Continuous Rod and Ball Mill Sepor, Inc
The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill. The spiral classifier is popular in pilot plant grinding due to the ease in which the oversize is returned to the mill when a specific grind size is your target. The mill is capable of both wet and dry grinding. Sepor’s 16What are the differences between ball mill and rod mill,Center and side discharge rod mill can grind ores coarsely because of its structure. This kind of rod mill can be used for wet grinding and dry grinding. "A rod mill is recommended if we want to properly grind large grains, because the ball mill will not attack them as well as rod mills will." ①. End and side discharge rod mill
Particle size reduction, screening and size analysis
Also wet grinding can be used when the final product size is extremely fine since production of nanoparticles is possible with wet grinding. Pigments for inks and paints might be ground in the medium in which they are to be suspended. Wet grinding often takes place in ball, pebble or rod mills.
