Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009). However, SAG mill weight,Advanced Simulation for Semi-Autogenous Mill Systems: A,,and process control. SAG mills (see Figure 1) are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their advantages such as higher processing capacity, lower physical space requirements, and lower investment and maintenance costs, as compared to conven tional circuits (Salazar, et al., 2009). Due to the size of SAG mills, pilot plants are,

SAGwise total process control uses specially designed acoustic sensors and proprietary process control software to monitor and respond to critical impacts inside your SAG Mill. Conditions inside your mill are automatically adjusted to minimise liner damage, stabilise and then optimise the operation of a SAG Mill.Increase throughput and capacity in SAG mills,With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life. Every second counts, and adjusting these parameters within seconds can have a significant effect on the wear of your SAG mill, which will effect on your bottom line.

Nowadays, the more successful plants are those that have adopted effective and efficient strategies to optimize their plant operation. As the ‘heart of the plant’ could be viewed as the milling/grinding,Mill (grinding) - Wikipedia,SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m,FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION,SAG mill in closed circuit with hydro cyclones at Freda Rebecca Gold Mine would affect through put and specific energy consumption using an Excel based milling process simulator developed by Hinde, a comminution specialist who has worked for Mintek for many years.Milling Parameters,The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.,,,,,,
