Many groups are seeing the cost benefits of in-field chipping, and are looking for even more capacity, and we have designed more mobile machines to meet that demand Michael Spreadbury, Peterson Corp Peterson’s secondary grate system provides ultra-consistent chip sizing; twigs and small stems which can be difficult to size are easily fractured through an innovative system. The Peterson 6910 disc chipper – mobility and high capacity in one package The Peterson 6910 disc chipper packs an 86 in (218 cm) 5-pocket chipper disc in mobile package that is ideal for many in-field chipping operations. The 6910 produces high quality paper chips when used with a Peterson 6800 debarker, or fuel chips as a stand-alone fuel wood chipper. The 6910 is powered by a Caterpillar C27, Tier III, 1050hp (772 kW), or a n optional C32, 1125hp (839 kW) engine. The 6910 has a five pocket disc, with several optional sheave sizes to make precisely the chip needed. The chipper disc is directly driven from a high-capacity PT-Tech hydraulic clutch and belts. Chipping production rates up to 200 US t/h (181,437 kg/h) can be achieved depending on chip size. The 6910’s large feed throat can accept up to 27 in (69 cm) diameter trees or multiple smaller stems. The 6910’s parallel wall feed throat stabilises logs. Direct drive feed rolls mean no chain and sprocket wear, nor is there ever need for adjustments. “Peterson knows that controlling the stems is critical for a high quality chip, and have minimised the distance from the feed roll to the disc for maximum control of the stems,” the supplier stated. “A primary and secondary anvil provides easily serviceable cutting surfaces for the highest quality chip.” The chipper housing features a quick release hood clamp, bolt in disc wear liners, and an oversized hood, which easily opens out of the way for superior disc access for knife changes. Servicing the 6910 is accessible from the convenient platforms around the engine and chipper. The 6910’s track system allows for easy machine alignment and site clean out, and the optional tow hitch allows operators to tow the Peterson 6800 Chain Flail Debarker to the job site for the ultimate in-field chip plant. The 6910’s large feed throat can accept up to 27 in (69 cm) diameter trees or multiple smaller stems A big bite for the best woodchippings The new Cobras from JENZ www.jenz.de Visit us at stand No. 329 JENZ GmbH Maschinen- und Fahrzeugbau Wegholmer Str. 14 ∙ 32469 Petershagen ∙ Germany +49 5704 / 94090 ∙ [email protected] ∙ www.jenz.de International Forest Industries | APRIL / MAY 2017 47
