 **Working Principle**

1. **Feeding**: Maize kernels are fed into the hopper.

2. **Grinding**: The grinding mechanism crushes or grinds the kernels into the desired consistency.

3. **Separation**: Some mills include sieves to separate flour, grits, and husks for different uses.

4. **Collection**: The processed maize is collected in a container or bag for further use.

 **Types of Maize Grinding Mills**

1. **Hammer Mill**: Uses rotating hammers to crush maize into flour or grits. Ideal for coarse grinding and high-capacity output.

2. **Stone Mill**: Employs grinding stones for a finer texture. Often used in traditional or artisanal settings.

3. **Roller Mill**: Utilizes cylindrical rollers to crush and grind maize. Ensures uniform particle size and is commonly used in large-scale milling.

4. **Posho Mill**: A compact mill popular in rural areas, often powered by diesel engines.

5. **Multifunctional Mill**: Designed to handle various grains and achieve different outputs like flour, grits, or bran.
