Roller Grader G D
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.
