Method for agglomerating pellets containing ultrafine coal powder and ultrafine quicklime powder

Abstract

本发明公开了一种含超细煤粉和超细生石灰粉的球团的造块方法,包括:将超细煤粉和超细生石灰粉进行混合,以便得到含有超细煤粉和超细生石灰粉的混合物料;将所述含有超细煤粉和超细生石灰粉的混合物料与煤焦油进行混合造粒,以便得到预制粒颗粒;以及将所述预制粒颗粒进行成型处理,以便获得含超细煤粉和超细生石灰粉的球团。该方法可以有效解决超细煤粉和超细生石灰粉混合造球难的问题,并且所得到的球团具有良好的冷态强度和稳定性能。
The invention discloses a method for agglomerating pellets containing ultrafine coal powder and ultrafine quicklime powder. The method comprises the following steps: mixing ultrafine coal powder and ultrafine quicklime powder so as to obtain a mixed material containing ultrafine coal powder and ultrafine quicklime powder; mixing and granulating the mixed material and coal tar so as to obtain prefabricated granules; moulding the prefabricated granules so as to obtain pellets containing the ultrafine coal powder and ultrafine quicklime powder. By the method, the problem that the ultrafine coal powder and the ultrafine quicklime powder are difficult to mix and granulate is solved, and the obtained pellets have good cold state strength and stable performance.
