Estimation of powder Mass Flow Rate in a screw feeder using acoustic emissions
Powder Technology, 2018Co-Authors: Cristobal Ruiz-carcel, Andrew Starr, Ejay NsugbeAbstract:Abstract Screw feeders are widely used in powder processes to provide an accuRate and consistent Flow Rate of particles. However this Flow Rate is rarely measured or controlled. This investigation explores the use of generalised norms and moments from structural-borne acoustic emission (AE) measurements as key statistical indicators for the estimation of powder Mass Flow Rate in a screw feeder. Experimental work was carried out acquiring AE measurements from an industrial screw feeder working with four different types of material at different dispensation Rates. Signal enveloping was used in the first place to eliminate high frequency components while retaining essential information such as peaks or bursts caused by particle impacts. Secondly a set of generalised norms and moments was extracted from the signal, and their correlation with Mass Flow Rate was studied and assessed. Finally a general model able to estimate Mass Flow Rate for the four different types of powders tested was developed.

Measurement of solid Mass Flow Rate by a non-intrusive microwave method
Powder Technology, 2018Co-Authors: Lei Pang, Yingjuan Shao, Chamin Geng, Wenqi Zhong, Guoyao Liu, Longhai Liu, Wanjun TianAbstract:Abstract The methods of accuRate measurement on the real-time solid Mass Flow Rate are very limited, especially for non-intrusive measuring approaches. This paper presents a non-intrusive measurement system on solid Mass Flow Rate. The measuring principle is based on microwave attenuation theory and microwave Doppler Effect. A series of experiments have been carried out to test the microwave measurement method. The effects of particle properties in terms of size and relative permittivity on the measuring results have been carefully discussed. The correlations between the output signal and the solid Mass Flow Rate have been investigated. The experiment results show that the size and material of the measured solids can significantly influence the reflected microwave signal. To improve the measurement accuracy, the correlation related on the functions of particle diameter and permittivity is proposed for the solid Mass Flow Rate. Furthermore, the experiments under the unsteady Flow condition confirm that this method is promising to be applied in the actual industrial processes.

Effect of axial and radial velocities on solids Mass Flow Rate measurement
Robotics and Computer-Integrated Manufacturing, 2010Co-Authors: Jianyong Zhang, Bin Zhou, Shimin WangAbstract:In coal powder Flow transportation and combustion, powder Mass Flow Rate is a key parameter to be monitored and controlled. Electrostatics is one of the techniques used for such task with its non-intrusive, robust, and low cost natures. The passive electrostatic meters measure charge induced on the detecting electrodes. As it is known that the induced signal is not only dependent on the solids Mass Flow Rate, but also affected by solids velocity. However, the velocity of particles usually referred to is the axial velocity. In reality, the solids velocity is a vector, its projections in both the radial and tangential directions also need to be investigated. This paper analyses the dynamic sensitivity of ring-shaped electrostatic sensors using the finite element method (FEM), and investigates the influence of the axial and radial velocities on the induced signal on the electrodes.
