increases system production. In ball mills, less power is required to produce finished cement from HRPpressed material than from unpressed material. High electrical energy efficiency HRP has the highest grinding pressure (KN/m2) of any grinding machine in the cement industry. That means bestinclass electrical energy efficiency.
