Wind Jigging for dry coal preparation is the achievements by researchmen after many years hardwork. It is suitable for coal separation with the size range 80 ~ Omm ,low quality coal pre-selection, gangue purification.
The system has the following innovation:
1.Join three function together:first,vibration on bed to sort and throw the material ;second,constant wind ;third,pulsing wind.
2. stepless adjustment of the frequency ,feed ,capacity ,wind and pulsing wind frequency. It is suitable for different coals and can optimize the flowsheet.
3. the combination of process parameters can be stored in the PLC, can be used at any time during preparation.
4, using isotope for density separation on bed materials. Density measurement and control (closed-loop digital control), to improve the accuracy is used for sorting precision.
The system is applied to coal sorting , its biggest advantage is to use wind, not wwater .So it water-saving, environmental-friedly,it solved the problems of dewatering and coal slurry.
Its advantages also cover: low investment, low production costs , quick start. Its application also includes the pre-selection of Low-grade coal, It can increase capacity and reduce the cost in coal preparation plant
Eversince its maarketing ,the system was immediately promated in Inner Mongolia, Xinjiang and other regions and welcomed by customers.
