[email protected]process of 6 mm ne coal in the compound dry separator, and the separation e ciency of ne coal of 6 mm was improved.As a result, the compound dry separation could adapt to the high e ciency separation of raw coal with full particle size, and increase the productivity of 6 mm materials in the process of compound dry separation.
ultrasonic vibration gas-solid fluidized bed was proposed and introduced to separate fine coals (0.50.125 mm fraction).Several technological methods such as xrf, xrd, xps, and epma were used to study the composition of heavy products to evaluate the separation effect.Results show that the ultrasonic vibration force field strengthens the particle separation process based on density when.
