Grinding machine and grinding method for producing organic coarse cereal superfine powder

The invention discloses a grinding machine for production of organic coarse cereal superfine powder, the grinding machine comprises a shell, the inner wall of the shell is fixedly connected with a first grinding seat, the top of the shell is fixedly connected with a first motor, and the output end of the first motor extends into the shell and is fixedly connected with a grinding block. The proximity switch is arranged to detect the number of organic coarse cereals in the shell, when the organic coarse cereals are too many, a signal lamp is started to remind a worker, vibration generated when the grinding machine works is absorbed through the shock absorber and the wear-resisting bottom plate, and therefore shock absorption and noise reduction are conducted on the grinding machine; organic coarse cereals are ground through the first motor, the grinding block, the first grinding base, the second motor, the grinding roller and the second grinding base, different kinds of organic coarse cereals are ground into or
