Woody biomass

Depending on the material, the logistics and the customer requirements, single machines or machine combinations from our shredding and screening technology are in use. 


Using the chipper configuration, the Axtor produces a quality chipped material in a defined grain size from logs. A fuel with a coarser structure can be generated from woody green waste, clean forest residues or untreated waste wood by working in shredder or chipper mode depending on the input material.

When producing biofuel from green waste, the Crambo, the tough all-purpose shredder, is ideal for this, as its large screen basket sizes give the right particle size for further processing.

A fine fraction, a medium fraction and a coarse fraction can be produced in one pass with star screens. The medium fraction is generally the usable fuel fraction. Products_Multistar_L3_2-Achs_Trailer_Rendering_Card.png

Shredding with
high speed

A fuel with a coarse structure can be generated from woody green waste, clean waste wood and forest wood residue by shredding with the general-purpose Axtor wood-shredder. Simply exchanging the free swinging tools for fixed tools converts the Axtor into a powerful chipping machine for logs. 

Coarse shredding
with low speed

“As coarse as possible – as fine as necessary” – that´s the secret of efficient processing. The right application for the robust universal wood shredder Crambo, producing the proper particle size for further processing with screen baskets of 250 mm or even larger. The low-speed gives a high level of insensitivity to contraries. 

Screening with
star screen

A fine fraction, a medium fraction and a coarse fraction are produced in one screen operation. The medium fraction generally represents the usable fuel sample. The fines are processed to compost and the coarse particles are brought back to shredding. 

Cleaning of
end product

If required plastic is separated by a Hurrikan windsifter, metals are removed by Fe-separation and stones are eliminated by a Stonefex stone separator. The new Hurrifex does both tasks in one step.
