The discs operate at tip speeds of 21-23m/s resulting in high energy intensities of up to 300kW/m3. Figure 2 illustrates the layout of the IsaMillTM.

SAG mills are going to be very sensitive to ore hardness and over-grinding is a very real issue. the cost of a skid mounted crushing machine out of china is now so cheap why would you bother. Bang in one of these from China, get yourself a decent stockpile and then a single stage ball mill which will be a lot more stable to run. ... The general ...

The BGM comminution circuit includes a primary crushing stage with a gyratory crusher and a two grinding circuits using a Semi-Autogenous Grinding (SAG) mill and a ball mill. The SAG mill...

A. The cost of a Sag Mill can vary widely depending on its size, capabilities, and complexity. Most of the price of Sag Mill ranges from US $ 2500 to $ 3000000 per Set. It's important to research and compare different models and features to find the best Sag Mill for your needs and budget. Q.
