CHIPS QUALITY – HIGH ACCEPTS RATE

Demuth’s DPDI chipper is distinguished by its new and original constructive form, focused on a better chips quality and uniformity. Projected to allow a high rate of accepted chips, has consequently the lowest loss percentage (significat reduction of fines and oversized rates) when compared to other machines available in the market.

   

HIGH PERFORMANCE BRAKING SYSTEM

Disc-type brake, hydraulically activated, slows down the rotor speed and stop it in around 30 seconds, significantly decreasing the knife replacing time, apart of providing additional protection in emergency cases.

  

Rotor Acces

Protection hood with sliding or tilting removal, allows an easy access to the rotor for knives changing as well as for eventual maintenance services.

Bed Knife

The bed knife change, with a wedges fixation system, makes this operation extremely simple and quick. Through a hydraulic cylinder, the extraction of this bed knife can be effected in few minutes.

Log Kicker

Innovating system to remove logs that eventually can obstruct chipper’s infeed spout. These are quickly and effective liberated by the hydraulically driven Log Kicker, increasing the productivity at the chipping line, due to less stops.

Infeed Rolls

Auxiliary motorized rolls system for the logs infeed composed by toothed rolls, that avoid blocking or stopping of the logs between chipper’s infeed opening and the infeed belt.

Driving System

Through a gear box with one, two or four inlets, or by an pulley and belt set (in this case, driven by one or two motors).

DPDI Inclined Disc Chipper

A modern and simple design provides a high availability rate, easy operation and maintenance. Chipper idealized to process long and short logs, with high flexibility to be adjusted to different chip dimensions. The chipped material outlet can be downwards, by gravity or backwards, onto a flow equalizing bin and screw or a belt conveyor.

Sturdiness

Extremely robust, Demuth chippers are the heaviest in the market and can therefore support heavy working loads without affecting the chip’s quality and uniformity.

Monoblock Frame

With an inedited assembly conception, Demuth chipper becomes a monoblock unit mounted over an extremely reinforced frame. This project allows the distribution of the working load over a considerable bigger support area, giving stability to the whole set and allowing an adjustment between knives and counter-knives smaller than the usual, with a consequent gain in chips quality.

Front Bearing

Equipped with an exclusive patented system of high precision radial and axial bearings, guarantees total stability to the rotor during the chipping process, adding more uniformity to the chip’s length and thickness.
