Brookhuis offers a variety of strength grading options:
mtgESCAN 60: up to 60 boards per minute
mtgESCAN 120: up to 120 boards per minute
mtgESCAN 180: up to 180 boards per minute

How does it work?

The mtgESCAN system predicts the strength class of a wooden board moving on a cross conveyor by computing the dynamic Modulus of Elasticity (MoEdyn) and the Density (ρ)

MOEdyn = ρV2 with V = 2 Lf

ρ = density, computed from weight and dimensions measurement (optional)
V = longitudinal velocity
L = length of the board
F = frequency of the longitudinal vibration

A mechanical device hits the board in order to create a vibration which is measured by a laser interferometer. The density (ρ) results from the weight measurement (optional) and dimensions settings (either selected from a user interface or as input for the existing production line).

The strength class is then predicted via a mathematical model.

A proven and reliable technique.
