“…According to the experimental data obtained, geometric and kinematic parameters of the fill motion at the chamber filling degree κ = 0.35 had the following values: Relation of average sums of vertical components of the collision momenta and the power of these momenta for self-oscillating and steady-state modes per unit time were determined. According to (2), (3), (5) and (6), extreme values of these relations at the chamber filling degree κ = 0.35 had the following values: The graphs of dependences P/P sh for the variable values of numerators P sh аnd P oh during the self-oscillation period at the chamber filling degree κ = 0.25, 0.35 and 0.45 are shown in Fig. 11.…”

“…Parameters of motion of the shear fill layer were established in [4]. Patterns of steady-state fill flow in the chamber cross section were modeled in [5] by an analytical and experimental method. However, the problems of determining the self-oscillating flow of the chamber fill remain unresolved.…”

“…Characteristics of the motion of the shear load layer were established in [4]. The analytical-experimental method of modeling patterns of the steady-state behavior of fill flows in the rotary chamber cross-section was developed in [5]. However, the problems of determining unstable transient behavior of the self-oscillatory flow of intra-chamber fill were not solved.…”

“…Parameters for the flow of a sliding layer of the fill were established in [4]. Study [5] described, based on an analytical and experimental method of research, the patterns in the fill flow in the cross section of the drum. However, the results obtained refer only to the stable steady modes of medium flow.…”

“…We shall further consider the vertical component of the impact action of particles at the surface of transition between zones of the filling's motion for N (ν = 1.2,…,N) grinding particles over an arbitrary time span Δt. Then, according to (5) and (6), expressions for the sum of vertical components of the impact pulses and the sum of work of the vertical components of impact forces over Δt take the following form:…”
