Roller grader

The Tong vibrating length grader is most popularly used for length grading carrots and other long-shaped crops. Based on a simple yet effective design, the vibrating carrot grader offers an affordable grading solution. It will reliably perform under the most demanding carrot grading & handling environments. The vibrating length grader is slightly different to the Lift Roller Grader, which grades carrots based on the width/diameter of the crop. The vibrating length grader gently vibrates to spread crop in a longitudinal orientation, across the machine’s stainless steel corrugated vibrating plates. EFFICIENT CARROT LENGTH GRADING Powered by a fixed speed motor, each vibrating plate is separated by an adjustable outlet. As crop passes along the vibrating plates, the longer crop passes over, resulting in shorter crop falling through the preceding incremental outlets. Each of the grades passes onto side projection conveyors and any oversized crop passes over the end of the machine. A popular carrot grader for throughputs of up to 10 tonnes per hour. The vibrating length grader comes in standard widths of 1.2m, 1.5m, 1.6m and 1.8m, with a choice of up to 4 grading outlets.
