由于缺乏在线检测技术,当前破碎机一直处于开环运行模式。通过将图像分析技术应用于破碎机上,解决了破碎机出料粒度实时检测的难题,建立了破碎机闭环控制模型,为通过调整排料口大小来实时调整破碎机出料粒度提供了控制依据。另外,为消除衬板磨损对出料粒度的影响,对破碎机衬板磨损预测和自动补偿进行了研究。 Due to the lack of online testing technology, the current crusher has been in open-loop operation mode. The image analysis technology is applied to the crusher to solve the problem of real-time detection of crusher discharge granularity. The closed-loop control model of the crusher is established, which provides the control basis for adjusting the outlet size of the crusher by adjusting the discharge port size in real time. In addition, in order to eliminate the impact of liner wear on the particle size, the lining of the crusher wear prediction and automatic compensation were studied.
