Product description

Precigrader is a very efficient strength grading system with a capacity of more than 200 pieces per minute.

Precigrader is designed for strength grading according to various standards, such as:
- EN14080 and EN14081 (grades C24, C30, T15, T22, etc),
- MSR production for North America (grades 1650Fb, 2100Fb, etc.),
- JAS laminations for the Japanese market (grades L125, L140, etc).

The use of the dynamic E-modules as indicating parameter results in precise estimates of static E-modules (MOE) and enables reliable prediction of strength. The deensity is derived in the process, and is delivered together with the grade and E-modules to the mill control system.

Precigrader is easily installed in cross conveyor lines. This enables efficient grading directly in a sawmill (green grading), sorting mill or in a planer mill. Less than two meters of an existing cross conveyor line have to be allocated for the operation.

The dynamic working principle is based on the Dynagrade experience. Since many years, numerous Dynagrade units are in use for machine-grading structural timber and glulam laminations for the markets in Europe, Japan, Canada and the USA.

The integration of Precigrader into existing lines with their controls and IT-networks is easily done. Reporting and statistics are available through various options.
