The product is specially designed to detect the load status of various mills. It is widely used in the load status detection of the first, second and third-stage mills in the grinding operation area in the mineral processing industry. It is the core detection instrument in the grinding expert system of our company. Fundamentally solve the problem of mill load status detection, which has a great effect on production process control and efficiency improvement. With the on-site automation system, the mill operation rate is improved, the mill failure rate is reduced and the concentrate output and grade are improved. The metal recovery rate brings considerable economic benefits to the enterprise. 

The Mill Sound Spectrum Analyzer is a non-contact online detection instrument that feedbacks the load status of the mill by detecting the sound signal sent by the mill. It adopts advanced technology for complex and changeable mill noise signals. The signal acquisition and processing module adopts Wavelet transform and FFT processing technology for the mill noise signal, which can practically improve the accuracy and sensitivity of mill load detection. The unique sensor structure design concept enables the product to provide stable and accurate data under harsh working conditions, which greatly reduces the amount of daily maintenance. It is widely used in the automation control projects of major mining enterprises and it also can be applied to the overflow ball mill, grid ball mill, semi-automatic mill, self-grinding and other mills are tested for the status of various mills, and cooperated with the automatic control system to ensure that the mill is working under a good load condition to increase production and reduce consumption of the mill. The purpose is to improve product quality.

1.Different from traditional electric ears, it uses time-frequency joint analysis technology to analyze characteristic noise signals. 

2.Master the noise spectrum structure of various mills and professional big data spectrum analysis technology. 

3.The dual-channel design of time domain analysis and frequency domain analysis has stronger on-site adaptability. 

4.The core detection instrument in the grinding expert system provides stable and accurate mill load data.
