Woodlandia LogRipper sawmills
What are LogRippers^{®} machines?
LogRipper is a family of sawmills for primary wood breakdown.
There are few models of LogRippers available:

LogRipper160, LogRipper160X, LogRipper200
Effective sawmills for small & short logs.
Featiures of the LogRipper160:
 This is unique family of "next generation" sawmills for small & short logs
 Ideal for small/medium size business milling smaller softwood stems (pine, spruce) into palet size boards or timbers
 The operator of the machine can change width of the cut lumber on a fly depending on input log diameter
 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 sawdust and wood shavings removal
 Integrated laser pointers
 integrated log infeed and outfeed (a log is pushed through the sawmilling unit)
All models come with

Input raw log diameter range: 
50250 mm 
50250 mm (29 3/4") 
50280 mm (211") 
Input raw log length range:  16.5 m (40"  21 ft)  16.5 m (40"  21 ft)  16.5 m (40"  21 ft) 
Output lumber/timber up to (HxW):  160x160 mm (6 1/4 x 6 1/4") 
160x160 mm (6 1/4 x 6 1/4") 
200x160 mm (8 x 6 1/4")

What about productivity of the LogRipper160 and LogRipper160X?
 Let's pretend you need to mill 150x150 mm (6x6") squares from 3m (10ft) long logs
 150 x 150 x 3000 mm = 0.0675 cubic meter in one 3m long log
 Lets assume the LogRipper works 50 minutes per work hour in 8 hours workshift = 400 min/workshift
 Then LogRipper160 working on max speed (9 m/min) can mill 3 such logs per minute = 1200 of such logs per workshift
 It means that LogRipper160 theoretically can mill 1200 * 0.0675 = 81 cubic meters or 34325 fbm of 150x150 (6x6") timbers per workshift
 LogRipper160X working on max speed (15 m/min) can mill 5 such logs per minute = 2000 of such logs per workshift
 It means that LogRipper160X theoretically can mill 2000 * 0.0675 = 135 cubic meters or 57200 fbm of 150x150 (6x6") timbers per workshift
 Please note that these numbers make sence only for the 150x150mm. Other profiles will produce different numbers accordingly to volume of wood.

Featiures of the LogRipper360:
 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 2sided cants on a fly depending on input log diameter
 integrated log infeed and outfeed (a log is pushed through the sawmilling unit)
 Precission + 0.5mm
