Energy-eicient production o quality chips

Drum Chipper HRL

The MAIER Drum Chipper HRL is a high-perormance machine or the

production o high-quality chips or the PB-, MDF- and OSB-plants, as

well as or the biomass, pelletizing, WPC/WFC industry and many other

applications. As the core machine or the wood yard MAIER Drum Chip-

pers eectively process round wood, log ends, slabs and ocuts, veneer

residues or waste wood.

Free choice o wood assortment

Optimal chip quality

Chip length o 4180 mm

Energy-ecient size-reduction

Capacity o 5140 t bd./h

Individual turn-key solutions or

chipping lines incl. tailor-made

conveyor systems

Tried and trusted worldwide

Advanced and reliable technology

Broad application spectrum

Low-maintenance and service-riendly

High machine availability

Feeding o the material to the drum chipper

is eected by means o a eeding belt or a

vibration conveyor. The material is seized by

specially toothed ineed rollers and continu-

ously ed to the chipping rotor. The knives

o the rotor cut the material to the required

chip length. To avoid oversizes the chipped

material passes through an individually ad-

apted reractioning grid and is discharged

rom the machine by a screw, trough-chain

or belt conveyor.

Depending on the individual requirements,

the chippers can be equipped with variouseatures.

Innovations

Maxi-chips production with HRL-OSBThe Drum Chipper type HRL-OSB is designed or the production o chips with length up

to 180 mm. This chipper orms the irst process step o the 2-stage OSB system developed

and patented by MAIER. In the second step, these maxi chips are cut to strands or the

production o OSB by the MAIER Strand Flaker MSF.

Among others, maxi chips can be used directly e.g. or the production o charcoal.

Special machine design

Chip length up to 180 mm

Utilisation o raw materials previously considered to be unavailable or OSB production

Micro-chips production with HRL-M

The special Drum Chipper type HRL-M with modiied rotor design is used or the produc-

tion o very small micro-chips, e.g. or pelletizing and WPC/WFC industry, as well as or

smokehouses.

Special rotor design

Processing o variable wood assortments

Continuous production o micro-chips with length 4 mm possible

Tight particle size distribution

The Drum Chipper type HRL-B is specially

designed or the processing o variable input

materials, rom green waste up to round

wood, into chips or biomass power plants or

the pelletizing industry.

Tried and trusted technology based on the

high requirements o the panel board industry

Robust, reliable, eicient

Large inlet cross-section

Optimal material eeding with proven

ineed-roller system
