In the long term, archives of size trends of crusher feed and product as related to other key performance indicators such as blast fragmentation, crusher/mill throughput, crusher reduction ratios, Bond Work Index, energy consumption and efficiency expose management level optimisation decisions.
This paper examines the role blasting plays in optimum crushing and grinding with the emphasis on energy reduction. The role of different blasting energy input on fragmentation is studied, and related to needs at the plant. The effect of different feed sizes on energy consumption in crushing and grinding is studied.
The main objective of this paper was to investigate how the approaching of the crushing surfaces involved in the compressive crushing affects the required amount of energy and how the wear of the crushing surfaces correlates with the measured energy consumption. The study concentrates on the geometry and movement of a jaw …

This paper presents a different approach to determine the energy consumption during comminution. The energy required for crushing rocks was obtained by direct measurement of crusher's …
The crusher parameters that affect energy consumption were also identified. A case study of an operating dolomite mine was performed. The results indicated that by changing the burden, spacing and crusher closed-side setting, the overall (blasting and crushing) costs could be reduced by 4.7% to 7.9% annually.
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 control …
Crushing Energy & Work of Crushing Machines.
