Slag Processing Plant in Down Under
The Australian waste management industry has long been struggling with increasing amounts of waste. For decades, large quantities of waste were mainly exported and recyclable materials had to be disposed of on waste dumps due to a lack of local recycling capacities. The now legally regulated step-by-step ban on the export of certain recycling materials has led to the construction of the first two thermal recycling plants on the west coast of Australia. The Loibl Förderanlagen GmbH as a renowned partner of international plant manufacturers for thermal waste processing plants has been involved from the very beginning and supplies know-how and equipment made in Germany.
After the Loibl Förderanlagen GmbH already received the first order for the delivery of an ash transport system for Australia's first waste incineration plant, the company also received the order for the planning and delivery of a slag processing plant for the second WtE site on the west coast of Australia. We will deliver the ash transport system as well as the first fully automated slag sorting and processing plant in Australia. The entire slag processing plant construction - from the feed bunkers to the different sorting areas - will be planned, designed, manufactured, and commissioned by Loibl.
Powerful slag preparation. The still untreated slag coming from the incineration is transported via conveyor belts to a pre-treatment store. There the slag is continuously and automatically distributed and temporarily stored for some time. During the so-called maturing process, the production-related moist slag is dewatered. The end product is then fed to the slag processing plant. In the slag processing plant from Loibl, the slag is fed to various sorting and conveying systems during the entire processing process. The entire plant, including the necessary steel structure, is designed and delivered by Loibl in accordance with Australian requirements.
Effective sorting. The slag is first conveyed to a feed bunker where a coarse separation (oversize) of the FE metals takes place. A troughed belt conveyor transports the slag to the next station, where crushers crush the material. Material with oversize, which should not enter the crusher, is sorted out beforehand by means of a distribution station. Filter systems at transfer points and sorting stations ensure that the dust is reduced.
The material coming out of the crusher is fed via appropriate conveyor systems to the following sorting devices for further processing. There, there are screening devices which sort the slag according to grain size and transport it away by means of various conveyor lines. At this point, ferrous separation takes place with the aid of magnetic separators. Coarser residues are manually sorted in a sorting cabin. The air-conditioned sorting cabin is designed according to ergonomic standards and meets Australian work and safety requirements. Non-ferrous fractions are automatically sorted and separated by eddy current separators. A magnetic drum separates the remaining ferrous components from the slag. The slag thus processed is sorted into different grain sizes from 0-200 mm diameter using suitable screening techniques and temporarily stored in boxes provided for this purpose, from where it is transported further for further use. Ferrous and non ferrous and components are further processed in the recycling process.
Profitable end products. Separated metals such as iron, copper, aluminum and brass are efficiently separated from the slag by this process and made available in a single type. The processed slag can be used as a basic material in road construction and civil engineering, among others.
