During the LIGNA 2017, PALLMANN presents its newest Disc Chipper, Type PHS 36 in hall 26, booth E28. The size and the throughput rate of this disc chipper complete the Pallmann portfolio in the upper performance range of 100 - 120 t/h bone dry.
Disc chippers are especially suitable for the processing of straightly grown round wood into high quality wood chips. These chips are further processed where high quality wood chips are desired. This is especially the case in the wood-based materials industry for the production of MDF and HDF boards as well in the paper- and pulp industry.
The disc with horizontal bearing assembly has a diameter of 3.6oo mm and is equipped with 15 knives. As a standard, the chipper is equipped with a slanted horizontal feeding device. The new drive concept does away with the cost-intensive start-up hydraulic system. Machine start-up is now performed by a frequency-controlled pony motor. This motor also offers the possibility to reintroduce the energy produced during the braking process into the power supply in accordance with the dynamo principle. Chips are discharged straight down after size reduction. Due to the intake characteristics of the chipping disc, the logs are automatically drawn into the chipper without any additional draw-in rollers. This type of drawing cut results in a low specific energy consumption during size reduction. The material feeding system allows for feeding of logs up to 800 mm in diameter, respectively feeding of several logs at the same time.
Any parts subject to wear and which are in direct contact with the logs are made of wear-resistant material and are easily exchangeable.
Generously dimensioned knife changing flaps allow for easy access to the chipping chamber and quick and safe exchange of the knives.
