Abstract: By of comparison of heavy medium separation technology and jig separation technology for washing anthracite that is characterized by high degree of coalification,great separation density and extremely difficult washability in Muchengjian coal preparation plant,it is finally determined to choose SKT complex vibration jig as main separation equipment. The application shows that high efficiency separation can be achieved by SKT complex vibration jig with quality products,high separation accuracy and less loss of clean coal. This method can be used as efficient way to separate anthracite with high degree of coalification.
