Case Study - New conveyor system for transporting dry fine slag
Modernization and optimization of dry slag conveying system in Swiss waste incineration plantJuly 2023 - June 2024
Dry fine slag
Customized conveying solutions for dry fine slag from Loibl
The dry fine bottom ash ans slag is conveyed by various conveyor systems from Loibl, which are specially tailored to the customer's requirements. They convey the dry residues efficiently and reliably outside the WtE plant into an existing slag processing hall, where the dry fine ash and slag is sorted by five screens according to grain size for further processing.

Waste incineration plant equipped with modernized conveyor system
The fine slag is transferred to two successive troughed belt conveyors by means of an on-site vibrating conveyor and conveyed over a length of 25 meters and 85 meters. The troughed belt conveyors are completely encapsulated to ensure emission-free conveying. An intermittently operating cleaning scraper in each capsule transports the resulting dust along the entire route to the discharge point, which significantly reduces wear on the equipment.
To avoid emissions, a constant negative pressure is generated in the extracted capsules. The trough chain conveyors have side opening flaps that can be opened and removed for maintenance. They are equipped with sturdy fork link chains to ensure long-lasting operation and replace the more vulnerable round chain system.
In addition to the conveyor system, Loibl is also supplying two support towers and two belt bridges with access on both sides and the necessary platforms for maintenance work. A stair tower in combination with another support tower and platforms provides additional accessibility and support for the conveyors.
The new conveyor system is capable of conveying up to 65 t/h and provides an efficient and safe working environment for fine slag transportation.
