  Research on impact characteristics of screening coals on …

  2019418 · The analysis results indicate that the impact force decreases as the amplitude, frequency, and inclination angle increase, and increases as the vibration direction angle increases. The effect of each factor on the impact force within the level range is in the decreasing order: inclination angle, vibration direction angle, frequency, and amplitude.

  Factors Affecting Screen Performance - vrvibratory

  Factors Affecting Screen Performance. This phenomenon occurs as vibration is passed through a bed of material. The vibration of. the machine sifts the material bed so that finer material passes through the coarser material. This enables particles smaller than the mesh of the screen to pass through it. It is the depth of the material on any ...

  Frequency Vibration - an overview | ScienceDirect Topics

  Frequency Frequency is defined as the number of repetitions of a specific forcing function or vibration component over a specific unit of time. Take for example a four-spoke wheel with an accelerometer attached. Every time the shaft completes one rotation, each of the four spokes passes the accelerometer once, which is referred to as four cycles per revolution. …
