Star rollers

Great accuracy

The unique star-roll (ST) pre-grading system delivers outsized performance. With this, an oversize can be separated quickly and without damage within a continuously adjustable range of approximately 10 mm. The system has more than proven itself in practice, partly because of its high accuracy. Even when processing elongated crops and under poor harvesting conditions. The machine can be mounted directly behind the product cleaner or integrated separately on a chassis in a grading line.

Drive by means of engines and gear units per shaft (0,75 kW per shaft).
Product conveyor under the machines, equipped with belt guidance system for optimal belt control.
Discharge conveyors with double directive, so unloading at the left or right side of the machine can be easily set.
Distance between the rollers adjustable through hydraulic pump unit or hand spindle, settable from 5 - 59mm.
Bearing of the rollers through double bearings.
Easily adjustable angle of inclination.
Possibility (aftwerwards) to incorporate a continental web, thus increasing the cleaning capacity of the unit and to create a possibility for sorting.
Suspension of the rollers by means of a proper scissor construction.
BLC Line Module System.

Version with 7 or 8 rollers instead of 6.
Frequency converter onto drive of the pre-grader.
Undersize conveyor, slidable on rollers.
Electrical connection for an extra conveyor.
Supporting frame to use the machine as a standalone unit.
Product conveyor behind a standalone pre-grader (length is equal to conveyor for the undersize).
