This machine classifies the olives which have different sizes. It is possible to get the olives with the desired calibration from the desired division because the distance between the divisions into which the olives fall while being sieved can be regulated. Olives are transferred to the machine by the feeding band. This feeding band has speed control and supplies goods regularly. The machine is manufactured from stainless steel and high quality plastic elements. Furthermore, special knitted threads are used in the production of the machine for a better calibration.
