Handling equipment - Grading technology | SG unit

Grading width up to 240 cm with PU spiral coils

The separation and pre-grading units of the SG-series are so-called "incomplete machines", which designed for installation in other machines and equipment. Depending on the application the so-called "SG units" can be integrated as pre-assembled module into an already existing processing line, to be used for soil cleaning and/or pre-grading. The soft, wear-resistant polyurethane (PU) spiral rollers achieve lowest impact on the crop and an effective separating performance. The maintenance-free direct drives of the PU spiral rollers, with their infinitely variable speed adjustment, enable a perfect adaptation to all operating conditions and requirements. This drive concept provides the basis for the centrifugal cleaning system, called Turbo Clean, whereby adhering soil is loosened from the PU spiral rollers at maximum speed.

Benefits

Various versions.

The SG unit is available in various dimensions and with different numbers of rollers, depending on the intended use.

Powerful and gentle

For maximum crop protection with the highest separation performance, GRIMME has perfected the soft PU spiral rollers over the years. The soft spiral rollers have a high self-cleaning effect to achieve an optimal cleaning result without obstructions even under difficult, sticky conditions.

Maintenance-free

The rollers are driven directly and without loss of power by one hydraulic motor each. The speed of each pair of rollers can be adjusted independently of each other. Furthermore, the groups of rollers are adjustable in distance to achieve the best results with different crop sizes.

Infinitely adjustment

The speed of the roller-sets can be infinitely adjusted for optimum and particularly gentle crop cleaning and pre-grading. The infinitely distance adjustment of the PU spiral rollers enables quick adjustment of the soil cleaning and pre-grading.

Thoroughly cleaned

The centrifugal cleaning system Turbo Clean offers the possibility to remove sticky soil from the rollers. Turbo Clean is ideal for sticky, adhesive soils. By use of an automatic timer it can be activated without the need for manual intervention.

Lateral discharge

For optimal handling of trash respectively pre-graded crop, the separation and pre-grading units (so-called SG units) can be optionally equipped with cross conveyors for lateral discharge.

• Easy integration into an existing or planned feeding line
• Gentle soil cleaning and pre-grading with PU spiral coils
• Quick adaption via infinitely distance adjustment of the PU-coils
• Efficient and particularly gentle soil cleaning through infinitely variable speed adjustment of the PU spiral rollers.
• The centrifugal cleaning system, called Turbo Clean, whereby adhering soil is loosened from the PU spiral rollers at maximum speed, is standard.
• Maintenance free direct drives
• Available in various dimensions and different number of coils
• The separated soil and admixtures can optionally be carried out of the machine with a soil cross conveyor.
• Pre-graded crop can be moved sideways out of the machine using the optionally available pre-grading cross conveyor.
