Acrowood has long been known as a quality chipper manufacturer. From 42” disc diameter Rechippers to 175” disc 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. The Acrowood Slant Disc Chipper has proven to be a great choice for the recent increase in the utilization of smaller diameter stems. Acrowood’s Slant Disc Chippers deliver high quality chips for both pulp and pellet mills.

The HHQ-Chipper has a unique chipping geometry and optimized cutting speed that enables it to produce superior quality, thin and square shaped chips, as well as homogenous micro-chips for pellet production at the highest production throughput. The HHQ-Chipper with horizontal infeed is well suited for any log length from shortwood up to tree length. The horizontal feeding of logs through a large spout with a controlled conveyor speed keeps the logs stable and correctly oriented to produce superior chips. Low maintenance requirements, easily changeable wear parts, and ergonomic and compact design all contribute to the total economy of the HHQ-Chipper.

A revolutionary new Wood Hog horizontal grinder, the 3400XT is powerful, productive and versatile. One of the most important features of the 3400XT is its standard width of 8’6” (2.59 m), making it within the legal transport width in any country. The size of the 3400XT allows the same model, using a broad range of engines (from 540 to 800 horsepower (402 to 596 kW) and also electric power options), to be configured for multiple applications and a wide variety of global markets without additional design considerations.

With its 35-inch tall by 60-inch wide opening, patented downward turning cuttermill, and specialized cutting instruments, The Beast cuts more than it grinds, producing more material using less energy and delivering material at a lower cost per ton or yard. A wide array of tooth options are available to cut, split or grind, delivering a uniform product for a multitude of markets.  

Brunette Machinery
Brunette Machinery’s Whole Log Chipper is a horizontal feed chipper with a powered upper press roll and powered lower bedroll to control the feed of the logs to give a high quality chip. Two rotors are available – the standard rotor for up to 1¼˝ nominal pulp chip, and the new MicroChip rotor which is designed to produce a 1/4˝ nominal chip. Each rotor can be outfitted with the standard Brunette quick-change knife system or the ‘disposable’ Key Knife system. The Brunette Whole Log Chipper includes a common sub-frame which ties the infeed, chipper, motor, and HPU together for rigidity, and one lift installation.

USNR’s Wastewood Chipper is a powerhouse that comes in four sizes and three configurations, handling logs from 11”- 22” 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. Models handle logs from 8.25” to 22” diameters. This high-capacity log shaver produces top quality shavings and chips from waste logs and log pieces. 

The Barko CH6025 whole tree chipper offers upgraded components and an enhanced eight-knife design that contribute to optimal operating efficiency.
