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" (230-280) logs;
- 2 Saw-blade 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 saw-blades installed (more saw-blades = more wood resistance = more power required);
- Condition of the saw-blades and cutters (dull tooling does not work, right angle for the saw-blades 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 LogRipper-200X & 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 LogRipper-200X or 200XP working with average speed 20ft/min (6m/min) and it can mill 1-2 such logs per minute then it is 360-720 pieces per workshift;
- So LogRipper-200X or 200XP can mill:
- 6x6"x10ft 1-2 pcs/min = 360 to 720 pcs per workshift = from 10,800 fbm to 21,600 fbm (24.3 - 48.6 cubic m);
- 4x6"x10ft 1-2 pcs/min = 360 to 720 pcs per workshift = from 7,200 fbm to 14,400 fbm (14.4 - 28.8 cubic m);
- 4x4"x10ft 1-2 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 LogRipper-300?
- 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 LogRipper-300 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 LogRipper-300 working on average speed 20ft/min (6m/min) can mill 0.5-1 such logs per minute = 180-360 pieces per workshift;
- It means that LogRipper-300 theoretically can mill per workshift:
- from 24,000 to 48,000 fbm what is 180-360 pcs 10x8"x20ft per workshift;
or - from 54 to 104 cubic meters what is 180-360 pcs of 250x200x6000mm per workshift;
- from 24,000 to 48,000 fbm what is 180-360 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;
