PROBLEM TO BE SOLVED: To provide a method for producing flour and a pulverizer for producing flour, which can suppress wear and improve the quality of flour. A first crushing member (10) having a crushing surface (11) and a crushing surface (11) of the first crushing member (10) are opposed to each other and relatively rotate coaxially to each other, whereby the first crushing member (10) is rotated. A crushing machine for flour production, comprising a second crushing member 20 having a crushing surface 21 for crushing grain between the crushing surface 11 and the crushing surface 11, and a crushing surface 11 of the first crushing member 10 and a second crushing member. One or both of the crushing surfaces 21 of 20 rotate, and the crushing surfaces 11 and 21 of the first crushing member 10 and the second crushing member 20 have uneven surfaces formed by spraying a tungsten carbide cermet. A crusher for flour production, wherein certain surface layers 14, 24 are formed. [Selection diagram] Figure 1【課題】摩耗を抑制するとともに、穀粉の品質向上を図ることができる穀粉の製造方法および穀粉製造用粉砕機を提供する。【解決手段】粉砕面１１を有する第１の粉砕部材１０と、第１の粉砕部材１０の粉砕面１１と対向し、かつ同軸上で相対的に回転運動することで第１の粉砕部材１０の粉砕面１１との間で穀物を粉砕する粉砕面２１を有する第２の粉砕部材２０と、を備えた穀粉製造用粉砕機において、第１の粉砕部材１０の粉砕面１１と第２の粉砕部材２０の粉砕面２１は、その一方ないし両方が回転するものであり、第１の粉砕部材１０および第２の粉砕部材２０の各粉砕面１１，２１に、タングステンカーバイドサーメットを溶射してなる凹凸のある表面層１４，２４が形成されていることを特徴とする穀粉製造用粉砕機。【選択図】図１
