Process for reducing iron oxides in rotary kiln
专利汇可以提供Process for reducing iron oxides in rotary kiln专利检索，专利查询，专利分析的服务。并且A process and apparatus are provided for reducing iron-oxide bearing materials with reduced dust emission and reduced heat loss. The material and a reducing agent are mixed to form a charge which is fed into the kiln. As the charge travels through the kiln it passes through a heat transfer zone and then through a reduction zone. The heat transfer zone includes suspended chains or other such devices which are heated by gases leaving the reduction zone and which pass this heat to the charge. This heat transfer pre-heats the charge and cools the gases to reduce the volume and hence the speed of the gases thereby also reducing the weight of dust and particles picked up by the gases from the charge.，下面是Process for reducing iron oxides in rotary kiln专利的具体信息内容。
