摘要

针对恒速振动电机振动磨在超细粉碎过程中易出现物料团聚而引起颗粒细化难度增大、超微粉碎发展受限的情况，提出振动电机转速、激振偏心块矢径随时间变化的双变激振方式，结合Adams仿真及样机试验对电机转速变化曲线进行优化,从而实现了对高振强特性超微粉碎激励方法的研究。通过模拟分析振动磨机不同转速工况下的运动响应特性、振强变化规律，对电机转速最佳变化范围和组合效应进行研究，以平均粒径为的金刚石粉末为研磨对象进行新型振动磨机的碎磨试验，从而验证了组合优选所得到的电机转速变化曲线能够使得颗粒进一步细化。

Abstract

Material agglomeration is easy to appear during the ultrafine grinding process by ordinary vibration mill with constant motor speed. Because of that,the difficulty to refine the particles is increased and the development of ultra-fine powder is limited. A new excited mode with the motor speed changing over time was put forward,and an ultrafine grinding excitation method with high vibration strength was explored through Adams simulation and prototype experiments. The motion response characteristics of the body,the changing rule of vibration strength and the optimal range of motor speed were obtained through simulation analysis of vibration mill at different speed. Grinding tests on the new vibration mill were conducted with diamond powder as the grinding object,whose average particle size was 10 microns. The results show that the reasonable change of motor speed is conducive to the further refinement of particles.
