How To Make Double Wheel Flour Mill From Cardboard! DIY Machine at Home



Are you looking for a fun and educational DIY project? Here's a simple and creative way to make a functional double-wheel flour mill using cardboard! This project will not only give you a chance to explore your crafting skills but also demonstrate how basic mechanical systems work. Let’s dive into how you can make this flour mill at home with materials you already have!

Materials Needed:

  • Cardboard sheets (preferably thick and sturdy)
  • Scissors or a craft knife
  • Glue gun or strong adhesive
  • A pencil and ruler
  • Wooden sticks or dowels (for the axle)
  • Small wooden wheels (or you can make your own with cardboard)
  • A rubber band or small belts (optional)
  • A small motor (optional, for automatic operation)
  • Flour or wheat (for testing your mill)

Step-by-Step Guide:

1. Create the Base of the Flour Mill

Start by cutting a large piece of cardboard for the base. This should be at least 12 inches by 12 inches, but you can adjust the size depending on how large you want your flour mill to be. Make sure the cardboard is sturdy enough to hold the wheels and other components.

2. Build the Support Frame

Cut four pieces of cardboard that are 6-8 inches tall. These will form the vertical supports for your mill. Attach these supports to the corners of the base using glue. Ensure the frame is stable and straight.

3. Make the Flour Mill Wheels

Cut out two identical circles from the cardboard. These will be the grinding wheels. The size of the circles can vary, but a 4-6 inch diameter is ideal. Cut out a hole in the center of each wheel so they can fit onto the axle (wooden dowel). Use a pencil to mark the center and a craft knife to cut out the hole carefully.

4. Prepare the Axle

Take a wooden dowel or a small stick that fits through the holes in the wheels. This will serve as the axle. Make sure it’s long enough so that the wheels can spin without obstruction. Attach the wheels to the axle, ensuring they are spaced evenly.

5. Create the Grinding Chamber

Now, cut another piece of cardboard to create the grinding chamber. This should be a box-like structure that sits underneath the wheels to catch the flour. It should be wide enough to allow the wheels to move freely while grinding the flour.

6. Attach the Wheels to the Base

Insert the axle through the vertical supports of the base. Secure the axle in place with glue or tape, ensuring that the wheels can spin freely. You can use rubber bands or small belts to connect the wheels if you want to automate the mill by using a motor.

7. Testing and Adjustments

Place a small amount of wheat or flour into the grinding chamber. Rotate the wheels manually and see if the flour gets ground. If you used a motor, test it to ensure the wheels spin correctly. You may need to adjust the spacing between the wheels or the grinding chamber for better results.

8. Final Touches

Once your mill is working, you can decorate it with paint or other craft materials to make it look more like a real flour mill. Add small details like labels or handles to enhance the appearance and make it more functional.

How It Works:

The two wheels of the mill rotate against each other, grinding the grains into flour as they pass through the space between them. The friction and pressure from the wheels crush the grains into smaller particles, which fall into the chamber below.

Conclusion:

There you have it! A simple, yet effective DIY double-wheel flour mill made from cardboard. This project is a great way to explore basic mechanics and recycling materials. Not only will you have a fun time building it, but you’ll also get a working model of a flour mill that you can proudly display or use in your craft projects.

Happy crafting, and enjoy grinding your grains!
