Three ways to improve your crushing circuit for

There are a couple of steps to optimizing a crushing circuit- firstly to optimize machine performance, and secondly to optimize the overall performance of your circuit. Optimizing a machine involves verifying all aspects of your equipment to maximize process and mechanical performance. The crusher's chamber is a good place to start. Over the life of a mine, the production goals of a single

An Improved Control Strategy for Ball Mill

17.09.2010· Abstract. An improved control strategy is proposed to control ball mill grinding circuits for energy saving and pollution reduction. A two-layer optimization architecture combined by particle size optimization layer and energy optimization layer is developed, where the optimal particle size set-point is calculated first, followed by the energy optimization step.

Abstract: Anglo Platinum's control schema for crusher circuits follows a layered approach that includes basic control (regulatory, interlock and sequence control), fuzzy logic, rule-based and model predictive control. This allows for a robust approach to circuit optimization. This paper outlines a typical control schema for a crushing plant, and discusses the benefits that have been achieved

Grinding control strategy on the conventional milling

The aim of the control strategy is to minimize particle size to flotation for a certain ore feed rate, or alternatively to maximize ore feed rate for a specific required particle size. The control strategy is shown in Figure 1. The main parameter influencing particle size from the circuit is ore feed rate.

Closed-loop System and Closed-loop Control

Closed-loop control systems are also called "feedback control systems" are very common in process control and electronic control systems. Feedback systems have part of their output signal "fed back" to the input for comparison with the desired set point condition. The type of feedback signal can result either in positive feedback or negative feedback.
