Micromill line of small log processors are the affordable option to
efficiently produce merchantable lumber from small logs.
Worldwide environmental and economic pressures have led wood processing
industries to recognize the potential of smaller logs. The challenges of
handling and processing small logs inspired the development of Micromill’s
mobile small log processor. It can deal with small stems and treetops close
to the source allowing finished products to leave the harvesting area
instead of transporting the waste that comes with round wood.
process 25,000 to 100,000m³ per year, Micromill processors are suitable for
small and medium size operations. They are also viable as a satellite mill
for larger companies interested in pre-processing small logs remotely.
Micromill’s modular design makes assembly and breakdown very simple and
allows frequent re-location with minimum
mill is built in to a standard size shipping container ensuring portability
and eliminating the need for buildings. It can be equipped to be completely
self reliant freeing operation from utilities and infrastructure.
Environmental conditions such as bug kill and forest fire burn areas
represent unique opportunities for the robust,
system. Micromill Operators can take advantage of the short term fibre
supply while avoiding contamination elsewhere.
produces cants and/or dimensional lumber from logs with or without bark in a
The core of each Micromill is the compact saw box containing the unique
chipping head configuration. The two stage system combines a four head
chipping process with double arbor rip
proprietary chipping head design accommodates both a saw ring and finishing
knife configuration. This unique ability allows the mill to be easily
adapted to different fibre sources.
State of the art hydraulic cylinders, with integrated Temposonics, position
the chipping heads through operator input. A central console controls and
monitors all critical functions of the system from one location. Programable
pre-sets allow the operator to change head settings on the fly with the push
of a single button.
Minimizing maintenance cost was an important consideration in the design of
the mill. Good accessibility, clean layout of
and user-friendly manuals contribute to efficiency in servicing the machine.
Every aspect of Micromill’s manufacturing ensures precision and consistent
The solid construction of the entire unit maintains accurate performance and
reliable operation under harsh conditions.
A small crew of 3 or 4
workers can efficiently run the mill under full production.
The mill produces four-sided cants and/or lumber from logs 3-13 inches in
diameter and 5-20 feet long. After rolling off the log
deck onto the pre-feed
table, the sorted logs are transported into the mill. Here the chipping heads
form them into four-sided cants before the double arbor saws cuts the cants into
boards. At the outfeed lumber flows onto a green chain to be sorted.
The chips produced in the process can be contained and used for a variety of
products depending on the chipping knives used and the condition of the logs
processed (bark on or debarked).
The Micromill’s cutting tools
produce lumber with high dimensional accuracy and an excellent surface finish.
A large number of lumber sizes and cutting patterns can be achieved with the
The Micromill saw box is engineered to accommodate quick saw and knife changes
making it easy to maintain the high quality of the finished lumber. The
unique chipping head design virtually eliminates knot tear-out and produces
a valuable, high quality, wood surface well suited for remanufacturing.
Every component of the
Micromill systems can be configured to meet the specific requirement of
The Log infeed can be enhanced with a heavy duty sharp chain pre-feed table.
Optional blowers and conveyor systems are available to propel chips to any
location for disposal, storage or shipping to be further processed.
Diesel or electric power configurations give operators a choice for stationary
or mobile application. Engine horsepower can be matched to processing
On the outfeed side an optional landing table with sweep arms is available for
quick and smooth transfer of lumber onto the green chain. Other Outfeed options
and custom conveyor systems as
well as stacking bins and carts can be utilized
to bring a Micromill operation to the optimal level of efficiency.
Aside from different flow layouts and optional components additional machinery
is available that can turn the basic small log processor into a full scale
sawmill. The Micromill design principles and focus on mobility and reliability
are applied to all additional machinery modules.
