Drum Chipper HeliCoil thread technology

Usual construction style:Uneven weight and

tension distribution

HeliCoil-technology:Even weight and

tension distribution


23/28

Drum Chipper Universal machine-shoes

Usual construction style:

Fast and precise adjusting shorten mounting;

thereby max. stability throughtangential power. Vibration will be caught and therefore nottransmitted into foundation.

Isolec technique:

stretched spindle due tothermic tensionsas a result of welding

no counter bearingof the spindle end.Spindle will be squeezed outof middle axes


24/28

Drum Chipper Your advantages Chipping-width bigger than infeed width

Regrinding traverse suited at the end of the screen

Screening area compared to infeed diameter extremely enlarged

Rotor shape adjusted to the chipping length

Changeable wear plate beneath the chipping knives

High quality chips due to optimal chipping geometry and improved material infeed

Chipping of all kinds of wood

Chips production after strict claims


25/28

Drum Chipper Your advantages

Knife clamping electively with hydraulic operating wedge or mechanical clamping plate

Feeding of the drum chipperpossible with feeding belt, vibrating trough or steel plate belts

Transport of chips through screw conveyor, conveyer belt, chain conveyor or pneumatic

Motor console integrated in machine case

Flat belt drive

Low noise generation

Spread worldwide and proved since decades for ful l satisfaction of our c lients


26/28

Drum Chipper Your advantages Low wear out of the feeding rolls

Easy changeable wear parts

Even, one-parted main shaft for fasten the rotor with tension elements

Continuous and economical working procedure

Lateral sealing of the front feeding roll carriers for dust protection

Low maintenance costs

Trouble free infeed and secure locking of the material by two individual feeding rollscarriers

Easy changeable chipping- and counter knife


27/28

Drum Chipper Your advantages Manual or electro-hydraulic counter knife discharge

Counter knife with two edges and regrindable

Screen out ofmassive rol led steal plates

No personal required during operation

HeliCoil technology for optimal gripping power of screws; threads are replaceable

Installation of the drum chipper on vibration cushioning elements
