Star rollers (ST)

Product cleaner with star rollers (ST)

The unique feature of the star roller (ST) is that it transports the crop by means of rubber fingers. This eliminates the need for pressure from the supply side and guarantees an extremely product-friendly separation. Stones in the supplied crop are no problem. The cleaner is equipped with a direct drive per roll. As a result, slip and wear are kept to a minimum, guaranteeing a long product lifespan. The product cleaner is available as standard in versions with 7 rollers, but can be expanded with additional rollers for a higher cleaning capacity. Combining several cleaning beds one after the other is also possible with this version.

Drive through motors and reducers per roller (0,75 kW per shaft).
Soil- and crop conveyor (on the product cleaners with a working width starting from 1.600 mm), equipped with convex drums and a belt guiding system for optimal control.
Discharge conveyors with double directive, so unloading at the left or right side of the machine can be easily set.
Stepless adjustable drop from 5 - 59 mm by means of a hydraulic hand pump unit or hand spindle.
Bearing of the rollers by means of industrial bearings, which can be easily replaced from the outside for maintenance and replacement.
Simply adjustable slope of the cleaning system.
Possibility to (afterwards) 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.
