The average of this value per rotation is a replacement for sound (after all, sound is just the sum of the vibrational energy around the SAG mill shell propagating through air).
the following guidelines to assess the savings possible after installation: 1. Decrease in power consumption of the mill (estimate: 4 to 8 percent). 2. Replacement cost of trommel screen. 3. Annual maintenance of trommel screen. 4. Reduction in mill work index (estimate: 10 percent). 5. Replacement cost of hydrocyclone lines or pump components.
