Frequency Conversion Control for Vibration Mill with High Vibration Intensity Based on Multi-Wave Variable Sinusoid

Abstract

The key technology of vibration machine to finish deaggregation and powder refinement is both high vibration Intensity with a certain frequency and steady vibration of frequency conversion control. A frequency conversion control for vibration mill system based on multi-wave variable sinusoidal frequency ascending and descending cycle curve was developed. The frequency conversion control test of vibration mill was finished through sensing signal amplification, analog digital conversion and on line detection. The results show that the high and super-high vibration intensity with certain action time is produced and the effect of multi-amplitude and multi-frequency is acquired. The experimental data show that the super micro grinding of superfine particles is achieved, energy consumption is reduced, the useful life of wearing parts such as bearing is extended, and engineering effects of deaggregation and refinement of super-hard superfine powder are obtained by frequency conversion control.

Advance Control of Vibration Mill with High Vibration Intensity Based on SCM(III) – Simulation Debugging and Test Comparison Analysis

“…To achieve vibration effect of multi-frequency and multi-amplitude of vibration mill, A intelligent variable frequency advance amplitude reduction control system whose single-chip-microcomputer act as the core controller is built. The multiple wave variable sine vibration frequency curve with increase and decrease periodic cycle is applied as the input frequency curve [1]. By studying debugging and control method, the extreme value point of the vibration intensity and its distribution are forecasted, existing problems is find, and the solutions to this problems are proposed.…”
