The objective of the milling process is to provide complete separation of component parts of the steeped corn kernels. After steeping, the grains are coarsely ground of pulp with water in coarse grinding attrition mill in preparation for de-germination. Grinder has one stationary and one rotating disc. The gap between the plates can be adjusted to give the most germs free with minimum breakage with quick release spring mechanism for easy retraction attached with rotational shaft to prevent accidental damage to grinding plate due to any metallic foreign particles.
