How to choose the gravity separation equipment? A list tell you!

Gravity separation equipment is the one which concentrates the ores according to the density difference between valuable minerals and gangue minerals. Besides the density difference between the valuable minerals and gangue minerals, the ore grain size,shape and dielectric properties have an impact on cleaning effect . At the same time, the different gravity separation equipment can receive product quality are also different. Therefore, we should  choose the corresponding equipment according to the material properties and the quality of product requirement.


The following table list all kinds of gravity separation equipment application characteristics and separation size range, for type selection reference.
