Like all Kadant Carmanah chippers, the 96-inch Whole Log Chipper is designed to produce high quality chips with a focus on machine longevity and simplified maintenance. The shear pin protected anvil reduces operational costs by limiting damage caused by tramp metal and rock hits. The heavy-duty base is constructed from thick steel sections to minimize flexing under heavy load and permit close knife-to-anvil clearances. Kadant Carmanah’s 96-inch Whole Log Chipper can easily be adapted to produce either standard pulp chips or micro-chips as small as 1/4 inch for use in the biomass/pellet industry.
The most productive portable drum chipper in the industry has become even better. The Morbark 50/48X Whole Tree Drum Chipper was updated to a similar design layout as Morbark’s other industry-leading industrial drum chippers with a sloped infeed, reverse-pivot top feed wheel, bottom feedwheel, externally adjustable anvil and Advantage 3 drum assembly that can come as 10-knives for fuel chip or 20-knives for micro-chip applications. Making it easier for customers to perform routine daily maintenance and increasing performance and production guided the new improvements, which include large work platforms, an enhanced hydraulic system and an enlarged top feedwheel.
Acrowood has long been known as a chipper manufacturer. From 42-inch diameter disc Rechippers to 175-inch diameter whole log chippers, Acrowood and our predecessors Black Clawson and Sumner Iron Works have supplied chippers and forest products equipment for over 100 years. Since the 1960’s, our slant disc chippers have seen wide spread acceptance and use in waste wood chipping applications. In recent years, there has been increasing utilization of smaller diameter stems. The Acrowood Slant Disc has also proven a great choice in for chipping these small diameter stems. Delivering high quality chips for both pulp mill and pellet mill.
The Andritz BioCrusher BSX is designed for high capacity crushing of bark and breakage from the log debarking process, including difficult-to-handle wood species like eucalyptus and acacia. These wood species, as well as the easier ones like pine, spruce, and birch are crushed into uniform, optimized particle sizes. The BioCrusher BSX spreads the material efficiently, thus utilizing its full width for the crushing action. This results in efficient plug-free operation, with more even wear and tear on the crusher knives, resulting in higher availability lower cost of maintenance.
USNR’s Wastewood Chipper is a powerhouse that comes in four sizes and three configurations, handling logs from 11- to 22-inch diameters. Basic horizontal feeding needs no special installation layout, while gravity feeding handles high volumes. The J-spout design has a higher capacity typically fed by a vibrating conveyor. All models accommodate bottom, rear, and top discharge. The helical knives of USNR’s Norman Chipper slice uniform chips instead of scraping them from the stock, thus eliminating sawdust, slivers, and oversize split ends. Handles logs from 8.25- to 22-inch diameters.
The CBI Magnum Force 6800CT Horizontal Grinder has been engineered to surpass every horizontal grinder that came before it. Improving on the 6800BT’s revolutionary design, the 6800CT has a 15 per cent larger screening area, wrapping more than 190 degrees around the rotor, allowing production rates to surge beyond 200 tons an hour. Supported by a larger shaft and bearings and an optional 1,200-hp CAT C32, the engine powers the forged drum rotor through the toughest materials. The design of CBI’s offset helix rotor minimizes energy loss from each strike and distributes material evenly across the 24 hammers, requiring less power while out producing the competition.
Stringer Industries manufacturers its own line of waste wood chippers and waste-reduction hogs that are designed and built to improve a mill’s bottom line. The Stringer chippers are available in a 48-, 60-, and 70-inch disc. Not only do they have a maximized throat size to handle large slabs, but they also have a cutting action that utilizes the entire knife. The Stringer chipper comes standard with the following features: Easy-Change Clamping System that allows the knives to be changed by one employee; NCK Holders that eliminate the need for counter-knives; Helical Wear Plates that draw wood up the side of the spout. The Stringer hogs are built for dependability and ease of maintenance. The hammers are available with replaceable, carbide-welded tips. Sizes range from a 12-inch opening to a 54-inch opening.
