Every cement branch of Conch Group have adopted
Large cement predecomposition kiln has become the core equipment of cement industry. The castables used in kilneye and drop-coal pipe is severe to working environment and requiring highly to fire-proof material capacity. So it is the key to improve production efficiency. The kilneye of large cement predecomposition kiln and castables of drop-coal pipe have used in ten production lines (from 2000ton/day－10000ton/day) , and the average service life is above 8 months, double that of original material. And they bring in large economic benefit to customers, getting high appraisals. The products have formed a series, used in the cover of wicket, cooler, cylinder of wicket etc.
