Wood chippers (chippers) SRUB

Wood shredders

Increasing environmental requirements for production at logging and woodworking enterprises makes wood chipping equipment relevant and profitable. As a result of shredding wood waste, raw materials are obtained for the production of MDF, wood concrete boards, briquettes or pellets for heating private houses. Separately, the effectiveness of the use of shredders in logging plots should be highlighted, because heaps of branches, small size and other non-condition are disposed of on the spot.

offers a wide range of wood shredders, which are selected depending on:

Requirements for the quality of chips or shredded wood;
Composition of raw materials (waste) and their volumes;
Directions for further processing.

In practice, a technique is used to line up machines with different types of grinding into a line, which allows obtaining a product with high consumer properties.

Types of shredders

At the first stage of processing waste woodworking production, chippers are used. By type, these machines differ in:

Drum chippers suitable for processing waste wood and low-grade wood in the widest range of sizes.
Disco chippers with 3 ... 4 movable knives fixed on a disc with grooves. The cutting process takes place during the movement of the disk and the passage of a movable knife, fixed on the disk relative to a fixed counter-knife. The size of the chip fraction is regulated by the extension of the knife blade relative to the plane of the disc, which is the base.
Single-shaft and double-shaft wood shredders with circular knives have the highest performance. The shredder can process pallets, cable reels, etc., which may have nails, into chips. Chips are of poor quality and further processing requires magnetic separation to remove metal.

Deep processing of wood chips involves crushing to a size of 5 ... 12 mm. For this, a wood hammer crusher or a wood chip machine is used, which has a large number of knives or toothed discs. The feeding into the cutting zone is carried out from the hopper under its own weight or by means of a carriage with a drive.

A hammer crusher crushes wood chips using plates (hammers), which are fixed to the rotor and have a certain degree of freedom. Hammers fly over the sieve and crush the chips.

In some models of chippers, hammers crushing chips are installed on the rotor, in addition to chopping knives. A sieve is installed at the bottom of the machine, which calibrates the chips of the desired size. This arrangement reduces the size of the machine and allows you to get better quality raw materials.

Material production technology

Now you can consider the process of making chips. So, first you need to prepare the raw materials. The quality of this process depends on what kind of raw materials you need: peeled or barked, whole logs or waste. The wood chip crusher (chipper) now comes into play. The raw material is loaded through the hole into the hopper, where it is crushed.

Through special openings, the finished product enters the collection container or is sent along the conveyor to the drying chamber (if necessary). Next, the chips need to be sorted. Most often, vibrating screens are used for this, which have several platforms with cells of different diameters. Thus, you can quickly and easily separate large particles from small ones and improve the quality of your product.

Then the finished product can be packed and stored (or sent to the customer). It must be said that chips should be poured into special bins for short-term storage.

You also have the opportunity to simply fill up the product in special rooms, from where it will be shipped and delivered to customers. If you plan to expand your business, it is better to equip a special bunker gallery. It facilitates the process of loading the machines with chips. The fact is that a truck can drive right under the bunker.

In principle, these are all the features of the choice of equipment and the production of the presented material. Good luck!

Equipment for the wood chips production shop

Wood chipper Vecoplan VTH 2000 M NFT

Having decided on the direction of business, you can proceed to the next stage of organizing the workshop - the purchase of equipment. The main apparatus here is a chipper for the production of wood chips. It is she who turns the raw materials into the final product, which means that the quality of the manufactured products will depend on her.

You can buy a high-tech line that allows you to make different types of wood chips. But the cost is quite high - up to 3,000,000 rubles. But for entrepreneurs who are on a budget, it is better to assemble a line of separate devices - dryers, crushers, dyeing tanks and filling machines.

When equipping a workshop, it is worth choosing a wood shredder especially carefully. And the choice will depend on the planned production volumes and the available investments. There are several types of crushers on the equipment market:

single-disk,
drum,
hammer.

Each of the designated types of machines is good in its own way. Therefore, when buying, it is better to pay attention not to the grinding method, but to other parameters. So, a good chipper, what is it?

The thickness of the body in the part of the apparatus where the cutting elements are located must be at least 20 mm. Only in this case the chip crusher will serve for a long period without breakdowns and downtime.
Knives made of wear-resistant steel will grind the raw material better and faster.
It is good if the hydraulic feed consists of not one, but two pinch rollers.
Limit switches, which the machine will be equipped with, will protect workers from accidents.
Having the machine rotate 360˚ will make it easy to store the chips when they are thrown out of the crusher.
The machine will work longer if the number of knives is more than 2.

The following brands of budget crushers have proven themselves excellently - LASKI, BOXER. The price of cars does not exceed 200,000 rubles.

If we talk about the total cost of equipping the workshop, then the price of equipment for the production of chips of average capacity will not exceed 800,000 rubles. The line will include the entire set of machines and apparatus necessary for the production of a quality product. Of course, if we talk about more powerful machines, then their cost will be much higher - up to 2,000,000 rubles. But it is hardly advisable to equip the workshop with high-performance equipment until the distribution channels are well established.

And in order to further reduce the cost of equipping the workshop, you can think about purchasing supported equipment. The cost of used machines will be much lower, but here you need to pay even more attention to the choice of the technological line.

Purpose and advantages of wood chipping equipment

The problem with the disposal of substandard material exists at all logging and wood processing enterprises. Equipment for wood chipping allows solving the issue of freeing the territory from industrial waste and increasing profitability by earning additional profit from the sale of recycled products.

When working with any type of wood, waste is generated in the form of branches, slats, slabs and scraps of various shapes obtained during the manufacture of lumber. Garbage disposal is a costly and time-consuming procedure, alternative to which is a practical way of using crushing equipment. Machines grind substandard into chips or sawdust of the desired fraction, providing raw materials for sale or their own production:

chipboard, plywood, fiberboard, wood concrete;
fuel briquettes and pellets;
pulp, paper and cardboard products.

Small-fraction chips and sawdust in agriculture are used as bedding for livestock, for plant protection and soil fertilization. Shredded wood has good filtration capacity and provides high-quality biochemical water purification from insoluble compounds. Larger waste is required for the operation of boilers, pyrolysis furnaces and gas generators.

Production equipment

Before starting a business, you need to decide on the equipment. There is not much of it:

Chopping machine;
Apparatus for removing bark from a tree;
Drying chamber;
Wood cutting machine;
Sorting machine.

The main machine at the enterprise is a woodchip chipper. She is the heart of the workshop. They are of three types:

Disk. The simplest machines, the lowest in price and the weakest in terms of productivity. Ideal for starting a business with minimal investment. The principle of their operation is quite simple: from 2 to 4 knives work in the knife disc, which turn the initial product into chips. There are options with manual and hydraulic feed: the second is more expensive, but also much more convenient.
Drum. In comparison with the former, they can produce more product in the same time. Requires high power for normal operation. The wood is fed into a studded drum (manually or automatically), where it is subsequently processed.
Rotary. Heavy chippers, the most powerful class of machine tools. They can process pieces of wood up to 1 meter in diameter. Suitable for large enterprises with large production volumes.

Do-it-yourself equipment for the production of wood chips is purchased both at specialized sites and from hands.It should be borne in mind that despite the cheapness of used machines, problems with them are much more common and, in addition, they may require initial repairs.
