基于高速摄像法粉碎机物料颗粒流场分布研究

The Research of Materials Motion Flow Field Distribution Based on High-speed Photograph Method of A New Type of Hammer Feed Grinder

物料分离过程颇为复杂,分离流道内高速运动物料颗粒流场分布情况的研究也鲜有报道。基于上述现状,使用高速摄像机对新型锤片式饲料粉碎机分离流道内物料颗粒的流场分布情况进行图像采集,并使用PIVlab软件对采集到的图像进行分析比较,找出了物料颗粒在流场中的分布规律,为锤片式粉碎机的进一步优化提供了理论参考。

Material separation process is quite complex , the accurate mathematical model of the separation performance and impact parameters rarely seen, the grinding chamber large number of materials separation process is not clear . To re- solve this issue, use the new high-speed photography method for hammer feed grinder at different speeds, the flow field distribution of the material particles, and find out the movement of the particles in the hammer feed grinder material crushing process.
