Grader Module
HJV Engineering screen systems are robustly built to suit the demands of
today’s operators. Modules can be integrated into mobile systems, static
lines, process intake facilities or used as individual single grading units. The
accuracy of screen grading means this type of technology is very popular
across a wide spectrum of sectors and product types.
STANDARD FEATURES
- Suitable for potatoes, onions, beets and bulbs
- Triple short throw agitators
- High capacity accurate crop grading
- Well proven design and robust construction
- “Push and Pull” drive mechanism
- Simple screen tensioning system
- Optional steel, rubber or plastic screens
OPTIONS
- Separate variable electronic agitation
- Haulm roller assembly at discharge end (removes loose stalks, top etc.)
- Hexagonal steel screens for use on onions and bulbs
- Tuber eject roller (to remove long potatoes from the screen prior to reaching
- the pintle drive roller, therefore preventing damage)
- Seperate variable electronic tuber eject or roller
- Spacer belts to pitch grader cross conveyors to suit automatic box handling systems
- Screen racks to store alternative screens above the module
- Interchange facility to move module on size changes
