SAG Mill Grinding Circuit Design

Jun 06, 2016 SAG Mill Design and Specification . Considerable variation in ore hardness, the late commissioning of much of the instrumentation and an eagerness to maximise mill throughput led to frequent mill overloading during the first four months of operation. The natural operator over-reaction to overloads resulted numerous mill grindouts, about

SAG Mill Control

stabilise SAG mill load and density by manipulating variables such as feed-rate, mill speed and feed water. You thereby improve efficiency without purchasing new control software or hardware. The MIPAC Approach: MIPAC has successfully optimised SAG Mill control on both fixed and variable speed mills in both closed and open-circuit applications.

Unlock SAG mill capacity with process control optimization

Instrumentation. The instrumentation installed on a SAG mill is integral to control. For example, the mill load and noise sensors are instruments that provide essential information for an optimized SAG mill operation. Insufficient understanding of the ore characteristics and feed composition can result in an ineffective SAG mill operation.

MillSlicer mill vibration analysis Process IQ

The comprehensive 360° mill vibration analysis is displayed as a real-time polar plot and estimates the position of the impact zone. The MillSlicer also determines a Liner Damage Level signal that can be used by the operator to minimise metal-on-metal impact and prolong liner and grinding media life.

AG & SAG Mill Grinding Circuit Automatic Control

Mar 09, 2018 AG & SAG Mill Grinding Circuit Automatic Control. It is obviously well understood that autogenous AG and semi-autogenous SAG mills operate quite differently from conventional rod mill or ball mills. Since these mills are of a grate discharge type, they operate with varying loads, with the power drawn by the mill being dependent upon the

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019 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 materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

Autogenous and Semi-Autogenous Mills FLSmidth

Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.

Maximising grinding mill efficiency with Instrumentation

For SAG and AG mills there is an inverse parabolic relationship between mill power and mill load as shown in Figure 3. Thus maximum grinding efficiency, and therefore maximum production rate, occurs at the point of maximum power on the power/load relationship.

Effect of Mill Volumetric Load Level % Solids & Speed on

Jun 29, 2018 The second major factor which has impeded the development of more advanced and effective SAG mill control procedures is the lack of available instrumentation to measure important SAG mill process variables. For example, the volumetric load level within a SAG mill is perhaps the single most important factor which characterizes the mill’s
