FUNCTION The function performed by the conveyor belts as an essential element of the set of equipment at a sorting facility is to transport the waste flows from one equipment to another in order to complete the treatment processes. DESCRIPTION They consist of the following main elements: • Two revolving drums placed at the forward head and return end. • A drive system with a gear reducer, generally in the head drum. • A strong structure made of rolled profiles with supports constituting the frame. • Intermediate forward or upper roller stations. • Intermediate return or lower roller stations. • An endless rubber belt with a traction-resistant weave and anti-organic coating for the transport of the materials stream. • An effective continuous belt cleaning system (scraper). • A belt centring and tensioning system. • Loading and unloading chutes. • Set of side walls and lips to prevent spillage. • Cover or hood when necessary. TYPES Conveyor belts can be classified according to various criteria: • In view of their function, they can be classified into: conveyor belts designed and used exclusively to transport waste from one unit to another at the facility; manual sorting belts used to perform manual sorting or material quality control, which must be horizontal and have low speed; and acceleration belts in optical separators which have a higher speed to stabilise the material for subsequent optical reading. • According to their position in the plant implementation, they are classified into: inclined belts, horizontal belts and mixed belts which have an inflection point at some stage in their path. • According to their cross-section, they are classified into: V-section belts, trough-section belts, flat section belts and belts with a special cross-section for manual sorting. • Depending on the type of coating of the band they can be classified into: smooth surface, rough surface and ribbed surface. This characteristic is related to the material transport capacity with high belt inclinations. Conveyor belts
