Sorting of materials MATERIAL 1 MATERIAL 2 MATERIAL 3 MATERIAL 4 CHARACTERISTICS • The material sorting must be performed in specific sorting cabins, which attempt to provide the best possible ergonomic and working positions; accordingly, manual sorting stations must have optimum conditions of climate control and lighting. • Sorting belt speed: the optimum speeds found experimentally in facilities are from 0.3 to 0.4 m/s. Speeds greater than 0.5 m/s are detrimental to the operator’s well-being and comfort, as well as reducing performance. • Sorting height: the conveyor belts must be at a height of 0.75 to 0.90 m from the floor on which the operator stands. Some facilities have a variable height platform that can be adjusted to the most convenient position for the operator. The height of the conveyor belt walls on which the sorting operator’s waist rests must not be greater than 0.25 m. • Sorting belt width: due to the distance that a sorting operator can reach in the sorting belt, for useful belt widths greater than 0.6 or 0.7 m sorting stations must be provided on both sides of the belt. • Distances between sorting stations and col- 2.
