KAMACHO's recycling technologies transform wasted lumber into valuable resources.

KAMACHO's recycling technologies enable our limited lumber resources to be reused.
Waste lumber is securely processed at high efficiency, and then crushed to transform it into reusable fuels and secondary products. It is a recycling system for the future that enables both the lumber recycling businesses and environmental conservation to be realized.

Lumber Recycling Systems

Renewed resources: Currently in the spotlight, wood biomass usage

Fossil fuels have been created over several hundred million years. Examples include coal that was made from plants from prehistoric times and petroleum made from the remains of plankton and seaweed that accumulated on the sea bed. Once consumed, these fuels can not be replenished in the rest of human history. Also notable is that CO₂ concentration in the atmosphere has risen. The most effective measure for preventing global warming is to stop using fossil fuels. On the other hand, biomass fuels are made from plants that are replenished in a relatively short period of time. The carbon contained in CO₂ circulates in the ground and atmosphere, without increasing the total amount of CO₂. In this regard, wood thinned from forests, wood building material waste and other waste lumber whose recycling is at issue can be used in large quantities as an alternative fuel for boilers and gas power generation if separated from foreign materials, crushed, and processed in other ways. For this reason, these materials have gathered much attention.

Twin Cutters (ESC Series)

Lumber is crushed powerfully with the unique twin cutter. Chips are made uniform through the screening method.

Various types of wasted lumber are crushed into chips for different ways of reuse.

Automatic reversal function saves labor

Even when the materials being crushed get clogged and the crusher stops due to an excessive load, the automatic reversal function clears the equipment to re-start crushing.

*Each motor is controlled independently.

Large hopper that can easily accommodate large-sized lumber

Twin cutter & screens

Economic advantages

Each blade is replaced separately and rotary blades that can be used on either side have been employed. The costs and labor for replacement and the amount of consumables, which are enormous for the conventional disc blade systems, can be significantly reduced.

*The fixed blades cannot be used on both sides.

Comparison of economic advantages when replacing rotary blades

Hammering Crusher (EHC Series)

Lumber is powerfully crushed using a high-speed hammer. The chip size can be adjusted by replacing the screen.

Initially crushed chips are granulated further.
