PURPOSE: A grain grinding apparatus is provided to smoothly control a feeding speed of grains which are ground by a grain conveying groove which is formed on the inner circumferential surface of a drum which forms a fixed grinding plate. CONSTITUTION: A grain grinding apparatus(1000) comprises a fixed grinding plate(100) and a rotary grinding plate(200). The fixed grinding plate comprises a fixed plate base(110), a drum(120), and a fixed grinding protrusion(130). The drum protrudes in a ring shape from the fixed plate base. The fixed grinding protrusion is separated with a space from the drum, and formed by protruding from a fixed plate base. The rotary grinding plate includes grinding pins(220,230,240) which are formed by protruding with a fixed space from the rotary plate base and a rotary plate base. The grinding pins are arranged on multiple grinding concentric circles which have different diameters from one another. |
