Abstract:
The adhesion mechanics of coal and the behavior of the coal
adhesion to the hopper are analyzed. A model coal hopper is
developed, and the model experiments are made by using the
surface electro-osmosis technology according to the processing
conditions. The parameters of the surface electro-osmosis
technology are optimized by the method of orthogonal polynomial
regression designing. The result shows that the surface
electro-osmosis technique is one of the good methods to solve
the adhering problem of coal to the coal hopper in transfer
piping.
Key words: Coal Coal hopper Electro-osmosis Reducing adhesion Experiment
