Wood handling for energy

Chipping

Valmet has supplied more than 2000 heavy duty chippers to date, which is half of the entire number of disc chippers for the fiber processing industry worldwide. This has given us a valuable insight into chipper durability in tough conditions. Our wide experience has been utilized in the development of the chippers we have today. Valmet can offer, and have long experience of, both gravity feed and horizontal feed type of chippers.

Chip screening

A screening stage is often necessary to achieve the uniform chip size demanded in different processes. Valmet’s concept for chip screening includes several screening options, all designed for effective removal of oversize and fine fractions from the chip flow.

Bark handling

The bark from the debarking process can be transformed into useful energy in a mill's power plant. The energy value is dependent on the dry content of the bark.

Conveyor systems

Valmet offers a wide range of conveyors to efficiently transport chips and bark between the different process stages in the wood handling area and further on in the pulp mill, panelboard or power plant.
