Operating procedures and principles of the nut grading machine

  • First of all, the raw materials to be graded should be poured into the hopper of the grader, and the size of the feeding door should be adjusted so that the nuts can be evenly distributed into the graded bucket.
  • The grading bucket is distributed with three holes of different sizes, and is from small to large.
  • The following part of the grading bucket corresponds to the receiving hopper.
  • Nuts also rotate when the grading bucket rotates.
  • Nuts of small size first fall from the hole, and nuts of larger size fall to the next level under the rotation of the drum, and so on, so as to achieve the grading effect.
