PROBLEM TO BE SOLVED: To provide a roller type grinder capable of increasing a production amount of fine powder while performing a stable conventional operation with a large-sized machine when grinding adhesive substances such as limestone (CaCO<SB>3</SB>). SOLUTION: The roller type grinder is used for grinding raw material by performing relatively turnably operation in the circumferential direction with a plurality of grinding rollers 2 disposed at predetermined intervals around the center line and base members 1 continuously disposed in the circumferential direction around the center line for grinding the material between the plurality of rollers 2. In the grinder, the grinding rollers 2 are flat rollers with a smooth surface, and the base members 1 are grooved bases formed with slit grooves 6 in the crossing direction to the turning direction in the circumferential direction at predetermined pitches on an annular grinding surface grinding the material while biting it between the grinding rollers 2.
