CHIPPING

Slant Disc Chipper

Highest quality chipping, economical costs.

Acrowood Slant Disc Chipper

Uniform chips from waste wood or whole logs are produced in the Acrowood Slant Disc Chipper. These machines have been in operation for decades and are proven to save mills money by requiring little maintenance while producing high-quality fiber with minimal pins and fines.

Slant Disc Chippers Features

  • Better chip quality results from the stable feeding and chipping action—a result of less movement in the spout
  • Minimal pins and fines are generated with the accurate knife-to-anvil adjustment
  • No damage to the chips on exit through the clear discharge path, minimizing pins and fines
  • Replaceable wear plates on the chipper disc surface
  • Factory installed knife style options include conventional Babbitted knives, and commercially-available disposable knife systems
  • Reduced maintenance man-hours—most knife changes can be handled by one man from the front of the chipper disc
  • Outstanding bearing life results from hollow shaft, fixed arbor design
  • Sizes from 52″ to 84″ disc diameter available
  • Uniformly sized conventional pulp chips as well as mini- and macro-chips
We have two Acrowood Slant Disc Chippers, one for mill trim ends and one for edgings. Both produce the highest quality chips of any chipper we have ever used.

Slant Disc Chip Quality

Chip quality, installed costs and maintenance costs are the criteria by which all chippers should be measured. Yet they are rarely met by a single machine – until now. Until, that is, the Acrowood Slant Disc Chipper.

Acrowood’s Slant Disc Chippers produce a high-yield, uniform chip quality with low capital investment and low maintenance cost. In fact, it is often cheaper to install a new Acrowood Slant Disc Chipper than to fix an old chipper that needs rebuilding!

A pivoting casing quadrant provides unobstructed access to the chipper disc for knife changes.

Optimum Chip Quality

The Acrowood 6120 Slant Disc Chippers’ unique “dead” shaft design allows the disc to be easily moved towards or away from the anvil. This provides a very tight set-up clearance between the knife and the anvil for excellent chip production with minimal pins and fines.

Chip quality is enhanced by a very short “C” path – the distance from the anvil to the shaft centerline to the middle of the knife on the disc.

The slanted disc and the full use of the wide, flat anvil and orientation of wastewood in the spout yield high chip quality. With the knives cutting downward with the wood in a stable position on the anvil (called the “least energy position” by Acrowood engineers) chipping occurs without appreciable movement, greatly improving chip quality.

All slant disc chippers include an integral motor base for simplified chipper installation.

Optimum Design

The short spout length on Acrowood Slant Disc Chippers allows installation of the infeed conveyor as close to the anvil as possible. This optimizes chip quality by minimizing shingle production caused by “dead space.” The shorter the dead space, the better the chip quality.

Finally, Chips have a free flowing exit path, minimizing chip damage. The optional cyclonic discharge feature further minimizes damage and reduces generation of fines and pins.

The Acrowood Slant Disc Chipper is supplied with facemounted knives and wedges for a damage resistant, simple knife package. All sizes can also be supplied with disposable knives as an OEM option.

Lower Maintenance Costs, Great Parts Life

Acrowood engineers designed the spout to engage infeed material across the whole width of the anvil rather than the narrow area commonly used in other vertical disc chippers. This distributes wear across the entire anvil and knife length, increasing parts life by three to four times.

At Acrowood we believe the best isn’t necessarily the most costly, and we prove it with the Acrowood Slant Disc Chipper. It has the lowest installed cost of any disc chipper on the market.

The horizontal feed system is installed close to the floor with a discharge behind rather than underneath the chipper, eliminating the need for a pit or raising the machine. Simply run a conveyor in, and run a conveyor out. An integral motor base makes installation inexpensive with minimum foundation requirements. Also, a driven sheave is standard.

Slant Disc Chipper Options

Acrowood Slant Disc Chippers can be configured to conform to a mill’s special requirements. Models are available for heavier-duty applications. The chippers can be “untipped” with a different base to become a gravity feed bottom discharge machine, or a different casing and addition of fan blades can convert them into overhead discharge units. Slant Disc Chippers are available in sizes ranging from 42“ to 84“ disc diameter, depending on the application.

Wastewood, rechipping, and small log chipping are accomplished using the 42″, 52″, and 61″ chippers, while large wastewood and whole log chipping are handled by the two 84″ models. Contact Acrowood to see which of these several designs best suits your specific application.

Case Study: Pulping System Sensitivity to Chip Quality

Slant Disc Chippers (or Whole Log Chippers) are the second machine in the pulping process after debarking, the clean logs are rapidly feed into a chipper and cut to specific sizes and length for the pulping application.

VIEW CASE STUDY

Case Study: Chipper Upgrades and Replacements

The change in knife position did not upset log feeding or chip production. It was possible to show that the chipper was taking the logs in at an 11 percent faster rate, but the actual horse power used was lower than for the 8 knife disc! Somehow the new angles used allowed the knives to slice through the wood more efficiently and effectively, actually lowering the horsepower per ton of chips produced.
