Woodlandia LogRipper sawmills
LogRipper is a family of sawmills for primary breakdown of raw wood.
Machines of LogRipper series are effective sawmills for small & short logs.
What are the LogRipper^{®} machines?
All models come with:

the LogRipper200 milling 6x6" (150x150mm) 

Cons:
 User shall provide proper waste management (optional VAC system for the machine is offered separately);
 User has to understand very well the details of how to setup the machine properly (detailed user manuals are 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) 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);
 Number of sawblades installed (more sawblades = more resistance = more power required);
 Condition of the sawblades and cutters (dull tooling does not work, right angle for the sawblades theeth 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 LogRipper200 & 200X?
 Let's assume one needs to mill 6x6" or 150x150mm timbers;
 6x6"x10ft = 30 board feet per piece. 150x150x3000mm = 0.0675 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 LogRipper200 or 200X working with average speed 20ft/min (6m/min) and it can mill 12 such logs per minute then it is 360720 pieces per workshift;
 It means that LogRipper200 or 200X theoretically can mill:
 from 10,800 fbm to 21,600 fbm what is from 360 to 720 pcs of 6x6"x10ft per workshift;
or  from 24.3 cubic meters to 48.6 cubic meters what is from 360 to 720 pcs of 150x150x3000mm per workshift;
 from 10,800 fbm to 21,600 fbm what is from 360 to 720 pcs of 6x6"x10ft per workshift;
 Please note:
 These numbers make sence only for the 6x6" or 150x150mm.
 The actual speed depends on few factors (see these consideratoins above);
 Other profiles can result with significantly smaller production numbers.
For example for 4x4"x10ft (100x100x3000mm) the productivity would be different as 4x4"x10ft = 13.33 boardfoot and 100x100x3000mm = 0.03 cubic meter per piece. So during the workshift one theoretically can mill: from 360 to 720 pcs of 4x4"x10ft what is from 4,799 to 9,598 fbm;
or  from 360 to 720 pcs of 100x100x3000mm what is from 10.8 to 21.6 cubic meters;
 from 360 to 720 pcs of 4x4"x10ft what is from 4,799 to 9,598 fbm;
What about productivity of the LogRipper300?
 Let's assume one needs to mill 10x10" (350x250mm) squares;
 10x10"x20ft = 166.67 board feet. 250x250x6000mm = 0.375 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 30,000 to 60,000 fbm what is 180360 pcs 10x10"x20ft per workshift;
or  from 67 to 134 cubic meters what is 180360 pcs of 250x250x6000mm per workshift;
 from 30,000 to 60,000 fbm what is 180360 pcs 10x10"x20ft per workshift;
 Please note:
 These numbers make sence only for the 10x10".
 The actual speed depends on few factors (see these consideratoins above);
 Other profiles than 10x10" can result with significantly smaller production numbers;
