The Effect of High Pressure Grinding Roller Working Pressure on Bauxite Crushing Effect

Abstract:

Through Changing Working Pressure, the Crushing Tests of Bauxite were Made by Using Laboratory High Pressure Grinding Roller. the Results Indicated that, with Working Pressure Increased, High Pressure Grinding Roller Capacity First Increased and then Decreased. High Pressure Grinding Roller Capacity Reached Maximum when Working Pressure was 9 Mpa, and Reduced Deeply and then Gradually Slowed down when Working Pressure was more than 11 Mpa. the Particle Size of Bauxite Crushing Product P80 Gradually Reduced when Working Pressure Increased from 7 Mpa to 15 Mpa, and Gradually Increased when Working Pressure was more than 15 Mpa. the Working Pressure of 11 Mpa was Appropriate when Bauxite Crushed by Laboratory High Pressure Grinding Roller.
