MAROT Model C sorting machines sort the grain depending on its width or thickness. The precision of the grading process is obtained by the rotation of the drum whose angle and speed can be changed.
The choice of model is based on the number of separations, products or qualities required, as well as the desired capacity.
The first criterion determines the number of sections/screens (3 to 5) and the second the diameter of the cylinder (630 to 1610 mm). When many separations are required (e.g. for coffee and cocoa), classification is achieved by a combination of modular devices in series or in parallel.
