Optimal energy management for a jaw crushing process in deep mines
This paper develops two optimal control techniques for the TOU based-optimal energy management of a jaw crushing station in deep mines under both physical and operating constraints. The first technique is referred to as a variable load (VL)-based optimal control, while the second one is an optimal switching control.

What Is The Crushing Process
Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

Optimal energy management for a jaw crushing process in deep mines
Abstract. This paper develops two optimal control models for the energy management of a mining crushing process based on jaw crushers. The performance index for both models is defined as the energy cost to be minimized by accounting for the time-of-use electricity tariff. The first model is referred to as a variable load-based optimal …
