MPM Breakdown Software
MPM Engineering has a new generation of their primary log breakdown software, written for
Microsoft Visual C++ and fully object oriented using MFC. The MPM software optimizes logs
for the best lumber recovery based on machine description. It defines the products the
mill wants to cut with the appropriate prices inserted by the operator.
It will define product by volume, recovery, price or customer requirements. What-if
scenarios can be played to determine the best product fit in any given situation or to fit
market driv-en demand. The software is graphically oriented, is easy to use and
incorporates the latest Windows technology, running as Windows 95 or Windows NT 4.0.
The system shows 3-D solutions in any axis and has the ability to rotate the log into any
position and to toggle between the 3-D image, a board-only image, or a log-only image. It
is thus possible to see the whole log and what lum-ber can be cut to the greatest benefit.
Benefits with the new software include increased recovery, better process control and the
ability to custom cut lumber, says MPM. The graphic orientation enables the operator to
pinpoint problems with the process more accurately and quickly.
Redlow Chuck Blade
The Chuck Blade from Redlow
Manufacturing, used with an excavator, is designed for use in site preparation, forestry
road-building and deactivation work. In most materials, it will allow an operator to
excavate and load trucks up to 50 per cent faster than with a standard cleanup bucket,
says the manufacturer. The blade is offered in both hydraulic tilt and non-tilt models.
The tilt model allows the blade to tilt 45° left or right. The blades are built in four
sizes, from 5 to 10" width and 30" to 60" in height. Chuck Blades can also
be used for log loading (with a thumb) and in construction applications including pipeline
News From Acrowood
Acrowoods new Wastewood Rechipper features a V-spout design, which concentrates
chips in the rotor portion of the spout. The new design encourages materials to flow
across the full width of the gravity-fed spout, spreading wear across the full surface and
extending service life. The unit utilizes a single, flat anvil for precise knife-to-anvil
clearance adjustment. It is easily adjustable. Ten knives are mounted on the disc to
provide ample capacity. The chip length is easily adjusted by a simple wedge arrangement
located beneath the face-mounted knife. The flat face plate is composed of wear plates
that are long lasting and easily changed.
Acrowood also has a new V-Rotor Hog for processing waste wood, bark and debris into
useable hog fuel. The Hogs new cutter arrangement and improved discharge grate
result in faster mater ial processing and reduced maintenance, says the company. A series
of cutters, arranged in a V pattern and angled for better performance, are
attached to the Hogs large rotor. The cutters shevron arrangement encourages wood to
travel toward the middle of the rotor, reducing wear on the sides of the infeed chute
housing while reducing side load on the bearings. Diamond-shaped discharge grate holes
offer more opportunity to catch and cut tumbling debris. As the larger pieces are caught
in the grate, the cutters reduce their size in order to fall through the openings.
Chip Moisture Tester
The MDA-100 microwave moisture test station from KDC Technology determines the moisture
content of wood chips in about 30 seconds. A low-power microwave sensor responds to the
dielectric and dissipative properties of the test material (about 0.2 cubic feet). From
these independent measurements, the MDA-100 computes the partial wet and dry densities and
the moisture content of the material. Important density variations are automatically
included when computing the moisture content. For wood chips, typical accuracies are
better than one per cent below 30 per cent moisture and better than two per cent between
30 per cent and 70 per cent moisture (dry basis). Accuracy is greatly enhanced by
repeating the mea-surement several times. System calibration is accomplished using several
samples of test material having known moisture contents distributed throughout the desired
calibration range. Calibration also includes compensation for the test material
temperature above freezing.
Hydraulic Reservoir Water Contamination
Berendsen Fluid Power has introduced two new products that address water contamination
problems in hydraulic reservoirs. The Vickers H2O-GATE vent breather prevents water
ingression in operating systems where the hydraulic fluid is warmer than it is outside,
causing moisture vapour to draw in through the reservoir vent, or when drawn in, due to
cylinder action. It also allows water vapour to escape and will withstand even the most
rugged environments, down to -4°C. The H20-PRO water removal element is designed to
remove free and emulsified wter from petroleum-based hydraulic fluids and lubricants on a
temporary basis. Its super-absorbant media traps the water and prevents it from passing
through the hydraulic system. It has a 32-ounce water-holding capacity, and fits onto OFRS
60, HO22 or HO21/23 filter heads.
CTR has announced two new delimbers: the 314CMD and 314DPM. The 314 CMD is designed for
both softwood and hardwood. The delimber head pivots side to side and up and down,
rotating with the configuration of the tree, and automatically returns to centre after
delimbing. A new base design imposes less stress on the loader. The CTR 314DPM is th e
second CTR machine in its self-contained delimber line.
The new delimber oscillates and rotates with the configuration of the tree and realigns
itself after delimbing. A 17-hp Kubota diesel provides the delimber with its own power
source, eliminating external hydraulic lines connecting it to the loader.
Salton Wet Bulb
Saltons new waterless Electronic Wet Bulb adds to kiln productivity, says the
company. The device uses a silicon chip to measure kiln humidity and it does not rely on
consistent air velocity for mea-surement accuracy. It is designed to be 99 per cent
accurate in rated conditions and is completely compatible with Salton kiln control
systems. Precise readings facilitate more accurate drying schedules, and waterless
operation minimizes the maintenance required by con-ventional wet bulb systems.
A Salton electronic wet bulb system includes a transmitter, which is located on the
outside kiln wall or in the contro l room, and a humidity sensor locat e d inside the
kiln. Operating range for the transmitter is -40° to +140° F. An optional transmitter
cabinet power supply can be installed to extend the transmitter operating range in
severely cold climates. The sensor has a wet bulb sensing range of 32°F to 212° F and a
maximum dry bulb temperature of 356° F.
