Compound feed is eaten by many species of farm animals, the purchase of feed is not cheap. In this regard, many farmers prefer to prepare the mixture on their own, and in order for the savings to be complete, they prefer homemade units for purchasing factory machines. How to make a granulator, understand in this article.
The principle of operation and the device granulator
For small private farms, an aggregate produced from a conventional, slightly modified meat grinder will suffice. The device is a homemade machine based on a belt drive engine. With the help of the auger, the raw material placed inside will be pressed through in the form of long thin sausages through the holes in the matrix. At the exit they, with the help of installed knives, are cut in the right size.
Did you know? The first plant for the production of combined feed for farm animals and birds was commissioned in Moscow in 1928.

Even the simplest product is not made without preliminary calculations and sketches.
Design and Drawings
To create a drawing on the basis of a meat grinder, it is necessary to remove all necessary dimensions, the grid parameters are especially important, since the matrix of the product must correspond to them.

After the outline of the drawing, care should be taken to ensure that you have at hand all the tools and accessories that may be needed in the work.

Materials and tools
For the manufacture will need the following parts and tools:
- crafting table;
- lathe;
- rubber mat (for safety);
- meat grinder with all the details;
- drilling machine;
- pulleys 1: 2;
- stainless steel blank or steel;
- belt;
- welding;
- 220 volt electric motor.
Manufacturing steps
The first thing that needs to be done is to prepare the basis of the structure: if we consider that the matrix will abut the worm gear, its edges may need to be removed. For convenience of work, the device is fixed on a workbench, drilling holes for bolts in the legs.
Matrix
For the manufacture of the matrix will need a stencil, you can make it in any graphic editor. The blank under the matrix is taken from stainless steel: it is strong and durable. On the surface impose a paper stencil and on the machine make the required hole size.
We advise you to read about how to make feed for ducks, turkeys and chickens with their own hands.Note, the diameter of the holes depends on the thickness of the blanks:
- diameter for 20 mm parts will be 3 mm;
- matrix 25 mm thick - diameter 4 mm;
- thickness 40 mm - diameter 6 mm.

Cap
The lid holding the grid in the meat grinder is no good; a new lid should be turned under the matrix. For the manufacture of threads on the lid, there are two ways: weld the wire, cut into a grinder. If it is easier for you to work with wire, calculate the required material diameter.
Important! It is desirable to make a cover with a stock, but not end-to-end. Perhaps, then you have to make a larger matrix.
Pellet Knife
In the meat grinder auger, they drill a hole for a knife holder, and the knife is attached with a bolt on the outside of the die.
Pulley installation
The pulleys are mounted symmetrically, you need to fasten very carefully, because they will transmit the movement of the drive belt. In place of the handle fasten the driven pulley, on the motor shaft - the leading pulley. 
Belt tension and engine installation calculation
The pulleys are connected to the engine with a belt drive, taking into account possible slippage.
Important! The wheel on which the belt will be tensioned should not be toothed: this will increase the risk of engine failure due to overheating.
Adjustment and improvement of the mechanism
After the mechanism is assembled, for convenience of work with it, a hole in the former meat grinder is welded to the container in the form of a funnel into which the raw materials will be laid. The finished design start, tracking the work of all parts, the belt tension.
Note possible shortcomings for further refinement. How the simplest mechanism from the old meat grinder works can be viewed in this video: Factory machines are usually expensive, not all farmers can afford it. If there are small skills in mechanics, and the hands are not afraid of work, then you can significantly save money on the production of independent improvised units.
Did you know? Poultry farming is considered the most consumed industry in the field of animal feed. Of the total amount of feed produced in the world, poultry farming accounts for 60% of production.
