DYNAGRADE

Timber strength grading with Dynagrade can be done in accordance with most timber standards. Dynagrade allows for timber strength grading for most of the common grades in Europe, such as C18, C24, TR26, C30, T15 and T22, and in North America the MSR grades such as 1650f and 2100f. Dynagrade is also used for grading into Australian grades MGP10 and higher. Dynalyse has the expertise around grading standards and your market opportunities.

Benefits of DYNAGRADE

  • Fast and rational timber strength grading in transfer lines
  • Simple principle – smart design
  • Dynagrade is compact, robust, easy to install and use
  • Wide acceptance

Technical specifications

Dynagrade is based on the measurement of resonance frequencies and length. It is designed to be robust, simple-to-use and offers a wide spectrum of grading applications.

Timber size and length*: Thickness 0.75inch-4inch; Width 2.36inch-11.81inch; Length 3.93ft-23.62ft.

Sawn or planed surface

Dried lumber/timber, cut to angle

Required space: less than 1 meter (3 ft) of a transfer line with lugged chains (standard)

Grade, grading parameter and length output via RS232, Profinet, TCP/IP. Grade also as relay outputs.

Option: Twin solution for sorting before and after the planer, if splitting is done in the planer.

 * Length interval is max 15.74 ft when measured with the optional length reader, i.e. a fixed interval from 3.94-19.68ft  up to 7.87-23.62ft. No limitation in interval for imported length. Various standards and approvals may limit the size and length intervals.

PRECIGRADER

Machine strength grading with Precigrader is based on an accurate measurement of the wood E-modulus (MOE) and wood density of each passing piece. The efficient machine stress grading is done for over 180 lpm. In many cases, the wood E-modulus (MOE) is the governing parameter for a certain strength class and raw-material. This fact and the strong correlation to wood strength makes Precigrader an optimal solution for structural grading of lumber or timber. Machine strength grading can be done in accordance with various product standards and grading rules. Precigrader is developed for machine strength grading of the many typical strength classes in Europe, such as C18, C24, TR26 (UK) and C30, and in North America the MSR-grades like 1650f and 2100f. Precigrader is also used and is very suitable for sorting into the Australian classes MGP10 and MGP12.
