What are LogRippers® machines?

LogRipper is a family of sawmills for primary wood breakdown.
There are few models of LogRippers available:

LogRipper-160
unique sawmill for short & small logs 
Input raw log diameter range: 50-250 mm (2-93/4") 
Input raw log length range: 1-6.5 m (40" - 21 ft)
Troughput: up to 9 m/min (30 ft/min)
Productivity: up to 30 cubic meters (12.5 MFBM) of milled product per workshift
LogRipper-360
sawmill for short logs 
Input raw log diameter range: 120-400 mm (43/4-16") 
Input raw log length range: 1-2.5 m (40" - 8") or longer by special order
Troughput: up to 27 m/min (90 ft/min) depending on chosen power of motors
Productivity: up to 100 cubic meters (42 MFBM) of milled product per workshift, depending on surrounding infrastructure and chosen motor power
LogRipper-460
sawmill for bigger logs 
Input raw log diameter range: 120-460 mm (43/4-18")
or by special order up to 510mm (20")
Input raw log length range: 3-6.5 m (10 - 21ft) or longer by special order
Troughput: up to 27 m/min (90 ft/min) depending on chosen power of motors
Productivity: up to 250 cubic meters (100 MFBM) of milled product per workshift, depending on surrounding infrastructure and chosen motor power

  

LogRipper-160

Effective sawmill for small & short logs. 

 
 
This is unique "next generation" sawmill for small logs.
Input raw log diameter range: 50-250 mm (2-93/4") 

Input raw log length range: 1-6.5 m (40" - 21 ft)
Troughput: up to 9 m/min (30 ft/min)
Productivity: up to 30 cubic meters (12.5 MFBM) of milled product per workshift

 
 
 

Featiures of the LogRipper-160:

  • Integrated milling cutters for slab elimination (less hard waste)
  • Two spindles for sawing allows to use thinner saw blades what may improve production yield and reduce power consumption
  • Precission +- 0.5mm
  • Automated & quick change of sawn width depending on input log diameter 
  • Integrated VAC system for saw-dust and wood shavings removal 
  • Integrated laser pointers 
  • integrated log in-feed and out-feed (a log is pushed through the saw-milling unit)

LogRipper-360

Log pass-through primary breakdown sawmill
for logs up to 400mm (16") in butt diameters 

 
 
This is "next generation" sawmill for medium logs.
Input raw log diameter range: 120-400 mm (4¾ - 16") 

Input raw log length range: 1-2 m (40" - 6.5 ft).
The feeding system for 6m (~20ft) long logs are optional.

Troughput: up to 27 m/min (90 ft/min)
Productivity: up to 100 cubic meters (42 MFBM) of milled product per workshift, depending on surrounding infrastructure and chosen motors power: 22, 30, 37KW (30, 40, 50HP)

LogRipper-360  Milling principles

LogRipper-360 4 spindes
width adjustment principles


 

LogRipper-360 in-feed

LogRipper-360 out-feed

LogRipper-360 allows quick change
of sawing width on the fly 

from the operator's panel

 

LogRipper-360 is robust & reliable
and can work in rough conditions
from -20..+40 C° (-4..+104 F°)

Featiures of the LogRipper-360:

  • 4 spindles: such desing allows to use thinner saw blades and increase the yield
  • Each spindle is powered by a separete motor
  • up to 3 saw blades on each spindle
  • fast changing of a distance between opposite spindles allows changing the width of a milled 2-sided cants on a fly depending on input log diameter 
  • integrated log in-feed and out-feed (a log is pushed through the saw-milling unit)
  • Precission +- 0.5mm
  • Integrated laser pointers

LogRipper-360  can mill 2-sided cants with
min-max thickness: 70-305mm (2¾ - 12")
min-max width (log diameter): 100 - 400mm (4 - 16")
actual max saw cut: 360mm (14")
