摘　　要：主要介绍了交叉式细粒滚轴筛的主要结构、工作原理、控制方式、性能特点,还探讨了在实际投产应用中遇到的因侧壁煤粉板结、煤料变大、粘连筛齿等因素造成的筛分效率低,以及因筛片磨损、筛齿变形等因素造成的交叉筛过负荷跳电问题。通过近3个月的现场分析、改造、试验,以上问题均得到了有效解决,使交叉筛故障次数大幅降低,确保了焦炉正常生产和煤料的稳定运输。This article mainly introduces the main structure,working principle,control method and performance characteristics of a cross-type fine-grained roller screen,as well as the problems of the low screening efficiency caused by factors such as hardened coal powder on the sidewall,increased coal viscosity and coal adhesion on screen teeth and the overload power tripping of cross screens caused by factors such as screen wear and scree tooth deformation in actual production and application.Through nearly 3 months of on-site analysis,renovation and testing,the above problems have been effectively solved,which greatly reduces the number of the failures of cross screens,and ensures the normal production of coke ovens and the stable transportation of coal materials.
