Mill (grinding) Wikipedia. SAG is an acronym for semiautogenous 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'''' () in diameter, powered by a 28 MW (38,000 HP. Получить ...

known, it is possible to simulate the mill performance. This is essentially equivalent to calculating the effective "mill transfer function" and such calculations are performed routinely by Industrial Systems Ply Ltd to characterise the attainable level of performance such as speed response (subject to constraints on maximum torque on key com
Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

Jan 01, 2018· This harmonic can hide the effect of grinding in the torque signal of actual mills, and thus, it should be filtered in the case it appears in the frequency range of interest (0 to 50 Hz) when applying the proposed methodology. In the case of this study, the mesh frequency is over 50 Hz, so it is out of such a range.

distance to the gravity centre increases and it makes the applied torque higher for the same rotational speed. The power versus speed function is almost lineal in this first stage, because the influence of the speed is much higher than the torque increase (grinding mills are applications of quasiconstant torque). But as the
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

The starting torque characteristic of this type of ball mill is not linear. Figure 2 shows the graph of mill speed versus torque requirement: Figure 2 The graph clearly shows that the torque requirement exceeds 120% at 80% speed. This is why the starting torque of the drive motor should be at least 130% of full load torque.
