PTH 1400/820 G
PTH 1400/820 G Industrial drum chipper, for those operators looking for high productivity, reliability and quality.
The chippers 1400/820 G are robust and powerful machines which stand out for the width and the diameter of the drum and the material feeding opening.
These chippers are capable of processing large quantities of any type of woody biomass in a short time, producing up to 200 cubic meters per hour of high quality and homogenous size wood chips, which can be then destined for large power stations, gasifiers or small boilers.
The diameter of the chipper drum (820 mm) and the width of the feeding opening (1400 mm) allow the machine to process logs with a diameter up to 600 mm.
The robust hydraulic fan, which is standard on this machine family, allows the dynamic adjustment of the rotations. With dry material it is possible to work at low speeds, reducing either the consumption and the dust generated during processing. With wet material, such as that produced by green maintenance operations, the revolutions can be increased, keeping the evacuation of wood chips smooth and avoiding obstructions.
These chippers are designed with a conical-shaped feeding opening, a feature that, combined with the upper roller that opens completely, allows even very bulky logs and branches to be processed effectively, thus increasing productivity.
The closed feeding chain brings the material to be chipped to the counter-knife, a design feature that eliminates the problem of ‘wasted material’ accumulating under the machine after each movement, thus avoiding the need to slow down the equipment for site cleaning. The recovery augers, positioned under the final part of the feeding chain, collect any excess of chipped material and convey it for expulsion through the exhaust fan.
The cutting system used by Pezzolato consists of a closed drum with staggered sections equipped with knives, a counter-knife, and an interchangeable calibration grid. This system guarantees the production of quality wood chips, as the closed drum allows the cutting length of the wood chips to be kept fixed and constant. The wood, subjected to the action of the knife, is transformed into calibrated chips, which are able to pass through the calibration grid immediately after cutting.
Worth mentioning is the system with the collapsible counter-knife: this system minimizes any damage caused by the accidental introduction of foreign bodies (not biomass) into the chipper.
