to an industrial semiautogenous (SAG) mill in Craig and MacLeod (1995, 1996), and the linear model predictive control for an industrial ball mill circuit in Chen et al. (2007). A robust nonlinear model predictive controller (RNMPC) was proposed by Coetzee et al. (2010) to control a ROM ore milling circuit. Full state feedback was assumed.

Grinding Circuit Control Strategy 911 Metallurgist

Grinding Circuit Control Strategy 911 Metallurgist

The grind index is calculated performing a mass balance around the ball mill circuit to estimate the cyclone overflow density (viscosity effect) and a correction factor due to specific power consumption (size effect). The grind cut index is maintained by controlling the addition of water to the cyclone feed. This water control method sets the ...

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Ball Mill Circulating Load 911 Metallurgist

Ball Mill Circulating Load 911 Metallurgist

The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

Calculate Ball Mill Grinding Capacity. The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates ...

Slurry Flow Rate Through a Mill 911 Metallurgist

Slurry Flow Rate Through a Mill 911 Metallurgist

It follows that the average throughput velocity is the quantity of flow divided by the area open to flow. From this average velocity the time for a particle to traverse the mill may be computed. This treatment does not, however, indicate whether, for a given rate of flow, the surfaces of the powder mil the ball charge will coincide or not.

Converting a ball mill from overflow to grate discharge

In operations needing improved grinding circuit performance, the ability to fully utilise the available installed ball mill power will enable higher throughput, a finer grind, or a combination of the two, which will lead in turn to increased production and a corresponding increase in revenue. However, the practical considerations and costs of ...

Abstract. Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best makeup ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range ( ...

As one of the machines widely used in mining, a semiautogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the ...

Once you measure the ball charge and measure the total charges then you need to target an appropriate ball to rock ratio for a chosen mill throughput rate. With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to ) for a coarse mill feed (say F80 > 110 mm).
