Roller motor

This type of motor is designed to operate the various sets of rollers used to convey material both before and after processing.

Bark remover

A series of peeling blades removes the bark (and other impurities) from the cut tree trunk.

Cutting to length

This reduces handling costs and produces logs of a standard length.

Sawing

The log receives its first lateral cuts in this process to provide a basis for the machines operating downstream. It trims off excess from the sides and cuts the timber to width, depending on requirements and the quality of the wood.

Planing

The definitive length and width of the wood are established at this stage, and impurities are removed.

Stacking

The wood is classified by size and quality, according to requirements.

Bark remover

These machines are used to clean and debark timber.

Cleaning and preparation for chipping

Bark and other impurities are removed at this stage to leave the timber ready for chipping.

Chipping

Once the bark has been removed, various conveying systems transport the logs to the large chipping machines for rapid conversion into wood chips.

Conveyor belt

This system, which consists of a continuous belt designed to move over a series of rollers, is used mainly in agriculture and industry to transport granular materials and other items.

Cutting mills

The previously cleaned wood chips run through the cutting mills, which are precisely calibrated to produce finished chips of exactly the right size needed to make chipboard.

Silos

The finished wood chips are reclassified and separated from the sawdust before being sent to corresponding storage silos.

Endless-screw mechanism

Endless-screw mechanisms use a two-piece arrangement of a pinion and crown wheel to transmit movement between axles that are perpendicular to each other. They provide a compact way of reducing speed and increasing torque, particularly on small electric motors – which generally operate at high speed and low torque.

Driers (hot-air burners)

The burner provides heat at the temperature needed for drying.

Fans (cold-air type)

The finished chips are dried by passing them under large fans designed to generate a strong current of air.

Conveyor belt

This system, which consists of a continuous belt designed to move over a series of rollers, is used mainly in agriculture and industry to transport granular materials and other items.

Drum rotation

The drum rotation mechanism requires variable-speed drives to control its r.p.m. and guarantee the reliability of the process.

Conveyor belt

This system, which consists of a continuous belt designed to move over a series of rollers, is used mainly in agriculture and industry to transport granular materials and other items.

Pressing and drying

Pressure is progressively applied to the flat surface of the board during this process, until the desired caliber is achieved. The pressing rate depends on the caliber specified (the greater the caliber, the lower the speed).
The boards leave the press to be cut and then placed on rotating elements designed to let the boards cool down for stacking and packing
