筛分是选矿所有单元作业中最普遍采用的一种作业。其应用范围从大块筛分中等粒度分级到细粒分离和脱水。基于水力分级且粒度重叠的细粒分离才是真正的筛分。现今筛分机和筛分介质的种类比以往更加广泛和多样化。在金属矿业中,矿石几乎都要破、磨,筛分只是控制分段破碎的一项作业。一般情况 Screening is one of the most commonly used jobs in all unit operations of the beneficiation. Applications range from bulk screening to medium-sized grading to fine-grained separation and dehydration. Fine-grained separations based on hydraulic classification and particle size overlap are the true screening. Today’s screens and screening media are more diverse and diverse than ever before. In the metal mining, almost all the ore to be broken, grinding, screening is only an operation to control the fragmentation. generally
