There should be no scats at 10 mm unless you are using much too small a grinding ball or the mill charge is much too low. For example, I was told by a client his ball mill feed was P80 = 9mm but when I went to look at the feed belt, I saw this below. The conveyor belt is 15 mm thick, therefore the rocks on it are more like 2030mm.
