硫铁矿煅烧渣配制生料取得成功 江西东方红实业股份有限公司采用硫铁矿煅烧渣替代普通铁矿配制生料烧熟料最近获得成功。 该公司原采用普通铁矿配制生料煅烧熟料,这样配制的生料易烧性差,使窑况系统工况和熟料质量不稳定,设备运转率与窑台时产量较低、能耗高。为解决这一问题,该公司根据硫酸盐矿物可以降低多元系统的共熔温度的原理和硫化物在立窑煅烧过程中转化成为高活性矿物这一特征,在生料中改用硫铁矿煅烧渣替代普通铁矿做铁质校正材料配制入窑生料。实践证明,新方配法不但改善了生料的易烧性、
Preparation of pyrite calcined slag success of raw materials Jiangxi Dongfanghong Industrial Co., Ltd. using pyrite calcined slag instead of ordinary iron ore preparation clinker clinker recently succeeded. The company originally used ordinary iron ore raw materials calcined clinker, so prepared raw materials easy to burn poor, the kiln system conditions and clinker quality is unstable, the equipment operating rate and kiln output is low, high energy consumption . To address this issue, based on the principle that sulphate minerals can reduce the eutectic temperature of multiple systems and the conversion of sulphides to highly active minerals during shaft kiln calcination, the company switched to pyrite calcination in raw meal Slag replacement iron ore normal iron ore preparation of raw materials into the kiln. Practice has proved that the new side with France not only improve the burnability of raw materials,
