摘　　要：筛分是钼粉生产工艺中十分重要的环节,本文结合影响钼粉筛分效率的主要因素,从钼粉的性质、振动筛的筛面结构参数、运动参数3方面,提出了提高钼粉筛分效率的有效途径。通过筛分工艺技术的改进引用高架振动筛和超声波振动筛,将钼粉的平均筛分成品率提高到86.5%。Screening is an important link of molybdenum powder production.Combined with the major factors that affect the effectiveness of molybdenum powder screening,in three aspects,i.e.the nature of the molybdenum powder、surface structure parameter and movement parameter of the vibration screening equipment,effective way was proposed to improve the effectiveness of molybdenum powder screening.By adopting overhead vibration screening and ultrasonic vibration screening,average screening yield of molybdenum powder was increased to 86.5%.
