摘　　要：通过实验可得给入细筛的浓度与粒度呈现正相关关系,给入粒度越细,给矿浓度越低。在给矿浓度最高为51.57%,最低为35.19%的条件下,在细筛给矿粒度和使用时间试验条件下,75μm孔径筛网筛分效率都高于其它三种筛网,且在使用180天后的筛分效率可达42.55%。选择最佳的细筛筛网运行条件,在磨矿筛分流程中,可有效降低因细筛筛分效率低导致的球磨机运行负荷增加,岗位职工需频繁更换筛网的压力,及频繁换筛网带来现场安全隐患。It can be obtained that the concentration and granularity of pulp into fine sieve are positively correlated through experiment.The finer the granularity,the lower the concentration of pulp.The screening efficiency of sieve mesh with aperture of 75μm is higher than that of the other three types of sieve mesh and it could reach 42.55%after using for 180 days under the conditions that the maximum concentration of pulp is 51.57%and minimum is 35.19%as well as experimental conditions of granularity of pulp into fine sieve and service time.The increase of run load for ball mill caused by low screening efficiency of fine sieve,pressure of staff who need to frequently change sieve mesh and potential safety hazard on site caused by frequently changing sieve mesh could be effectively reduced by selecting optimal operating conditions of sieve mesh for fine sieve.

关 键 词：筛网 筛分效率 安全
