摘要
振动筛进料速度是筛分过程中重要的影响因素,通过控制变量法研究了振动筛进料速度对筛分时间、筛分后重量和粒度变化的影响。结果表明:模具钢粉末在振动筛筛分过程中,碟阀角度大小对筛分后的粒度值和重量没有明显影响。随着电磁给料速度的增加,筛分完成时间逐渐降低,除了+105μm外,其余各段粒度均降低。最佳工艺参数值为碟阀10°、电磁给料速度10 Hz。
The feeding speed of vibrating screen is an important factor in the screening process.The influence of feeding speed of vibrating screen on screening time,quality and particle size after screening was studied by variable control method.The results showed that the angle of the valve has no obvious effect on the size and weight of the steel powder.Thus,the screening completion time gradually decreased with the increase of the electromagnetic feeding speed.And the particle size of other sections decreased,except 150μm.The best parameters used for qualified particle size value are disc valve 10°and electromagnetic feeding frequency 10 Hz.
