How to make a grain grinder from a washing machine with your own hands

A grain crusher will always come in handy, especially for those who keep livestock. Why waste time making food by hand when you can make a grain grinder out of a washing machine.

With this machine you can get corn and wheat flour, as well as process vegetables. So you will not only save money, but also give a second life to the old washing machine.

Grain Crusher Benefits

Why not buy a grain mill in the store? First, evaluate the benefits of homemade:

  • Useful application of old technology.
  • Minimal alteration of the washing machine, will cost almost free.
  • With the help of a homemade husk, you can process barley, rye, grain, legumes, husks. If you install a disc grater, you can get a chopper for vegetables, fruits and root crops.
  • The design is easy to manage.

The only drawback is that you need to pick up some details and spend your time.

How to make a grain grinder from a washing machine engine: instructions

For making a grain crusher with your own hands, the Soviet Oka washing machine or another model with a cylindrical tank is ideal.

Before making the device, consider the principle of its operation.

The design is simple and works on the technology of a coffee grinder, grinding the grain. Instead of an activator, knives or blades are installed in the washer, which allow you to process crops. A funnel is attached outside. Through its opening, the ground forage is poured into a container.

The whole grain will not fall into the container, since a fine mesh is installed in the structure.

Tools and accessories for assembly

The assembly of the structure is facilitated by the fact that it is not necessary to use a welding machine and a lathe. Tool you will need:

  • Bulgarian;
  • drill with drills;
  • passages;
  • chisel;
  • a hammer;
  • wrenches and socket wrenches;
  • nuts;
  • bolts;
  • emery;
  • secateurs.

Components:

  • metal fine-grained grating, preferably with sections of no more than 3 mm;
  • sleeve;
  • flange;
  • rubber and tin gasket;
  • steel plates (1,5×20 mm, thickness 1,5 mm).

Before embarking on the manufacture of a grain crusher yourself, study the detailed drawing of the device.

The dimensions of the device are individual. It all depends on the size of the washing machine.

The order of work

Sharpen the prepared steel plates with emery. To put them on the pulley, you need to make a special flange that will secure the knives.

Then proceed like this:

  • In the center of the knives, make holes with a diameter of 6 mm. Put them on the pulley.
  • Now you need to make protection so that the flour does not get into the mechanism.
  • From a piece of tin, make a patch with which you need to close the sleeve. The top is sealed with a rubber seal. For greater tightness, you can use a sealant.

Now you need to prepare a funnel for removing flour. It is connected to the drain – for this you need to expand the hole to 12-15 cm. Do this with a hammer and chisel.

In the prepared hole, install a branch pipe or a piece of pipe of the appropriate diameter. The feed outlet is ready. You need to install the grid.

How to install the grate

The grate should be in the tank at an angle of 15 degrees. At the same time, it should be in close contact with the walls of the tank. It’s quite easy to do this:

  1. Find out how high the knives will rise when rotated. Make a note.
  2. Step back from the mark up a few millimeters.
  3. Then prepare a grate that matches the size of the tank in diameter.
  4. Install the grate on the marked line, make sure that there are no gaps, otherwise the grain will slip.
  5. Secure the grate in place with bolts and nuts.
  6. If small gaps form during installation, cover them with cold welding and leave to dry.

To minimize the loss of grain during loading, make a hole in the lid into which to install the funnel.

Make a starting device from the washing machine engine. To do this, you need to properly connect the motor to the network.

How to connect the motor

4 wires come out of a conventional asynchronous motor – 2 of them lead to the starting winding, 2 to the working winding. To correctly identify the wires and connect them, use the electrical diagram.

You can also check the wires with a tester that is set to ohmmeter mode. For this:

  • Alternately apply the tester probe to each wire, looking for paired ones.
  • The wires leading to the working winding will show a lower value.
  • Connect work and start wire together.
  • Connect the remaining wires to a capacitor or a short pulse button.
  • Connect the power cord wire.
  • Start and check the engine.
  • To make the motor rotate in the opposite direction, swap the start winding motor.

How does a homemade grain crusher work

Run an empty structure, check the operation of the knives and the engine. If everything is in order, substitute a container under the output, fill in a bucket of grain and cover the device with a lid.

It turned out a reliable grain crusher for use in everyday life. Over time, you only have to sharpen the knives and use the device for your own pleasure.

Now you know how you can crush grain at home without buying expensive equipment. Old, unnecessary parts of the washing machine can always be adapted if desired.
