Handling equipment - Grading technology | WG 900

Grading width 90 cm and 180 cm with rubber web

The innovative web grader, type WG 900, with its compact design and height-adjustable chassis is easy to integrate into the crop flow. Due to an optimized design the effective grading area could be increased by 15 % compared to the previous model. However, the overall length of the grading web has remained the same, so that the available grading webs of the previous model can still be used. The 900 mm wide rubber web with with conically shaped meshes has only low impact on the crop. It offers an ideal compromise between grading accuracy and flow rate thanks to its infinitely variable drive. A soft paddle pusher in front of the drive drum ensures a gentle crop lifting without damage. The new 800 mm wide grading cross conveyor ensures optimum crop transfer to downstream conveyors, regardless of their angle to the web grader. For grading in different sizes in a single operation-step, several units WG 900 can be coupled in series - simply and without conversion. The unique "QuickConnect" quick-change system reduces downtime by up to 70% compared to conventional web-joiners. Thus grading webs can be adapted to the desired tuber size more quickly and easily.

Gentle grading

Gentle grading via rubber web in 2 grades

The paddle pusher

Special arranged paddle lifter for gentle crop lifting

Several grading sizes

By connecting several WG 900 in series, different grading sizes can be generated in one step.

Maximum grading performance

Increased grading with 2 parallel working rubber webs at the WG 900 tandem

Quick-change system for grading webs

Up to 70 % less down times thanks to QuickConnect - the GRIMME quick-change system to be used for rubber sorting webs.

Gentle grading

One or optionally two eccentric agitators gently wave the rubber sorting web.

Benefits

  • Compared to the previous model, the effective grading surface was increased by 15 %.
  • Gentle grading via rubber web into two sizes with conically shaped mashes.
  • Up to 70 % less down times thanks to QuickConnect - the GRIMME quick-change system to be used for rubber sorting webs.
  • Optimised sorting effect through one or two eccentric agitator, which gently wave the rubber web and lift any stucking crop out of the meshes.
  • Perfect crop protection thanks to specially arranged paddle pusher, so that any jammed crop is gently lifted out of the meshes.
  • The drop step between the rubber graing web and the grading cross conveyor could be reduced by 60 mm compared to the previous model.
  • The 800 mm wide grading cross conveyor ensures an improved crop transfer of the graded crop to downstream conveyor belts.
  • Simple integration into any storage line thanks to a chassis which can easily be adapted in height with support winches (option).
