Coal Feeder Chain

This type of conveyor chain is mainly used in captive power plants, power plants to feed coal from storage hopper to the boiler. This chain is suitable in abrasive, higher temperature & dusty conditions. Précised alignment of chain with sprocket due to appropriate tolerance is maintained by precision manufacturing processes. Maximum chain strength & wear resistance is achieved by selection of appropriate raw material. We are exercising the strict control on procurement of genuine raw material as per specifications & adopting modern heat treatment “in-house” processes. As a result the components subjected to sprocket are able to withstand the sprocket tooth impact. Chain links are made from medium carbon alloy steel. These links are subjected to operations like blanking & fine boaring, which are carried out on highly precision machines. The link hole size & finishing is controlled to suit adequate interference fit. Further links are hardened & tempered to avoid linear elongation & to get better impact strength followed by shot peening process to improve the fatigue strength. Special alloy steel is used for pins with volume hardened & tempered to get the maximum core strength & followed by induction hardening to achieve armored case depth for maximum wear resistance. Special alloy steel is used for bushes with adequate heat treatment. Optimum case depth is achieved to provide maximum wear resistance & core strength by case carburizing. Medium carbon steel is used for rollers with appropriate heat treatment. Alternative sizes are available on request.
