The WG 900 web grader is an innovative and compact grading solution, designed for easy integration into existing crop handling lines. Its height-adjustable chassis and optimized design increase the effective grading area by 15% while maintaining the same overall length, allowing compatibility with existing grading webs. The 900 mm wide rubber web with conical meshes ensures gentle handling and provides an ideal balance between grading accuracy and throughput.
For smooth operation, the machine features an infinitely variable drive and a soft paddle pusher that gently lifts the crop without causing damage. The 800 mm wide grading cross conveyor ensures efficient transfer to downstream conveyors, regardless of their positioning, maintaining a continuous and controlled crop flow.
The WG 900 also offers high flexibility, as multiple units can be connected in series for multi-size grading in a single pass. Its QuickConnect system significantly reduces downtime, enabling fast and easy changes of grading webs to suit different tuber sizes, improving overall efficiency.
Highlights
The WG 900 web grader ensures gentle crop handling through rubber grading webs that provide accurate sorting with minimal impact. A specially arranged paddle pusher lifts the crop smoothly, while optional eccentric agitators create a gentle wave motion for consistent and careful grading.
It offers high flexibility by allowing multiple units to be connected in series, enabling different grading sizes in a single operation. The tandem version with two parallel rubber webs further increases grading capacity, delivering maximum performance for high-throughput operations.
Efficiency is enhanced with the QuickConnect system, which reduces downtime by up to 70% during grading web changes. This allows quick adaptation to different tuber sizes, ensuring continuous operation and improved productivity.
