摘　　要：Up to one million metric tonnes of coal are crushed each year.The crushed coal continually flows through a pipe delivery system at a rate of up to 60 tonnes per hour.In a nitrogen rich environment,the delivery system is constantly under pressure of nearly 9 bar.Filters are used in each pipe delivery system to prevent incorrectly sized material and'foreign materials'from entering the blast furnace.Any incorrect material is held up long enough to be broken-down before becoming small enough to pass through the filter.In the past,foreign materials simply blocked the system.The aforementioned environment creates materials'applications issues.This paper describes how ADI is used to meet these challenging demands in a crushed coal delivery and filtering system.The work described in this paper has resulted in a number of new applications using ADI and CADI materials which are now operating in'waste to energy incineration'plants,aluminum production plants,iron sinter and iron slag processing application,such as rotary crusher,cage crusher,curved door,etc.
