Wood crusher. What is a wood chipper? Types of wood crushers
Cleaning up trash on your property is often a rather problematic task. Plastic from the dacha or country house can be withdrawn when accumulated large quantity. Food waste can be easily disposed of in. But what to do with cut branches and unnecessary wooden structures, which in their shape and size are not suitable for such a pit?
1.1 Operating principle and design of shredders
The entire operating mechanism of the machine is built on the following main parts:
- support frame;
- power device;
- a shaft to which the cutting element is attached;
- shell for protection from fragments;
- special bunker for receiving raw materials.
Despite the simple structure of the device, it is quite heavy. Therefore, most modern machines are produced on a wheeled base to facilitate transportation of the shredder. The motor in the device is connected to the shaft via a belt or chain.
The operating principle of such a machine is similar to the operation of a conventional electric meat grinder. When you turn on the machine, the engine starts, which begins to push the shaft with the cutter. Wooden waste is placed in a receiving hopper and, as it passes inside, it is crushed into chips, which are thrown to the side or into a special hopper, which is installed on some models.

1.4 How to choose the right wood chipper?
When choosing crushing devices for wood, it is important to consider a number of features of such machines. They will allow you to choose a crusher specifically for the tasks, as well as significantly extend its service life.
The main criteria for purchasing are:
- Specific task of the device. When buying a shredder, it is important to know exactly what type of wood it processes and what kind of finished product it produces.
- Fuel used. It is important to immediately determine which fuel will be more economical and, based on this, choose an electrical device or gasoline / diesel models.
- Power of the power device. The engine used, despite the amount of work performed, is designed for a certain load. If the load exceeds the permissible load, the device will fail. This means that you need to accurately compare the expected work with the power of the model.
The price range of models may depend on functionality. For example, modern models with the ability to set the size of the finished wood chips will cost more than a simple garden structure. If even the most minimal equipment cannot be afforded, there is an option for do-it-yourself wood.
2 How to make a simple chopper yourself?
The design of such a device is quite simple, but without the presence necessary materials and experience on a bench and electrical equipment, it is better not to undertake its assembly on your own. All elements are made separately and then fastened together. You will need a powerful engine and materials for the body, connectors and cutting part.
When choosing an engine, you should take into account its power. For diameters up to 4 cm, a motor with a power of 3-4 kilowatts is suitable. A diameter of 4-15 cm can be processed in the presence of a more serious power unit of 6-7 kilowatts.
You can choose either a gasoline engine or an electric one. The first type will make the grinder more powerful, the second will allow you to work indoors.
As for the cutting element, the two-shaft system is most optimal here, in which the knives are placed on two shafts fixed between steel plates. This shaft is mounted using four bearings on the hopper body. Gears are welded to the far part of the shafts. They will transmit torque from the engine using belts. Next, we take cutting elements, they can be bought or cut from a KAMAZ spring. If the homemade shaft has a round shape, it is better not to install more than three knives.
After the blades are ready, they are sharpened at an angle of 35 degrees. Further, with the help of bolts, they are attached to specially made protrusions on the shaft housing.
When the knives are ready, you can move on to the chopping drum body. It is made from two flat sheets of steel. They should be rectangular in shape. Holes for bearings are cut in the blanks (two on each blank). The bearings are mounted on the shafts and welded to the workpieces. To increase the strength between the walls of the drum, it is better to fix a pair of spacers made of metal rods.
Next we make the frame. She needs a profile pipe, which is divided into 4 segments: two of them will be 80 cm long, and the other two will be 40 cm. These segments are interconnected in the form of a rectangle. Wheel stands are attached to the bottom surface.
The receiving compartment of the crusher is made of four metal plates, which are connected by welding in the form of a parallelepiped. The upper edge and the lower edge are turned away by 5 cm. The upper one is inside the structure, the lower one is out. Holes are drilled in the bottom sill for bolts that will connect the frame and the hopper. The upper threshold will prevent wood chips from flying out.
The first step in assembling the parts is installing the grinding drum. It is either welded or bolted. Next, the engine is installed and a belt is drawn to the gears of the shafts. The receiving hopper is installed last on the device.
It has a simple design, which simplifies repairs and has high performance characteristics.
Wood waste crushers are an indispensable tool for every organization or individual involved in any type of woodworking. Since this type of activity certainly leaves a lot of unused material, for example:
- branches;
- foliage;
- wane;
- bark;
- branch;
- slats;
- croaker;
- and other trimmings.
Wood waste crushers will help any enterprise or entrepreneur not only get rid of large amounts of waste, but will also allow you to obtain first-class material for the production of fiberboard or chipboard. The method of grinding wood residues brings not only economic benefits, but also enormous environmental benefits. Since the burning of wooden remains throughout the country, on such a scale, produces a huge amount of smog polluting the atmosphere. By using wood waste crushers at each enterprise, you can make a significant contribution to cleaning up the country’s ecology, and this method will also allow you to make your craft virtually waste-free.

The principle of operation of the wood waste crusher lies in its two shafts rotating towards each other, on which rotors with teeth are located, they also work as hooks for branches. You just need to point a branch or cutting a board towards the rotors, they will pick it up and instantly crush it into chips. Chips, in turn, through a special outlet sleeve, can be immediately loaded onto a car or any kind of bunker, since their supply can be directed in different directions and supplied to a height of up to 2.5 meters.
Such a mechanism is driven by electric motors with a power of 2 kW to 4 kW, if the supply voltage is 220 volts; if this unit is connected to a voltage of 380 volts, it may be equipped with more powerful drive motors. In this case, the specific power will be about 4-6 tons per hour.
Dimensions of loaded elements into wood waste crushers can be as follows:
- from 180 to 240 mm – width;
- from 140 to 220 mm – diameter;
- length is unlimited.
There are also hammer crushers wood waste, the principle of their operation is to cut off chips from damp or damp branches with impact force, the fiber part of which can clog rotary shredders.
Equipment such as wood chippers can operate in several ways, this does not affect the final result, the only difference is that each of them is optimally suited for certain types of trees or their condition. There are such principles of work:
- compression, under regulated pressure, resulting in crushing of the fibers;
- splitting into small parts;
- kinks in the rotor compartment, resulting in the branch breaking into small pieces;
- fixation of the supplied material, with a shift in different directions, which leads to grinding of the fibers into small parts;
- fracture, as a result of a powerful blow.
Depending on the technology, there are the following wood waste crushers:
- drums;
- disk;
- cheek;
- rod;
- conical;
- rotary;
- hammer;
- drums;
- roller
Benefits of using a wood chipper
Regardless of the principle of operation, wood waste crushers are designed to clear areas of wood waste from both production and everyday life. For example, every year municipal services, when cleaning parks and residential areas, collect tens of tons of similar waste, which is either burned or delivered to landfills for solid waste, which is an irrational use of such production materials.
The construction industry annually cuts down tens, or even hundreds of hectares of forest, only for the production of certain building materials, the main component of which is wood shavings. The use of a wood waste crusher will also make it possible to preserve natural green spaces. Which will also give positive result. Except for saving natural resources, this can also be called a contribution for the future to clean up and preserve the environmental situation in the country.

Crushers for wood and furniture waste are used for grinding various materials in order to reduce the size and obtain the desired fraction of chips, shavings, sawdust. In the future, recyclable materials can be used to solve various problems, for example, for pulp and paper mills, the production of biofuel, mulch, wood chips for smoking or other needs.
Equipment range
KAMI company offers you the following types of wood waste crushers:
In drum-type machines, slabs and other sawmill waste are fed into the crushing zone by feed rollers. Grinding occurs using a high-speed drum with knives. The resulting wood chips are sorted and further crushed using an output sieve. The main advantage here is the ability to obtain high-quality chips of the required fraction and integration into automatic sawmill lines.
In disk models, the grinding mechanism is a flat disk with knives. The main purpose of such crushers is to crush small wood waste after sawmilling, as well as to process branches after sanitary and other fellings for further disposal. The disadvantage of the equipment is the impossibility of obtaining homogeneous specified chips due to the lack of a sorting sieve. Disc crushers exist in stationary and mobile types - they operate from the tractor power take-off shaft. Main advantages mobile versions– the ability to install and operate in hard-to-reach places, as well as a relatively low price.
Stationary shredder crushers are designed for crushing furniture (chipboard, MDF), carpentry and plywood waste in order to obtain fuel chips or semi-finished products for the production of biofuels. The advantage of shredders is their ease of maintenance and reliability.
Hammer crushers are used when it is necessary to further grind dry material, for example, shavings from a 4-sided machine and then produce briquettes.
Specialized machines are used to produce shavings, for example, as bedding for livestock and poultry farming, or fine sawdust in one operation.

They have long been popular in our country, since forests cover most of its territory. Every owner of this type of enterprise must make every effort to increase its profitability.
This can be facilitated by a wood chipper. It helps to process a huge amount of substandard wood, which is usually thrown away, into a highly valuable and very high-quality product.
What is she doing?
The main purpose of this type of equipment is to process wood into chips. Recently, the demand for it has increased sharply, as the industry produces from wood chips OSB boards. They are very popular among buyers, as this material provides a real opportunity to build a cheap and high-quality house.
What types of wood waste crushers are there?
Each crusher can be mobile or stationary. Depending on the device, they are drum or rotary. But the techniques go even further, dividing them into other varieties:
- rotary tool with a vertical or horizontal shaft arrangement;
- hammer crushers;
- disk and cone models;
- screw and roller varieties;
- type.
Some features
Disc types of crushers work by using a rapidly rotating disc with a cutting edge to break the wood into chips. Discs can be flat or conical, and machines with the latter type are considered more powerful. This is especially true when their surface is profiled.
It is believed that the wood waste crusher with big amount knives on the working disk can process more raw materials in a shorter period of time.
The fact is that models with fewer knives work by chopping all the material within one cycle, while in varieties with several cutting surfaces at least one knife constantly comes into contact with the wood.
Raw material supply methods
The feed mechanism can be vertical or horizontal. A wood waste crusher that can use an additional conveyor to feed it will cost more. In general, feeding methods are divided into manual and forced. But much better and safer are those varieties that have a vacuum or gravity feed.
Nutrition
A stationary wood waste crusher, which can be rented in almost any major city at a negotiable price, is in most cases equipped with an electric motor.
Such machines are equipped with hydraulic feed systems. Most often they are used in urban environments, when cutting branches are processed.
Mobile varieties are equipped with powerful diesel engines, and sometimes are simply built on the basis of wheeled ones. The process of their operation is greatly facilitated by the fact that the material is fed into the drum automatically, no human intervention is required.
What's the price? A wood waste crusher costs about 260 thousand rubles or more.
