The first step for efficient wood crushing is to choose the right type.
The first step for efficient wood crushing is which type of wood crusher to choose, the "tab type" or the "side-entry type". The first step for efficient wood crushing is to choose the right type of wood crusher.

You may be thinking, "I know that!" However, by reconfirming the features of the "tab type" and "side-mounted type", it may give you a hint to use your current self-propelled wood chipper more efficiently.

Please read on.

Tab type wood crusher

Tab type self-propelled wood crushers crush more and more wood by throwing the wood into the round dish-like tab from above.

It is possible to crush not only wood of a certain thickness, but also hardwoods with uneven trunks, their roots, or thick trunks close to the roots. (Depending on the size of the wood, it may be necessary to pre-treat the wood by breaking it into smaller pieces.

On the other hand, if you want to feed long pieces of wood, you need to cut them to about 2 meters in length beforehand.

In addition, since the wood in the tub comes into contact with the crusher by its own weight, if the weight becomes light, the crusher will spin out of control, and as a result, only about 80% of the crushed wood in the tub can be crushed.

In other words...
Tub type wood crusher is suitable for crushing a large amount of thick (large) wood and roots.

Horizontal Wood Crusher

In the side-loading type wood crusher, when the crushed wood is fed into the hopper conveyor, the holding roller grabs the wood and feeds it into the crusher.
Therefore, even if only one piece of wood needs to be crushed, it can be crushed without fail.

It is also possible to crush long pieces of waste lumber without cutting them.

However, there is a limit to the size (thickness) of wood that can be crushed because it cannot be larger than the height of the entrance to the crushing room.

In other words...
If you want to crush a small amount of wood, or if you want to crush long and narrow wood, a horizontal wood crusher is suitable for you.

Now, here's a question!
When crushing bamboo, which type of wood is more suitable for crushing, the "tab type" or the "horizontal insertion type"?

... ...

The answer is "horizontal insertion type".

As I mentioned earlier, the horizontal insertion type is more suitable for thin and long bamboo. If you cut the bamboo appropriately, you can throw in the tab method, but that is not the only reason why the horizontal insertion method is suitable.

Bamboo is characterized by its tendency to produce very stringy fibers. When crushing with the tab method, the bamboo fibers can accumulate in the gaps between the tabs and cause the hopper to fail.

Therefore, for the purpose of crushing bamboo, we recommend a wood crusher of the horizontal insertion type.

The mini chipper (SR3000-1) equipped with a cutting cutter blade and a shredder hammer is also effective for shredding a small amount of bamboo pruning branches, but it is a formidable enemy when it comes to shredding bamboo with roots. In such a case, it might be effective to introduce a strong two-shaft shredder such as FORUS HB180 or Big Bus VB450DK...

Now, let us introduce some of the innovations actually implemented by customers who use wood crushers.

To crush the grass...
The self-propelled wood crusher is a heavy machine for crushing wood into small pieces, but one of our customers decided to use it to crush a large amount of grass.

Although it is not officially recommended, the customer decided that it was possible to crush the grass with the wood crusher.

However, due to the high water content and fiber content of the grass, the grass got tangled and stopped, and the grass in the crevices burned due to friction.

Therefore, they researched how to crush the grass efficiently, and decided to "mix a certain amount of wood chips with the grass for the crushing process," which enabled them to crush the grass without any trouble.

In order to make the best size wood chips...
When wood chips are delivered to a biomass power plant, the power plant specifies the size of the wood chips. 

The screen is set up to take out wood chips of the specified size, but inevitably wood chips larger than the diameter of the hole slip through.

Therefore, in order to reduce the number of oversized chips and to efficiently produce chips with uniform particle size, they installed two screens with different hole sizes.

He experimented to find out what combination would give the highest accuracy and used the best combination to increase productivity. 

After all, this is a user who is faced with the actual site, the actual thing, and reality. Their spirit of research and ability to solve problems is mind-boggling.

Once? Twice? Make a cool decision for efficient use of wood crusher.

We all want to get the job of wood crushing done as easily and quickly as possible. In reality, we would like to complete the entire job with one piece of heavy machinery.

However, there are some people who dare to carry out the process in two steps.

First, a self-propelled biaxial crusher is used for primary processing (rough processing).
The biaxial crusher has two shafts that rotate at low speed and crush the material like a shredder, so it can crush even large pieces of metal with its powerful torque. However, since no screen can be attached to the crusher, it is not possible to adjust the particle size at once.

Therefore, a self-propelled wood crusher, either a tab type or a side-by-side type, is used for secondary treatment to adjust the particle size.

This is a costly process because it requires two pieces of heavy machinery, and it also requires two operations.

However, the load on the heavy machinery is greatly reduced, which reduces the risk of breakdowns and prolongs the life of the machine.
Of course, the frequency of replacement of consumables is also reduced. Also, the quality of the wood chips produced will be higher. 

Thus, when considering the efficiency of use and productivity of a wood chipper, it is important to consider the following

When considering the efficiency of use and productivity of a wood chipper, it is important to make a comprehensive and calm judgment, including the cost required at the time of purchase (initial cost).
