBall Mills an overview | ScienceDirect Topics
