通过对现有摇床的运动曲线分析,发现颗粒沿纵向除主要向前运动外,还有部分时间是向后运动,因而降低了设备处理能力。为了保证颗粒完全向前运动,提出了理想的运动周期曲线。待分选的特定矿粒测得必要的运动参数后,通过数学转换求得实际运动曲线。研制出凸轮传动的新型摇床头,实现了该曲线。在实验室通过与6-S摇床对比试验,在同样的分选指标下,可提高处理能力10%。
Through the analysis of the motion curve of the existing shaker, it is found that in addition to the main forward movement of the particles in the longitudinal direction, some time is backward movement, thus reducing the handling capacity of the equipment. In order to ensure the particles move forward completely, an ideal movement period curve is proposed. After the specific ore particles to be sorted measure the necessary movement parameters, the actual movement curves are obtained through mathematical transformation. Developed a new cam-driven shaker head, to achieve the curve. In the laboratory through the 6-S shaker contrast test, in the same sorting index, can increase the processing capacity of 10%.
