How Does a Corn Grinder Grind Corn?

A corn grinder is an electric device used to process dried corn into coarse powder, fine flour, or corn grits. It grinds corn kernels into powders of various fineness through the high-speed rotation of grinding plates. This machine is widely used in households, farms, and food processing plants.

So, how is corn grinding done?

What is the working principle of a corn mill grinder?

• The motor drives the grinding plates to rotate at high speed, generating strong cutting force.
• Dried corn kernels enter from the feed inlet.
• The corn is repeatedly ground and crushed between the grinding plates.
• The crushed material is discharged through a screen, and the mesh size of the screen determines the final fineness.
• Finally, the ground corn powder or grits comes out from the outlet, completing the grinding process.

Corn grinding operation steps

1. Raw material preparation – Select dry and impurity-free corn kernels; remove stones, metal, and other hard objects; keep moisture around 13%.
2. Pre-start check – Ensure the power is properly connected; open the outlet and attach a collection bag.
3. Start the machine – Let the motor run idle for a few seconds to confirm normal operation.
4. Slow feeding – Pour corn kernels slowly and evenly into the feeding inlet.
5. Collect final product – Ground corn flour or grits will be discharged automatically; replace screen mesh as needed to adjust fineness.
