How to Make a Grinder From an Angle Grinder

To provide themselves with natural food, summer residents grow vegetables and fruits, keep animals. Crushed grain. The basis for the preparation of pet food. Grinder helps to grind grain. It is bought in a specialized trading institution, but you can do it yourself, using our tips and watching a useful.

How to Make a Grinder From an Angle Grinder

Preparatory work

In most cases, summer residents are fond of animal husbandry in order to have an additional source of income. For this reason, they decide to maintain a large number of livestock and poultry.

If the economy is small, and you don’t want to incur additional financial expenses, and crushing the grain is tiring, then you can build a homemade grain crusher from devices and materials that are available, but have not been used for their intended purpose for a long time.

The engine needs to be removed from household appliances, which are no longer used. It is only important that this engine meets the necessary technical specifications:

  • Had a power of at least 1 kW;
  • Worked from a power supply network of 220 V;
  • During operation made about 150 revolutions per minute.

Even if there is no engine with suitable parameters on the farm, you can buy it at a flea market. In any case, such a purchase will be more profitable than the purchase of a new grain mill.

Experienced craftsmen have taken multiple steps to create home-made crushers. In practice, it turned out that the most affordable and simple to implement were the options for home-made devices made from such devices:

It is recommended that you initially equip your workplace, prepare all consumables, analyze what tools will be needed to perform certain tasks. In most cases, it is required:

  • Hammer;
  • Chisel;
  • Hacksaw or metal knife;
  • Drill with a set of drills;
  • Staples, corners;
  • Various options for keys;
  • Bolts
  • Sandpaper.

It is useful to equip a homemade crusher with a funnel, which can be built if you prepare a piece of pipe in advance. The funnel is an element that allows you to send detailed grain to the prepared container.

In the presence of a fine-fraction grating, it will be possible to additionally sift the grain.

Grinder from angle grinder

If an old and no longer used angle grinder was discovered on the farm, you can give it a second life by building an excellent grinder out of it.

In order not to miss even the smallest detail, it is recommended to strictly follow the step-by-step instructions:

  1. Take a sheet of plywood or laminate, cut out a square or circle from it, which will serve as the basis for the future unit.
  2. Two holes are cut out in the prepared base (the first serves to feed grain from the hopper, and the second is cut out specifically for the saw).
  3. The hopper is a container in which the grain is initially filled. To create it, an old bucket or a five-liter plastic bottle will do.
  4. The saw is applied to the second hole and securely fixed (it is best to use prepared brackets and bolts).
  5. The previously installed disk angle grinder is removed, and instead, a knife made of durable metal is installed.
  6. Next, they fix an old colander under the knife (if there wasn’t one, you can build something like that yourself by drilling a sufficient number of holes in an already unused pan or metal basin).

This completes the manufacturing process of the crusher created from the old angle grinder. Now you can test the unit in practice and evaluate its functionality.

Vacuum Crusher

When conducting an audit in the household, you can find a vacuum cleaner that has been dusting itself unnecessarily for a long time. From it you can build a good version of the unit, which will perfectly grind the grain.

For the construction of a homemade crusher, not all the vacuum cleaner will be required, but only its engine.

The work must be performed in the following sequence:

  1. First, they create a foundation, taking as a basis a laminate or a sheet of plywood.
  2. The vacuum cleaner is disassembled by carefully removing its engine.
  3. A hole is drilled in the central part of the base, preparing a place for the motor shaft.
  4. The unit is equipped with a knife for grinding grain, which can be made independently from a metal plate.
  5. A knife is mounted and securely fixed to the motor shaft.
  6. A home-made unit must be equipped with a camera (a kind of sieve). You can make it from a colander or an old pan prepared in advance, at the bottom of which holes are pre-drilled.
  7. A hopper is installed and fixed under the sieve for receiving crushed grain (this can be a basin, a pan).
  8. It is recommended to attach a gutter to the working chamber, in the presence of which the grain loading process is simplified (you can create a gutter from a pipe or sheet of bent sheet).

Washing machine crusher

According to experienced craftsmen, a crusher made from an old, long-unused washing machine turns out to be as successful as possible. However, the process of its construction is accompanied by some difficulties.

The work is performed in the following sequence:

  1. First, the knives are selected, they are carefully honed with sandpaper (the quality and speed of grinding depends on the sharpness of the blade).
  2. The prepared knife is put on the shaft, which is fixed to the activator pulley of the washing machine.
  3. Next, go to the drain hole, it needs to be redone a little, expanding the diameter of the hole to 15 centimeters (detailed grain will subsequently pour out of this obtained hole).
  4. It is recommended to insert a funnel created from a piece of pipe, which will direct the precipitated grain into a container for its collection.
  5. A fine-grained grate is installed inside the tank so that it is in close contact with the walls and is necessarily at an angle of about 15 degrees.

General recommendations

When creating homemade knives that are installed in grain grinders, it is recommended to use only metal with a high level of strength. At a minimum, such a metal should not be inferior in its characteristics to St-3 steel.

In the process of continuous operation of the grain crusher, the knives will gradually become dull, and the quality of crushing will no longer satisfy. You can correct the situation by simply resharpening the knives. This procedure is not accompanied by difficulties.

However, some craftsmen can still make a mistake when creating the unit, fixing the knives “tightly”. Such an error will not allow you to remove the knives in order to sharpen them or replace them if they completely exhaust their resources.

For this reason, it is strongly recommended that the knives be fixed so that they are securely fixed, but they can still be removed if necessary.

Such a structural element as a sieve must also be removable. This will allow it to be removed periodically and subjected to thorough cleaning.

You should always remember safety precautions during the operation of a home-made unit. Leaving the working mechanism unattended is not allowed.
