Re: VERTICAL ROLLER MILLS

Equipment suppliers must have mentioned in their manual;if not you can ask them.Optimun feed size (neither too big nor too small) and nozel velocity will have to evolved by apprpriate logging and monitoring of process & quality and out put data.Well, the Q. is qualitatively answered and not quantitatively.
