在现代高炉炼铁工艺条件下,入炉原料要求整粒、除尘和强度稳定.进一步改善烧结矿和球团矿粒度组成的潜力,还远没有挖尽.特别是烧结矿中5-0毫米粒级的含量仍然不能令人满意.现在用机械筛筛分烧结矿和球团矿的传统方法,均不能保证有效地使粉末,特别是粉尘(1～0毫米)与合格产品分离.筛子存在着许多固有的缺点:有时分离不稳定;操作时排出大量灰尘;各个结构部件寿命短.实际上无法完全消除这些缺点.全苏冶金热工科学研究所(?)设计了两种结构型式的烧结矿和球团矿风力分级装置〔1〕.在该所的试验工厂条件下对
In the modern blast furnace ironmaking process conditions, the raw materials into the furnace requires the whole grain, dust and strength stability .To further improve the potential of sinter and pellet size composition, far from exhausted .Especially in sinter 5-0 mm grain The levels are still unsatisfactory, and the conventional method of sifting the sinter and pellets with a mechanical screen does not guarantee effective separation of the powder, especially dust (1-0 mm) from the acceptable product. There are many inherent drawbacks: sometimes unstable separations; large quantities of dust that are emitted during operation; short life of individual structural components; virtually none of these drawbacks can be virtually eliminated. All-Metallurgical Institute of Thermal Science (?) Designed two structural types of sinter And pellet wind classification device 〔1〕 in the test under the conditions of the factory
