Project Description






Radial grader

Categorie: Grading

The Allround Radial grader is equipped with lateral placed grading rolls out of stainless steel.
The distance between these rolls changes in steps over the different grading stages. Conveyor belts are placed under the machine, one for each grading size.

When the distance between the rollers changes above the size sections, every second roller lowers its position. This ensures a proper positioning of the product between the rollers. The speed is adjustable by frequency control, and the machine is equiped with a special greasing system.

Options

​​Stainless steel plating

If needed, the machine can be fitted with stainless steel plating.

Brush

When dry products are graded, it is necessary to opt for the optional brush. This brush cleans the rollers of the machine from dirt or dust that sticks to the rollers when grading dry products.

Reverse switch on the transport belts

In some cases it is needed that the outlet belts of the grading machines are able to transport produce to two sides. Therefore, Allround VP offers an optional reverse switch for the transport belts.

Fall dampers

When the belts directly fill boxes, optional fall dampers can be fitted to reduce the falling height.

Bag holder

Customers may choose to fill bags directly from the grading machine. For this situation, Allround VP offers a bag holder to simplify this process.

Roofs sticked with rubber

When very delivate product is grader on an Allround VP grading machine, the roofs can be sticked with rubber, which reduces the falling height.
