<p>PROBLEM TO BE SOLVED: To provide a jet mill capable of simplifying a jet pulverization method for a moist or wet pulverization target in the jet mill and being configured at lower cost.SOLUTION: A jet mill 1 selects at least one operation parameter among front pressure, opening pressure, and inlet temperature so as to be suited for implementation of pulverization and drying. At a time of this pulverization and drying, a moist or wet pulverization target is pulverized to have a final fine particle degree and dried to have a predetermined residual water content so as to obtain a finished product simultaneously satisfying the predetermined final fine particle degree and the predetermined residual water content in the jet mill 1. By appropriately selecting at least one operation parameter among the front pressure, the opening pressure, and the inlet temperature, an operation medium necessary amount for the pulverization per reference amount is set either larger than or equal to an operation medium necessary amount for the drying per reference amount, and the finished product having the predetermined final fine particle degree and the predetermined residual water content is output from the jet mill 1.</p> |
