Experimental Study on High Intensity Magnetic Separator of Coal of Pingdingshan G Unit

Abstract:

Self-made pairs of pole-type magnetic separator using materials of NdFeB. Permanent high gradient magnetic separator do without excitation current, the equipment with low cost, low operating costs, and highlights the advantages of small floor space, etc. Using stainless steel nets as a poly-magnetic medium, we conducted a dry separation experimental study on high-sulfur coal of Pingdingshan G unit, focusing on the vibration frequency; number of sorting and pulverized coal size, and the effect on the separation. The results showed that: the increase in desulfurization rate and ash removal rate is based on the cost of losses of clean coal yield. When vibration frequency is 50HZ, the pulverized coal with 100-200 mesh through three times sorting, the desulfurization rate and ash removal rate is 28.02% and 22.43%, and the corresponding coal production rate is 80.79%.
