For grading potatoes, onions etc.

G DA Roller graders are designed to grade potatoes,
onions etc into different sizes. Grading takes place
over rotating rollers with the help of square shaped
discs. Graders are available in three lengths, 800 mm,
1 300 mm and 1 700 mm to give 2, 3 or 4 grades
respectively. They can be manu-factured in widths
of 600, 900, 1 200, 1 500 or 2 000 mm to meet varying
capacity requirements. The disc mesh remains square,
ensuring accurate grading. Mesh settings can be made
in an instant with the help of a motor, so that no separate
riddles are required. The graders are fitted with feed units
to give consistent grading and cleaning of the riddle surface.
