5000t/d窑煤矸石配料注意的问题

Problems need to be notice in material proportioning of coal gangue for 5000t/d production line

山东东华水泥有限公司5000t/d生产线,是山东省淄博地区首家全部长期使用煤矸石配料的水泥生产企业,且所生产的水泥质高价优,成本低,效益明显。因煤矸石成分波动大且有害成分较高,用其配料生产时,一要注意与其他原料的配问题,并要摸索出最好的熟料生产三率值配料方案;二要控制好熟料中硫碱比值;三要做好预均化,做好操作参数控制。东华公司用煤矸石配料时,控制三率值为:KH=0.90±0.02;SM=2.55±0.10;IM=1.50±0.10;熟料硫碱比控制≤1.0;所生产熟料达到生产52.5级硅酸盐水泥标准。

Shandong Donghua Cement Co.,Ltd. has a 5000ffd production line. The Donghua company is the fIRst enterprise to use coal gangue in material proportioning for long term in Zibo city of Shandong, and produced high-quality favourable-priee and low-cost cement, the economic benefit was obvious. Because there are high content of harmful component and the components content fluctuate greatly, when use it as raw material, we must pay attention to three kinds of problem, the first is to attach importance to matching with other raw materials and find out the best three modulus; the second is to control the rate of sulfur and alkali; the third is good preblending and parameters control. For Donghua Company coal gangue proportioning, the modulus is as KH=0.90±0.02;SM=2.55±0.10;IM=1.50±0.10, rate of sulfur and alkali equal or less than 1.0 and the produced clinker can reach the standard of 52.5 grade Portland cement.
