PROBLEM TO BE SOLVED: To provide a roll mill which can perform ink milling and dispersing of material to be treated so as to effectively prevent re-coagulation of the material to be treated, the material to be treated being prepared by mixing fine powder, nano particles or the like in liquid, and which is suited to pulverizing and dispersing of the fine powder, nano particles or the like, and to provide a method using it. SOLUTION: A roll mill body includes a rear roll 2, a middle roll 3 and a front roll 4. An ultrasonic horn 7 for irradiating the material to be treated in a bank 5 with ultrasonic is provided in the bank 5 formed of the rear roll 2 and middle roll 3. The ultrasonic horn 7 is vertically movably formed to adjust a distance from the liquid level of the material to be treated based on the detection by a displacement sensor 12.
