DIY repair of grain crushers

In detail: do-it-yourself repair of grain crushers from a real master for the site my.housecope.com.

An increasing number of people are moving to cottage settlements and private households. Often the owners organize micro-farms in their backyard, where poultry and animals are raised for their own consumption. The animals must be provided with high-quality feed, but it is impractical to purchase compound feed for a small livestock, therefore the owner is faced with the question of producing his own feed. Buying a grain crusher for several chickens or ducks is not economically viable. Such a mechanism can be made with your own hands from a grinder, which is available in every private house. The result is a small grain crusher capable of providing feed for a small farm.

To make a weaving crusher from a grinder, you will need the following tools and materials:

drill or screwdriver with a set of drills;
jigsaw or saw;
open-end wrenches;
hammer and chisel.
plywood 10 mm thick;
corner or staples;
bolts and nuts;
a saucepan of a suitable diameter;
knives;
Bulgarian.

Manufacturing begins with attaching an angle grinder to plywood using a bracket or corners. To do this, a rectangular hole is made in it for the LBM body and a round one for feeding grain. Fix the bracket with long bolts. The base can be made of various materials:

In the photo, the base is completed from laminate 8 mm thick. The staple can be made of any thin metal that can hold the clipper. M10 bolts were used for fastening. The knives are made of ordinary steel, 3 mm thick.

The sieve can be ready-made, for example old saucepan drilled bottom or any suitable container. The photo shows a fitted pan with a drilled bottom (holes with a diameter of 5 mm).

Then the angle grinder is fixed and the knives are screwed on. They can be with two or four blades.

It remains to fix the saucepan to the base, and the device from the grinder is ready. Install the receiving hopper of the grain mixture, which is made from a five-liter bottle... The result is a continuous grain crusher.

The entire structure is installed on a suitable container, connected to the network and the grain is poured into the receiving hopper. The grain mixture is fed into the working area, where grinding takes place.

The main disadvantage of this design is that the grinding size cannot be adjusted. The grain fraction is uneven. If a gate is installed on the receiving hopper, it will be possible to regulate the grain supply. This is done in order not to overload the machine's engine.

To obtain a finer grind, a different design is used. If in the first case the cutting mechanism is at the bottom, then in this version it located at the top... This design of the crusher is technically less complicated, since the base does not need to be made for manufacturing. The pan is attached directly to the grinder using corners. One hole was made in it for the grinder shaft.

When mounting on a shaft, it is necessary to install felt pad... It is forced onto the motor shaft and prevents dust from entering the mechanism. The entire device is fixed with a clamp to the table. The crusher is now ready for use.

The disadvantages of such a grain crusher include low productivity.... The advantages are as follows:

you can get a fine grind;
the structure can be used as a feed cutter;
beekeepers can make powdered sugar to make kandy.

A tight-fitting cover is required to reduce indoor dust.

In a subsidiary farm, it is often necessary to dispose of branch waste. To do this, you can simply burn them, but this is prohibited, as it can lead to fires. At enterprises, industrial shredders are used for disposal. But for small farmsteads, it makes no sense to purchase expensive shredders. Large volumes of branches and small trees are required for their work.

Using angle grinders, with a little modification, you can make a homemade shredder. With its help, it is easy to turn various plant waste into dust, and then use them. as mulch or as an additive in the preparation of compound feed.

For its manufacture is used Metal sheet 4-5 mm thick, in which two holes are made: one for the grinder shaft, the second for the supply of waste. Then a small piece of pipe is welded, the grinder and cutting knives are fixed. To ensure safety, the knives are covered standard casing... The shredder is ready, it remains to fix it vertically and get to work.

When making a device from an angle grinder, it should be borne in mind that it is not designed for continuous operation. After working for 4-5 minutes, let the electric motor cool down for 15 minutes. It is advisable to use a machine with a power of at least 1500 watts.

Following the link, you can see how to make a simple crusher with your own hands.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hair dryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

The grain crushers have a number of advantages:

Compactness allows you to move the device,
The device operates on a regular electrical network,
Large selection of models,
The ability to easily make at home,
The necessary spare parts for grain crushers can be found in every home.

A grain roller grinder grinds the product between two rollers that rotate in opposite directions. Rotary knives are distinguished by the fact that the knives are attached to the main rotary shaft. In hammer crushers, the main working unit includes the drum, sieve and decks. Crushing takes place under the influence of impacts in a hammer drum. In jaw crushers, the raw material for processing comes from the top and is crushed between two jaw plates. And in a cone device, crushing is carried out in a constantly rotating cone head.

One of the most popular models, which is used in many grain shops, as well as on farms and private backyards, is the Bumblebee grain crusher.

It is easy to use and affordable. The standard equipment includes such spare parts for grain crushers as lingums, grain suction devices, sieve with a mesh of 4 mm and a sieve with a mesh of 6 mm, as well as a power cable.

Bumblebee can produce up to two tons of crushed grain per hour, and the drum section is designed to produce more than 200 tons of grain between maintenance.

Homemade grain crusher is not inferior to its store counterparts. To assemble a grain crusher at home with your own hands, you need to stock up on working tools, as well as find the necessary spare parts for the grain crushers. Namely:

Cutting surfaces or knives: can be turned from steel, or you can use ready-made discs from a blender,
The engine for the grain crusher. The power must be at least 1.4 kW and not higher than 2 kW,
Crusher sieve: mesh size depends on grinding needs.

Before making a grain crusher with your own hands, you need to learn some important points:

Work knives should not be firmly attached to the device - they must be regularly removed and sharpened,
It is better to use very strong steel for the preparation of the knife,
Provide for the possibility of removing the sieve for cleaning,
Do not use the engine for a larger grain crusher - the power consumption will be higher.

The high performance of the apparatus depends on correct assembly as well as correct use.

The simplest model can be assembled from an ordinary household meat grinder. Making a grain crusher with your own hands from a meat grinder is simple: first, an electric motor is attached to it, and the neck is widened. For convenience, part of a plastic bottle can be glued to the neck. It turns out an analogue of an electric meat grinder. The productivity of such a crusher is a bucket of grain in twenty minutes.

At home, you can make a grain crusher from various parts from agricultural machines: from the brake drum of the tractor, the opener disc and the container from the seeder, as well as the metal plates of the cutting attachment of the grain harvester. To assemble a grain crusher, you need to use a convenient diagram or drawing for attaching all component parts. They can be found on the Internet in specialized forums.

A simple model of a crusher can also be made from a vacuum cleaner motor. To install the shaft, a hole is made at its base. The knife used should be about twenty centimeters wide and one and a half thick. The knife is attached directly to the shaft. Instead of the working chamber, you can use a regular metal sieve, under which a box or box for grain is placed.

Many households have discarded hand saws that are no longer needed. A grinder grain grinder can be a good saw attachment option. In addition to the saw itself, the following spare parts for the grain crushers are required:

A pipe section with a diameter of at least 15 cm,
Fine mesh or mesh,
Cutting discs (can be used from a meat grinder),
Grain box,
A sheet of plywood or laminate.

A do-it-yourself grain crusher from a grinder is done as follows: the body of the chainsaw is mounted on a plywood sheet, in which small holes are pre-cut for fastening. An additional slot is made on the sheet and under a box or can into which the crushed grain will be poured. Attach the chainsaw with metal brackets and bolts. A homemade crusher should be equipped with a sharp metal knife, sharpened on both sides. A mesh or sieve is attached to the bottom of a plywood sheet; you can also use homemade products from a pan. In this model, the grain crusher motor is the electric saw motor. The do-it-yourself grinder is ready!

A do-it-yourself grain grinder made from a washing machine is very popular among farmers.

The body of the washing machine is a ready-made powerful feed cutter. This type of grain crusher works on a principle similar to a coffee grinder: the grains are crushed in a drum due to the rotation of sharp knives in different directions. You can make this model with the following spare parts for grain crushers:

Cutting discs or knives
Lattice,
Additional engine,
Metal corner or narrow plates,
Hammer,
A small piece of metal pipe.

Before making a crusher from a washing machine, you need to sharpen the knives or used cutting discs well. The knives are pushed onto the shaft, and the shaft is then attached to the activator pulley with a washer.

The drain hole is increased in size with a hammer to a diameter of 12.5 cm. A piece of pipe is inserted into the resulting hole. On it, the crushed grain will be poured into a box or box. A grate with fine cells is installed in the tank of the machine at an angle of 13-17 degrees.Prerequisite: the size of the grate must be the same as the size of the internal tank.

Better grinding will help you get an extra motor for your grain crusher. Install it under the lid, and use a corner or metal plates for fastening. Another knife is placed on the motor shaft, the diameter of which is smaller than the size of the tank. It is advisable to cover the additional motor for the grain crusher with a cover. This will prevent dust and feed particles from entering.

To make a crusher you will need:

Electric motor with a power of about 1 kW.
Sheet metal 3 mm thick.
Hardened steel for a knife.
Bolts, nuts, washers, grovers - М8.
A metal drum or container of suitable dimensions.

Grinder with cut-off wheel.
Electric drill.
Grinding machine.
Welding machine.
Locksmith's tool.

The grain crusher consists of the following units:

A gate valve for regulating the supply of grain to the working chamber.
Grain bunker.
On-off button of the electric motor.
Electric motor.
Sleeve.
Axis.
Washer.
Screw.
Screw.
Base.
Working chamber body.
Capacity for crushed grain.
Bolt.
Screw.
Metal mesh (sieve).

Diagram of the crusher working chamber.

The grain crusher can be powered by a water pump motor of about 1.5 kW at 3000 rpm.

The engine is installed on a base, a metal sheet with a thickness of at least 3 mm. In the sheet, you need to drill a hole with a diameter slightly larger than the diameter of the motor shaft. We fasten the engine to the plate with bolts.

The working chamber can be made of sheet metal 3 mm, cut out a strip 40 mm thick and bend a ring with a diameter of 300 mm out of it. The ring is welded to the base.

To attach the knife to the motor shaft, you will need a clutch; you can order a clutch to grind off any turner.

The grain crusher blade can be made from a lawn mower blade or circular saw blade. The length of the knife should be respectively 10 - 20 mm less than the diameter of the working chamber. The knife is attached to the coupling with M 8 bolts, the coupling is put on the motor shaft.

We close the bottom of the working chamber with a sieve; the sieve can be made from a metal mesh with a hole size of 3 - 3.5 mm. We attach the sieve to the working chamber with pins and nuts, if you need to change the grinding size, it is enough to change the sieve to another one with holes of the required diameter.

Installation of a hopper for filling grain. Any cone-shaped container can be used under the bunker; for this, in the upper plate of the working chamber you need to make a small hole with a diameter of about 30 mm, weld the bunker onto it and make a valve to adjust the grain supply from the bunker to the chamber.

Place the grain crusher on a metal barrel or other suitable container.

We close the latch in the hopper and fill it with grain, turn on the electric motor and open the latch a little. Grain will begin to wake up little by little into the working chamber and grind with a rotating knife.

When the grain is crushed, it will begin to sleep into the lower openings of the working chamber sieve and fall into the barrel. Depending on the diameter of the sieve holes, you will get either coarse grinding or fine, until the grain is crushed to such an extent that it begins to fall into the holes, it will remain in the drum and be chopped with a knife.

A gate valve on the hopper is needed to regulate the grain supply, if the engine starts to lose speed, then it is necessary to reduce the grain supply by closing the valve, thereby reducing the size of the inlet.

The working knife wears out a little in the process, so it needs to be changed periodically.

When filling the grain into the hopper, it is necessary to ensure that stones and metal objects do not fall into the crusher together with the grain, which can damage the knife and damage the engine.

I recommend watching a video showing a homemade grain crusher at work.

Video grain crusher device.

please skip as on a bison 2 feed chopper remove the hammers from the shaft and install a grater

There is a lot of mind here, you just need a sheet of metal and cut and drill 3-4mm holes according to size as needed

On top of the box (where you put the grain) a grid, put it according to the size of the grain, it will catch garbage, crushed stone, nails, the idea is a penny, but it will help more than once, checked.

you don't need to cut it. combine overlap. it was stronger. but you can go to the reception of scrap metal. There you can find the devil. and made in the USSR. and now shit metal

my husband has a kamaz so there will be no problems

you can easily create one to take a filter from a KamAZ and cut out the desired size from it.

Yes, earlier fences at dachas were made of such iron, but now there is a deficit. But we have it in stores.

Buy yourself a 3 mm perforated stainless steel and you will be happy for 10 years, or even more.

Vladimir, how long was the home net enough?

Vladimir. I looked at your old vidos in which you raise this issue and, as a solution, voice the one proposed by me. It remains to wait for the snow to melt)))

Vladimir. What if you drill the required number of holes in a strip of metal? In my opinion, it will turn out faster and more reliable.

do you have to grind the grain? He threw whole rye into his own - they look with pleasure in the straw.

fodder chalk is sold in the same stores as compound feed. I give it as recommended on the package. fish oil in the same place, pour it on the eye for the smell, although there are also norms.

ahh, we hung up the lamp.for a long time already oborzeli)))) finally they found it at 150 watts, now at least it will not fry so well. otherwise, we have dimers standing up and all the same, these lamps are very hot. turkeys like to roast and chickens not so much. Where do you get chalk and how much do you give? And by the way, how do you knead fish oil too?

Vladimir is away, he is carrying out a government order. but about chalk and a shell, put them in a cup, they themselves will figure out whether they need additives or not. as you eat, add some sleep. it's also an abrasive for grinding food.

😉 vooooot and to someone all, who is more impudent, and to someone, what is left of more nimble brothers. because I also adhere to the fact that the grain mixture is much better. so the whole bird gets everything in the complex and will be healthier. I just wanted to ask the author of the video (sorry I forgot my name). ))) he adds chalk and a shell to the grain mixture or so gives. or maybe they don't need it at all with such a complex lunch

apparently a question to the owner of the channel. from myself, I add chalk to the mash almost constantly, the shell stands in a separate bowl in constant access while walking. in the summer there is enough sun for the absorption of calcium, in the winter I add fish oil to the mash. you can cut it off and hang the UV lamp))) and the grass will not be superfluous either in summer or in winter. like a sprouted grain.

The grain grinder is a versatile unit for grinding large and small grain crops that are included in the diet of cattle and other domestic animals. The grain crusher saves a lot of time and effort for its owner, and the processed feed can be mixed with various additives that improve the pet's diet.

Before considering the device of the unit, you should understand what a grain crusher is for. This machine is applied to crush forage crops, which makes them more attractive to pets. Small foods are much better absorbed by pets, which contributes to their rapid weight gain and the receipt of all the necessary minerals and vitamins.

The grain grinder has a relatively simple design. Its main elements include a robust body, which simultaneously serves as a receiving chamber, and cutting elements.

For greater convenience during transport, the grain chopper is equipped with handles, and more modern models are also equipped with removable wheels.

The design of any household crusher is distinguished by its simplicity and small dimensions. Nevertheless, each such model is characterized by a sufficiently high productivity, which makes it possible to process bulk consignments of material in a fairly short time.

According to the principle of operation, grain grinding machines are divided into several types. These include:

Hammer machine - in its design, grinding elements are mounted on a rotor that rotates inside the receiving hopper;
Impact crusher - working chambers of units of this type are made of durable metal, which guarantees high reliability of the machine. Grinding elements hit the walls of the hopper, thereby crushing the grain. In this case, the crushing elements will beat against the walls until the grain turns into the smallest fractions;
Disc machine - in a similar design, crushing knives are fixed on the shaft by means of special discs;
Roller crusher - it can both crush and grind grain. The main elements of this design are corrugated rollers. They only recycle wet material efficiently. Dry grain must be pre-moistened in water.

A hand crusher is the simplest device that requires the owner's time and effort to work with.This unit crushes the material into a coarse product, which can later be used to feed adult cattle;

Pneumatic crusher - this machine is used to process corn and other small products. Such a unit works quite quickly and crushes the grain into small fractions, which can be mixed into food for small pets, as well as for quails and other types of poultry;

Electric crusher - this machine features high performance and simple design. It does not have large dimensions, and is often bought, both for home and for farms.

Having studied in detail the types and differences of crushers, it will be much easier for a novice farmer to decide on the choice of a crusher for use in a home environment. Image - DIY repair of grain crushers

This question is asked by many novice farmers. To answer it, you will need to carefully understand the design differences between both types of units.

The work of a rotary shredder is to move the cutting knife. It is designed to crush the mass that is fed into the receiving hopper. The hammer unit crushes the raw material by means of hammers, which are attached to a solid base.

Products obtained with a hammer machine are considered to be of higher quality. This is achieved due to the high amplitude of movement of the hammers, which can grind even the most distant grains of grain. At the same time, the impact crusher consumes much less electricity and has a higher productivity.
