Operation                                   Product is fed onto the vibration feeder that separates, rectifies and distributes it evenly to all grading lanes. The product slides down the gradually wider lanes, so the small items fall through first and the large ones further down the lane. Oversized product continues over the end of the rollers.

Construction                              The roller grader is built of stainless steel with maintenance-free closed bearings mounted inside the rollers in a sealed plastic housing. The rollers are driven by round belts that are easily changed.

                                                        The machine consists of four main elements: the vibratory infeed, the rollers, a frame with guide plates on the top of the rollers, plus support and chutes underneath the rollers.

                                                        The vibratory feeder is mounted at the high end of the rollers to lead the product down into each lane via guide plates. The feeder is complete with vibration motors with adjustable stroke length
