Woodlandia LogRipper sawmills
What are the LogRipper^{®} machines?
XP stands for eXtra Power
All models come with:


Cons:
 The machine has to be fixed to a solid fundation to reduce vibrations;
 User has to understand very well the details of how to setup the machine properly (detailed user manual is provided);
 Improper setup of the machine can cause slower speed, sawblades damage & downtimes;
 Produces "hard waste": 2 slabs: one on top, 2nd on the bottom of the milled log;
 6x6" (150x150mm) and 6x8" (150x200mm) only can be milled from small range = 9 to 11" (230280) logs;
 2 Sawblade system may cause the step in the middle of the board (properly set machine shall not produce the step bigger than 0.5mm);

What about milling speed of the LogRippers?
Please note that milling speed greatly depends on:
 Motor power (machine with more powerful motors will be more productive);
 Wood species density (hardwood is harder to mill, frozen wood maybe harder to mill);
 Wood reduction (how much wood needs to be turned into the waste by the chipping cutterheads);
Please consider:
when milling 6x6" from 11" log then the machine has to remove about 2.5" on each side of a log;
when milling 4x6" or 4x4" from 10" log then the machine has to remove about 3" each side of a log;
so the machine can go slower when needs to remove thicker or harder layer of wood fiber.
How much wood % you want to turn into waste?
What is your target recovery % from logs?  Number of sawblades installed (more sawblades = more wood resistance = more power required);
 Condition of the sawblades and cutters (dull tooling does not work, right angle for the sawblades theeth and knife tips is also important);
 Infrastructure & waste management;
 People (yes, people matter as knowledgeable, responsible, caring personnel is one of keys of the success and trouble free operation);
What about productivity of the LogRipper200X & 200XP?
Let's consider 3 scenarious:
 milling 6x6"x10ft = 30 board feet per piece. 150x150x3000mm = 0.0675 cubic meterper piece;
 milling 4x6"x10ft = 20 board feet per piece. 100x150x3000mm = 0.045 cubic meterper piece;
 milling 4x4"x10ft = 13.3 board feet per piece. 100x100x3000mm = 0.03 cubic meterper piece;
 Lets assume the LogRipper works 45 minutes per hour during 8 hours workshift = 360 min/workshift (some time maybe needed for the tooling change, cofee breaks, etc);
 If we assume that the logs are fed butt to butt into LogRipper200X or 200XP working with average speed 20ft/min (6m/min) and it can mill 12 such logs per minute then it is 360720 pieces per workshift;
 So LogRipper200X or 200XP can mill:
 6x6"x10ft 12 pcs/min = 360 to 720 pcs per workshift = from 10,800 fbm to 21,600 fbm (24.3  48.6 cubic m);
 4x6"x10ft 12 pcs/min = 360 to 720 pcs per workshift = from 7,200 fbm to 14,400 fbm (14.4  28.8 cubic m);
 4x4"x10ft 12 pcs/min = 360 to 720 pcs per workshift = from 4,256 fbm to 8,512 fbm (9.6 19.2 cubic m);
 Please note:
 The actual speed depends on few factors (see these consideratoins above);
 Other profiles can result in significantly smaller production numbers.
 Please, watch videos on our YouTube channel to understand what to expect in real life situations.
What about productivity of the LogRipper300?
 Let's assume one needs to mill 10x8" (350x200mm) squares;
 10x8"x20ft = 133.33 board feet. 250x200x6000mm = 0.3 cubic meter;
 If we assume that the logs are fed butt to butt into the LogRipper300 and it works 45 minutes per hour during 8 hours workshift = 360 min/workshift (some time maybe needed for the tooling change, cofee breaks, etc);
 Then LogRipper300 working on average speed 20ft/min (6m/min) can mill 0.51 such logs per minute = 180360 pieces per workshift;
 It means that LogRipper300 theoretically can mill per workshift:
 from 24,000 to 48,000 fbm what is 180360 pcs 10x8"x20ft per workshift;
or  from 54 to 104 cubic meters what is 180360 pcs of 250x250x6000mm per workshift;
 from 24,000 to 48,000 fbm what is 180360 pcs 10x8"x20ft per workshift;
 Please note:
 These numbers make sence only for the 10x8".
 The actual speed depends on few factors (see these consideratoins above);
 Other profiles than 10x8" can result with significantly smaller production numbers;
