MB-Sort is headquartered in Schönberg, Germany, and offers contract sorting of all kinds of complex materials. The objective is to recover secondary raw materials from mixed fractions, for example from WEEE, metal and plastics.
The material to be inspected is fed into a Sesotec Varisort Compact system by means of specifically adapted vibration feeders that ensure a homogeneous material transfer on to the full width of the high-speed belt conveyor. The combination of infeed slide and belt conveyor eliminates form, weight and friction influences of the material that is fed in.
At the end of the conveyor, the material is classified by corresponding sensors. After evaluation, high-speed valves are activated with a corresponding delay time for material discharge. Particles that must be separated are deflected from their original trajectory by targeted compressed-air blasts and fall into a separate shaft.
The Varisort Compact CM+ sorting system is used for shredded small WEEE, to separate printed circuit boards, copper, aluminium, stainless steel and generally remove metals from plastics.
In multi-sensor operation, the C and M+ sensors are combined. The C sensor provides data about form and colour while the M+ sensor is responsible for metal detection. With this combination, a high metal purity can be achieved and a usable plastic fraction can be obtained.
