Mechanized strength grading

[two_third_text]
Especially in the context of mandatory CE certification according to DIN 14081, the mechanized strength grading of dried lumber is gaining in importance in sawmills. Mechanized grading delivers reproducible grading results and guarantees a consistent grading process regardless of the subjective performance of sorting staff. While increasing the yield – especially in higher strength classes – the workload for the staff is reduced.

 

Other advantages of mechanized strength grading include:

 

 

So far, systems for mechanical strength grading were extremely expensive and thus hardly affordable for small and medium-sized companies.

 

For this reason, we teamed up with the company Brookhuis and developed the cost-effective, budget-friendly „mtgBATCH“ mechanical strength grading system.

 

Our system:

 

 

Our „mtgBATCH“ system also enables small and medium-sized businesses to obtain CE certification according to DIN 14081 through the integration of mechanical strength grading.

 

Depending on the requirements, the „mtgBATCH“ system can be delivered in a modular, expandable design:

 

  1. Single device
    Integration as a single device offers the advantages of a fully mechanical strength grading.
  2. Version with integrated weighing system
    The yield of higher strength classes is increased by the additional determination of the bulk density. The density is calculated from the weight and dimension.
  3. Version with integrated weighing system and FMI humidity measurement system (recognized by MPA Stuttgart)
    By way of the additional integration of humidity measurement (FMI system), the yield can be further increased; the use of this system prior to bonding (finger joints as well as surface gluing) is approved by MPA Stuttgart.

Of course, we also integrate third-party measurement technology into our systems if required.
