Grinding is a significant and critical part of the ore winning process. On average, milling is the process that requires the most energy in the whole mining operation. To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of lowgrade ...

In control systems, safety is (or at least should be) an important design priority. If there are multiple ways in which a digital control circuit can be designed to perform a task, and one of those ways happens to hold certain advantages in safety over the others, then that design is the better one to choose.

This reduces grinding energy and results in increasing product throughput. These grinding aids are added to the cement prior to the final grinding circuit. For controlling the grinding aid to the circuit, the customer was using individual diaphragm pumps and was not satisfied due to inconsistent dosage control and pump unreliability.

Reliable control of grinding circuits is critical to more efficient operation of concentrator plants. In many cases, operators still play a key role in the supervisory control of grinding circuits but are not always able to act timely to deal with disturbances, such as changes in the mill feed. Reliable process monitoring can play a major role in assisting operators to take more timely and ...

Many plants with advanced process control are either too constrained or have the turned off as the ore parameters have drifted outside the control constraints. As a result, most grinding circuits are operated sub optimally and inconsistently with the full potential of the asset underutilised and inefficient.

Sep 13, 2019 · The comparison show that it is possible to control the grinding circuit using reinforcement learning. In addition, contrasting reinforcement learning from the existing PID control, the algorithm is able to maximize an abstract control goal: maximizing profit as defined by a profit function given by our industrial collaborator.

Furthermore, well instrumented and performing base level automation in the grinding circuit enables advanced process control () strategies that utilize measurements from the whole circuit to stabilize and optimize production. In this paper alternatives for incorporating process measurements and controls to typical grinding circuits are proposed.

Grinding circuits can exhibit strong nonlinear behaviour, which may make automatic supervisory control difficult and, as a result, operators still play an important role in the control of many of these circuits. Since the experience among operators may be highly variable, control of grinding circuits may not be optimal and could benefit from automated decision support.
