PURPOSE: A grain mill is provided to prevent the generation of metallic dust particles during the operation of milling by preventing grain from contacting with a metallic material. CONSTITUTION: The grain mill is comprised of: a frame(20) installed over a mortar body, to which a driving shaft(24) coupled with a driving pulley is rotatably installed; a semicircular driving cam(30) rotatably installed to the frame so that it is eccentric with a cam shaft(31) coupled to the driving shaft; and a mortar stick(40) reciprocating upwardly and downwardly according to the rotation of the driving cam. The upper end of the mortar stick is rotatably coupled to a driving roll(41) and the lower end is coupled with a wood mortar(42).
