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?

  • LogRippers of 200 & 300 series can be considered as a New Generation Scraggmills for smaller logs (pulpwood).

  • There are few models of LogRippers available:

    LogRipper-200XP, LogRipper-200X, LogRipper-300, LogRipper-200

XP stands for eXtra Power

  • LogRipper-200XP milling motors (2x40HP/30KW) are 67% more powerful than the LogRipper200 (2x24HP/18KW).  
  • LogRipper-200XP milling motors (2x40HP/30KW) are 36% more powerful than the milling motors in the LogRipper-200X (2x30HP/22KW).   
  • More powerful milling motors result in faster throughput.
     

All models come with:

  • Motorized in-feed;
  • Integrated log turner;
  • Out-feed;
  • 2 laser beams;
  • Centering In-feed Roller;
  • 2 cutter heads with knives;
  • 1 set of Spare Knives (8 knives/set);
  • 4 packs of Spare Carbide Tips for the Knives;
  • 20 saw-blades (for softwood);
  • 15HP/11KW VAC system (since 2022);

Pros:

  • Can work in 3 modes: Scragg-mill, Multi-Saw, Slab-Processor;
  • Fairly priced for productivity, features & support;
  • In-feed & out-feed roll-tables are included into the system;
  • 15HP/11KW VAC system included;

  • 2-3 men team: 1 to control the machine and feed the logs, 1-2 to remove milled products and slabs from the out-feed;
  • 2 chiping cutter heads eliminate 2 slabs on sides of a milled log = less hard wood waste than on competitor's solutions;
  • Saw-blades work on "cleaned" surface = longer saw-blade life;
  • 2 blade system allows thinner kerf than competitive 1 blade sysytems;
  • Circular saw blades allow better geometry and consistency of the output products than bandmill
  • The operator can adjust the width of cut on the fly from log to log;
  • Easy & fast change of tooling;
  • Simple to operate;
  • Economical on power than competitive systems;
  • Smaller footpring than competitive systems;
  • Works from ~3 phase, 380V/50Hz (Europe) as well as from ~3 phase, 460V/60Hz (North America);

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:

  1. milling  6x6"x10ft = 30 board feet per piece.  150x150x3000mm = 0.0675 cubic meterper piece;
  2. milling  4x6"x10ft = 20 board feet per piece.  100x150x3000mm = 0.045 cubic meterper piece;
  3. 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:
  1. 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);
  2. 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);
  3. 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 250x250x6000mm 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;
