3. Mill geometry and configurations for comparison The experimental mill had an internal diameter of 592 mm and a depth of 200 mm. It was a 1:10 scale model of the Alcoa SAG mill at Pinjarra.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the …

Ball Mill Shell Dimensions VS Motor Sizes. Diameters and barrel lengths are manufactured with a modulus of 300 mm (abt. 1′). Tube mills with greater lengths than shown in the table can be delivered. For calculations of power input and critical speed the diameter and length should be reduced with the liner thickness.

An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in $/kWh and the capital cost for the PV-BESS infrastructure, prorated over the life of the battery system, accounting for the discount rate through an annuity factor (Pamparana et al. 2019a, …

's AG/SAG mills accomplish the same size reduction work as 2 or 3 stages of crushing and screening The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an ...

Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, …

SAG Mill Dimensions: The SAG mill was designed for monzonite ore, with allowance in the mine schedule for reduced throughput when treating the harder volcanics. The latter forms -8% of the orebody and have the potential to reduce7 throughput by up to 30% if treated by themselves, while maintaining the same grinding circuit product size. Speed ...
