Research on Density Control of Wind Jig Dry Coal Preparation System

Abstract:

Article Preview

the paper exposits the purpose and the significance of the wind jig dry coal preparation technology, discuss the working principle and control methods of the wind jig dry coal preparation system. . Based on the dynamic data of the physical density, the control system auto tunes the speed of the opening by utilization of a frequency governor. Therefore, it controls the thickness of the beddepth very precisely and achieves the close loop control in the dry preparation system of coal dressing.Make use of adjustable air pressure and mechanical vibrations of materials according to the density and the particles on the sorting bed for loosing and layered, and using adjustable nesting institutions coal particles of different densities to classify, in order to achieve separation, refuse dumping, desulfurization purposes.
