摘　　要：为提高球磨机的磨粉效率和质量,根据粉体颗粒粒度变化实时调整球磨机运行速度,设计了一种基于粉体图像处理的球磨机自动调速系统。该系统利用高速相机在线获取被磨粉体颗粒图像。上位机通过对图像的分析处理获得被磨粉体物质的粒度,并结合球磨机转速和粉体粒度的对应关系,将速度指令发送给PLC,并由PLC控制变频器,调节球磨机电机转速,使球磨机运行于较佳转速,以利于提高制粉效率,减小球磨机的能耗。To improve the efficiency and quality of ball mill,by adjusting the speed of the ball mill based on the particles size changing real time adjusting,an automatic speed-control system of ball milling was designed based on particle image prosessing.The system can obtain the image of particles online by using high-speed camera.PC obtains the size of particle by the analysis of the image,then sends the speed command to the PLC according to the corresponding relationship between the ball speed and the particle size.PLC control the inverter to adjust the ball mill motor so as to make the ball run at a better speed,which is beneficial to raise the powder grinding efficiency and reduce the energy consumption of the ball mill.
