Capio Lumber is a successful sawmill in South Africa that
produces structural timber for the construction industry in the region.
A complete Wood-Mizer sawmill line, that has undergone
several upgrades over the past six years, has allowed Capio Lumber to meet its
output targets that have risen consistently since the mill’s start in 2012.
Capio Lumber’s current breakdown capacity consists of three
Wood-Mizer units, an LT20B Electric and two LT70’s.
The second LT70 Remote that went into service in 2016,
assisted to kick the mill’s output capacity up a further notch with an
additional LT40 Diesel now also assisting with log breakdown duties in the
mill’s industrial timber section.
Three Wood-Mizer primary breakdown units in the background feeding into the EG800.
The mill’s secondary processing side consists of three Wood-Mizer
HR200 single head resaws with a Wood-Mizer HR500 double-head resaw and
Wood-Mizer EG300 that followed later adding to the mills secondary processing
and recovery side.
Improved productivity came under the spotlight again in the
third quarter of 2017 when a further mill refurbishment saw the addition of a
Wood-Mizer TITAN EG800 to Capio Lumber’s equipment line-up.
Management is confident that the efficiencies from the
entire line and specifically the EG800, will position the mill for constant
growth into 2018 and beyond.
from Wood-Mizer TITAN EG800
Before the Wood-Mizer TITAN EG800 was installed, the two
LT70’s and LT20 broke the logs down into blocks and sideboards.
Saleable timber from the sideboards was recovered on the HR200’s
and EG300 edger.
The blocks passed through the doubled head HR500 resaw with
two or three end-spec boards exiting.
According to Bruce Moxham, who manages Capio Lumber with
Ross Scorgie, output at the time stood at +-60 m³ depending on log size. Recovery
“Despite the numbers, we knew that we could streamline
the process better and improve overall productivity,” Bruce commented.
“To produce the block sizes for the resaw required
turning the log through four sides. The sideboards that resulted from this took
time, labour and handling systems to reroute to a busy recovery section and we tended
to only recover low value shorts. To produce the blocks also ate into machine
“Efficiency improvements included a more streamlined
material flow that required less labour, less machine time, gave more
flexibility to change board sizes quickly and that fetched better prices and that
allowed us to recover higher value product.
“The introduction of the EG800 has alleviated most of
these inefficiencies,” Bruce said.
Because the EG800 can rip material up to 110 mm thick
with a multi-blade arbour, the cutting patterns for the breakdown units are now
Either cut a two-sided cant that can go straight to the
EG800 or cut the two-sided cant into through-and-through boards before it goes
to the EG800.

At the EG800, the two-sided cants can then be cut into
blocks for further processing on the HR500 double-head resaw, while the through-and-through
boards can be cut directly into end-spec material.
The ripping capacity of the EG800 and the fact that the
arbour can be packed with multiple blades allows for a multitude of product
Less machine movements and sideboards
The initial top-bottom log squaring process is fast (less
machine movements), puts less strain on the breakdown unit, produces only two
sideboards and the operator is less likely to make a mistake. Less mistakes also
means higher saleable volumes and better-quality end product.
Less sideboards also alleviates the pressure on recovery
and requires less labour and material handling systems to move from breakdown
Streamlined material flow
“One of the most important benefits of the EG800 has been
a more streamlined material flow,” Bruce Moxham says.
“Previously, material and material handling systems,
which also required a lot of labour, criss-crossed at various places, which
made the mill very busy. The stop-start process and our inability to find clear
channels that could make the mill more productive, placed a ceiling on further
“Looking at the
final numbers, recovery and output has stayed pretty much the same, but we’ve
managed to recover more brandering ( 38 x 38 mm), which is a good seller.
however, the EG800 has unlocked a more streamlined material flow that has given
us the clear channels we need to now take production to the next level,” Bruce
Unpacking the machine
Wood-Mizer TITAN EG800 Manual Board Edger is designed to offer a twofold
solution to small and medium-sized sawmills.
machine can edge material up to 40mm thick at high speeds (130 m/min) but it
can also run at slower feed speeds to rip material up to 110mm thick.
arbour can be packed with multiple blades. By aligning the incoming board
accordingly, it is possible to achieve a multitude of product sizes, simply and
