我矿是为宣化钢铁公司烧结和炼钢而生产镁白灰及钙白灰的炉料基地。随着钢铁行业的发展,对白灰的质量要求越来越高,要得到高成分及高活性的白灰,首先要把好入料关,达到“吃精料”,质量和产量才能提高。目前我矿有三孔竖窑,采用的是人工小车推,倒入料钟(料罐)经天车提升到窑台,? Mine is a sinter base for the production of magnesium lime and calcium lime for the sintering and steelmaking of Xuanhua Iron and Steel Company. With the development of the iron and steel industry, the quality requirements of white ash are getting higher and higher. To get high ash content and high activity, we must first put the material into the material and reach the goal of “eating concentrate” so that the quality and output can be improved. At present, I mine a three-hole shaft kiln, the use of artificial car push, pour into the material bell (material tank) by crane to the kiln platform,?
