Trough chain conveyors – how to prevent wear?
A municipal thermal power plant wishes to prevent progressive wear in their trough chain conveyor. These units are used to collect and transport away ash and slag from the combustion of e.g. coal under the boiler. The hard material often causes rapid abrasion of the floor and side walls. The operator of the thermal power plant was looking for a wear protection solution to avoid the costly repairs and shutdowns of the plant. Kalenborn received the order to line the trough chain conveyor with ABRESIST cast basalt plates. The product is characterised by a very hard but smooth surface that reliably protects against abrasive wear and the build-up of material being conveyed. ABRESIST is resistant to corrosion, insensitive to chemical substances and at the same time temperature resistant up to 350°C. Kalenborn lined the component in only three days. The simple and quick installation, plus the cost-effective wear-resistant material ABRESIST. An economical solution for a small power plant to ensure plant availability.
