Multiple major manufacturers of horizontal grinders have released new models in 2018. HOGS, as they are sometimes called (HOrizontal GrinderS), are unquestionably the workhorse of the wood recycling industry and are a key piece of equipment for composters, land clearing contractors and biomass-for-energy producers, as well as C&D and MSW processors, where in both cases, wood and other organics are part of a mixed stream of materials. The latest model horizontal grinders feature lighter weights with higher production, increased transportability and site mobility, diesel, hybrid and fully electric power options, along with sophisticated controls systems, and ease of use and maintenance for operators and owners. This article looks at the latest horizontal grinder models and updates from Morbark, CW Mill, Rotochopper, CBI, Diamond Z, Bandit, Vermeer, Precision Husky, and Peterson Pacific.
Precision Husky’s new 4042 Drum Chipper is powered by a Cummins 600-hp or Cat C15 engine. These units are designed “without a bunch of bells and whistles,” are very economical to operate, produce more than 75 tons per hour, and are ideal for biomass production operations.
Precision Husky recently shipped their largest Whole Tree Chipper, powered by a 1,050-horsepower diesel engine, along with two diesel-powered Horizontal Grinders to customers in Scandinavia.
“A few years ago you could measure our international business with a fraction of one percent,” stated Bob Smith, chairman and CEO of the corporation. “Today, Precision enjoys approximately 50 percent of its total volume from international sales.” He added that “the international market seems to be coming out of recession faster than the domestic market.”
ProGrind H-3060 horizontal grinders include a Caterpillar C-15, 565 hp diesel engine, and a large-diameter infeed roll that is sensitive enough to permit grass clippings, brush, limbs, pallets, slabs, logs and stumps to be fed at variable speeds for continuous rather than batch feeding This grinder is engineered with several cutting surfaces at varying depths, which virtually eliminates the frequent jamming characteristic of more conventional type grinders. The large diameter feed wheel allows easy access to the hammermill and the changeable screens, and the wheel has free-fall restrictors. When raised, the wheel is parked against dual safety stops with a hydraulically operated safety pin. The H-3060 is available on tracks or trailer mounts.
