| Abstract The effect of the compaction applied pressure , compaction velocity and feed particle size on the size reduction of Alumina Oxide by using the compressibility process were investigated . The apparatus consist of two punches and large die which is a single punch pressing . The applied pressure varied over the range of ( 3.1 to 30.3 ) MPa and the compaction velocity adjusted from ( 0.5 to 100 ) cm / min . Feed sizes used are : 6000,5000,4500,4000 and 3500 m . The ground alumina oxide was screened by sieves analyses method . The increases in specific surface area and the percentages of the losses in input energy for each case were evaluated . The results of this investigation indicated that the high size reduction occurred at a slower compaction velocity and a high applied pressure for all fed particle sizes . These results will help us in the design of mills in order to decreases the losses in input energy for size reduction of solid material . | ||
