The numerical simulation model of medium flow based on Particle Flow Code (PFC) was established. By setting four kinds of working conditions of amplitude and frequency, the dynamic graphics and curves of the energy field (such as kinetic energy, strain energy, velocity field, force chain and so on) were obtained. In the situation of mid-frequency with large amplitude, the average speed of front medium flow was 1.3\u20135.03 times that of others and the low-energy region was decreased by 6% to 10%. The largest kinetic energy and strain energy were 3.25 and 2.94 times the average value of others, respectively. The diamond UFG was analyzed in new vibration mills under the conditions of low frequency with large amplitude and mid-frequency with large amplitude. Utilizing a laser particle size analyzer, it was discovered that the particle sizes d(50) in these two models were 3.840[Formula: see text][Formula: see text]m and 0.260[Formula: see text][Formula: see text]m and bandwidths were 9.940[Formula: see text][Formula: see text]m and 3.825[Formula: see text][Formula: see text]m. This highlights the effect of mid-frequency with large amplitude in particle refining and bandwidth narrowing, which is of great importance in the fields of ultra-hard particle refining research and energy utilization.<\/jats:p>","DOI":"10.1142\/s1793962318500113","type":"journal-article","created":{"date-parts":[[2017,9,12]],"date-time":"2017-09-12T03:24:33Z","timestamp":1505186673000},"page":"1850011","source":"Crossref","is-referenced-by-count":1,"title":["Numerical simulation and experiment of medium flow energy field in vibrating mill"],"prefix":"10.1142","volume":"09","author":[{"given":"Xiaolan","family":"Yang","sequence":"first","affiliation":[{"name":"Nanjing Institute of Technology, Jiangsu, Nanjing 211167, P.
