电石渣首次在新型干磨干烧生产线的成功应用

安徽皖维高新材料股份有限公司为处理排放的18万t／a工业废渣(其中湿排电石渣为7．5万t/a)，决定新建1条1000t/d水泥熟料生产线。在充分分析利用湿排电石渣生产水泥熟料的现状和对电石渣脱水性能的试验研究基础上，采用了温排电石渣的机械脱水处理→配料后用立磨烘干粉磨→采用窑外分解技术进行熟料煅烧的新型干磨干烧工艺，生产出优质高标号水泥。该工程实践的成功，填补了国内在这一领域内的一项空白。

First successful application of calcium carbide sludge on new dry milling and dry firing process cement line

In order to utilize 180 000 t;a industrial waste slag,in which wet discharge calcium carbide sludge amount to 75 000 t;a),Anhui Wanwei Company decides to build a new 1 000 t;d cement clinker production line.Based on analysis state of utilization of wet discharge calcium carbide sludge in cement clinker production and experimental study of the dewater properties of calcium carbide sludge, new dry milling and dry firing process ,mechanical dewatering-use vertical mill to dry and grind proportioned mix-use precalcining technology to clinker buring) project is adopted to produce high strength cement. Practice shows that the project is successful and this technology supplied a gap in domestic.
