These Sturtevant Sample Grinders are of the "Open Door" disc type construction and are capable of very fine work, producing products as fine as 100 mesh (coarser if desired) when working on dry, friable, soft or moderately hard materials. They also can work on many hard rocks and ores, but with somewhat reduced capacities.
