The key to an efficient grinding circuit.
ECS/ProcessExpert analyses a wide range of signals and actuates automatic adjustments to manage the equipment and process performance resulting in improved grinding efficiency.
Changes in process conditions in a typical minerals plant can result in variable flow through the circuit and delivery of material that is inconsistent with the required target particle size. This unstable performance can reduce the efficiency of the minerals liberation in the downstream processes resulting in lost revenue.
ECS/ProcessExpert monitors operational and process conditions and makes constant automatic adjustments necessary to stabilize the process flow, balance load between circuit equipment and protect equipment, all while ensuring that the circuit delivers a product that matches the required quality.
ECS/ProcessExpert improves the mill circuit grinding efficiency which in turn results in improved energy consumption and throughput. Improved circuit operation together with the increased equipment protection converts to less plant downtime, all of which enhances plant profitability.
Advanced Process Control makes it possible
When human operators make adjustments – whether to the mill speed, pumps, water intake or conveyors – they often choose conservative parameters due to the inability to analyze the multi input/ multi output control requirements quickly enough on a constant basis.
ECS/ProcessExpert is able to continuously monitor, assess and fine-tune each process, enabling it to achieve control targets and maximise process performance across the entire plant.
ESC/ProcessExpert also enables a minerals plant to develop a uniform operation strategy that outlines the best way to run the plant. Once this strategy has been established, training new operators becomes much easier.

Impactmeter
The Impactmeter is an innovative example of how FLSmidth uses dedicated technology to further enhance process performance and extend the operational life of grinding mills. Through specially designed acoustic sensors and proprietary software load induced impacts generated inside SAG mills are monitored and interpreted so that undesirable impacts caused by steel balls striking the mill liners are eliminated.
Integration of the signals provided by the Impactmeter to ECS/ProcessExpert allows the advanced process control system to make appropriate adjustments to mill operational conditions that improve ore reduction and improve energy efficiency. At the same time the elimination of ball on liner impacts helps to prolong liner life and extend production between mill relining campaigns, further adding to mill availability and reduced operational costs.
