围绕水泥成品优质、高产、低消耗的目标,阐明了管磨机入磨前除铁以及除去圈流粉磨系统中管磨机内铁颗粒的必要性。在理论与实践的结合过程中,找到了我国部分企业认为圈流粉磨系统不如开流粉磨系统粉磨效率高的真正原因。说明了在使用圈流粉磨系统中的除铁器时必须注意的问题,必将对水泥、矿业等管磨机相关行业技术进步带来积极影响。 Focusing on the goal of high quality, high output and low consumption of finished cement products, the necessity of removing iron particles before tube mill grinding and removing iron particles from tube mill in circle jet grinding system is clarified. In the process of combining theory with practice, we find some real reasons why some enterprises in our country think that circle grinding system is not as good as grinding system of open flow grinding system. The problems that must be paid attention to when using the iron remover in the circumfluence pulverizing system are illustrated, which will surely bring a positive impact on the technical progress of related industries such as cement and mining tube mills.
