RLM - Machines
One Pass & Done
Rotary Log Molders

What are RLM-series Log Mills?

RLM-machine is One Pass & Done, Multi-Functional sawmill able to work as: Log Molder, Rounder, Profiler, Ripsaw.

RLM-machine has 1 Rotary type milling head and 3 to 5 (depending on a model) profiling/sawing spindles.
The rotary milling head has number of knives which spin around the moving log.
Logs are automatically fed into the milling head and then are turned into into required profile or milled into lumber & timbers by cutters and sawblades installed on profiling/sawing spindles
The unique feature of RLM is an ability to accommodate different Tooling (cutters & saw-blades) to form final product profile.

What Products can RLM mill?

RLM-machine can mill broad range of products in one pass. The product profile depends on installed Tooling.
With the proper Tooling one can mill on RLM: dimensional & custom lumber, squared timbers, round dowels (posts, poles), fencing elements, siding, log home materials.

Why RLM?

RLM machines are high performance machines using "one pass & done" idea
RLM machine can mill up to 5000 linear ft of raw logs per 8-hour work-shift (depending on a model, wood species, profile, infrastructure, etc). Some of our clients report they mill up to 5000 BFM per hour.
RLM machines can mill barked or debarked, dry or "green" stems in one pass
Diversity of output log profiles.
Inexpensive maintenance.
Heavy duty design.
Robust & reliable (if greased on time).
RLM-technology has been used since 1990

RLM machine schematics (RLM-320MF)

Outfeed alignment unit. Function: proper log orientation and infeed into next milling unit
Profile milling unit. Function: form required log profile
Sawing unit. Function: rip sawing of log (if necessary)

Who may need RLM?

RLM-machines are positioned for small & medium size saw-milling businesses who:

mill lumber, squared cants, round dowels, fencing elements, house logs;
look for a way to increase the productivity;
wish to diversify or get into new markets effectively & economically;
need one machine able to produce different types of products;
need to utilize the pine beetle or fire killed stems by milling them into building materials effectively and economically.

What models of RLM are available?

We offer several models of RLM-machines:

RLM-160 for small logs with butts up to 240mm (9 1/2") ;
RLM-200 for small logs with butts up to 260mm (10 1/4");
RLM-260 for logs with butts up to 360mm (14");
RLM-320 for logs with butts up to 420mm (16 1/4");
RLM-400 for even bigger logs;

What are limitations RLM-machines?

It is important to know in prior the following facts about RLM-machines:

proper automated waste removal system is critical because poor waste management can badly affect productivity;
log sorting is necessary for better productivity;
for max productivity automatic in-feed and out-feed log decks as well as in-feed and out-feed conveyors are recommended;
speed of automated in-feed conveyor is to be adjustable to synchronize with the in-feed speed of the RLM-machine.
RLM machine's rotary head can remove up to 5cm (2") on radius or 10 cm (4") on diameter of the log. It means that butt diameter of input raw log must be not more than 4 inches than its top diameter. For example when milling logs on RLM-320 and if output product (dowel) diameter is to be = 12" and top diameter of raw log is 13" than max diameter of log butt must not exceed 12" + 4" = 16";
all parts are metric;
going from profile to profile, may take 1-4 hours, of Tooling re-setup, depending on the target profile complexity.
