A grain crusher is always useful, especially for those who keep livestock. Why waste time making feed manually if you can make a grain mill from a washing machine.
With this machine you can get corn and wheat flour, as well as process vegetables. So you 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 use of old technology.
- Minimum alteration of the washing machine will cost almost free.
- With the help of homemade grits, you can process barley, rye, grain, legumes, husks. If you install a disk 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 mill from the washing machine engine: instructions
For the manufacture of grain grinders with their own hands, the Soviet Oka washing machine or another model with a cylindrical tank is ideal.
Before making a device, consider the principle of its operation.
The design is simple and works according to the coffee grinder technology, 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 to the outside. Through its hole, ground fodder is poured into a container.
Whole grain will not fall into the tank, since a fine mesh is installed in the structure.
Assembly tools and components
The assembly of the structure is facilitated by the fact that it is not necessary to use a welding machine and a lathe. The tool you need:
- Bulgarian;
- drill with drills;
- pliers;
- chisel;
- a hammer;
- wrenches and socket wrenches;
- nuts
- bolts
- emery;
- secateurs.
Accessories:
- a fine metal grate, preferably with sections of not more than 3 mm;
- sleeve;
- flange;
- rubber and tin gasket;
- steel plates (1.5x20 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.
Work order
Sharpen prepared steel plates with emery. To put them on a pulley, you need to make a special flange that will fix the knives.
Then proceed as follows:
- In the center of the knives, make holes of 6 mm diameter. Put them on the pulley.
- Now you need to make protection so that the flour does not fall into the mechanism.
- From a piece of tin, make a patch, which you need to close the sleeve. The top is closed with a rubber gasket.For greater tightness, you can use a sealant.
Now you need to prepare a funnel for the withdrawal of 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 a chisel.
In the prepared hole, install a pipe or piece of pipe of the corresponding diameter. Retraction for forage is ready. Need to do the installation of the grille.
How to install the grille
The grill 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. This is not easy to do:
- Find out what height the knives will rise during rotation. Make a note.
- Step back a few millimeters from the mark.
- Then prepare a grate that matches the diameter of the tank.
- Set the grate on the marked line, make sure that there are no gaps, otherwise the grain will skip.
- Secure the grate in place with bolts and nuts.
- If small cracks form during installation, coat them with cold welding and leave to dry.
To minimize grain loss during loading, make a hole in the lid into the funnel.
Make a starter from the engine of the washing machine. To do this, you need to correctly connect the motor to the network.
How to connect the engine
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 wiring diagram.
You can also check the wires with a tester that is set to ohmmeter mode. For this:
- Alternately apply a tester probe to each wire, looking for paired.
- The wires leading to the working winding will show a lower value.
- Connect the working and starting wires together.
- Connect the remaining wires to the capacitor or short pulse button.
- Connect the power cord wire.
- Start and check the engine.
- To make the motor rotate in the opposite direction, swap the starter motor.
How does a homemade grain mill
Run the empty structure, check the operation of the knives and 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 your knives and use the device for your pleasure.
Now you know how to crush grain at home without buying expensive equipment. Old, unnecessary parts of the washing machine can always be adapted if you wish.
