Grinding type vertical grain milling machine

A grinding type vertical grain milling machine comprising:

• a main shaft that is perpendicularly and rotatably supported to a body base;
• a grinding type grain milling roll body that is formed in a cylindrical shape in the vertical direction by disposing a plurality of annular grinding type grain milling rolls in multiple stages;
• a cylindrical bran removing metallic mesh cylinder;
• a cylindrical bran removing cover;
• and
• a bran discharge pipe,
• wherein the grinding type grain milling roll body is attached to the main shaft so as to rotate together with the main shaft,
• the bran removing metallic mesh is disposed outside the grinding type grain milling roll body to be fixed to the body base and forms a grain milling chamber between the bran removing metallic mesh and the grinding type grain milling roll body,
• the bran removing cover is disposed outside the bran removing metallic mesh to be fixed to the body base and forms a bran removing chamber between the bran removing cover and the bran removing metallic mesh,
• the bran discharge pipe is disposed so as to communicate with the lower portion of the bran removing chamber,
• a motor rotationally driving the main shaft is disposed below the main shaft while being supported to a motor base,
• a fan-pulley is attached to the communication portion between the bran removing chamber and the bran discharge pipe in the main shaft, the fan-pulley having a function of rotationally driving the main shaft and a function of generating a bran removing wind for conveying bran produced by the grain milling action of the grinding type grain milling roll body from the bran removing chamber toward the bran discharge pipe,
• a conveying belt is wound between a motor pulley of the motor and the fan-pulley attached to the main shaft, and
• a moving device which adjusts a distance between the shafts of the motor pulley and the fan-pulley by moving the motor base relative to the body base portion in the horizontal direction is provided.
