Changing the Energy Consumption The energy consumed can change in three ways. First, if the feed size to the primary crusher is decreased, less energy will be required to crush the ore to the same product size. Second, a decrease in Wi related to additional macrofracturing and microfracturing within individual fragments.
To reduce the energy intensity of this process the experimental model Vibrating-Rotor Crusher [7,9,10] has been developed, in which the combination of grinding methods (impact and cutting) makes ...
An energy benchmarking and bandwidth analysis for the US mining industry [11] showed that the practical minimum energy consumption was about 0.61 billion GJ/year whereas the energy consumption was 1.31 billion GJ/year in 2006. The bandwidth analysis estimates the minimum energy consumption of total mining industries …

Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
Total energy consumption values of primary, secondary, and both crushers were calculated by using these correlations and compared with energy consumption …

1.2.. Production challenges in miningIn a typical mining application, a primary crusher reduces the size of blasted rock; from several hundred mm down to 0–250. mm.. A secondary crusher then reduces the size from those 250 mm down to about 0–70 mm, and is then followed by a tertiary crusher in closed circuit with a screen.The final screen …
1. Introduction. The high energy consumption of crushing is one of the main motivations to study the comminution of minerals. Tromans [1] listed several examples of energy consumption per country, showing that the energy spent in comminution constituted 1–16.7% of the total energy consumed by the industry. The exact value …
Some 37% of the global energy consumption is consumed by industries, and projections indicate an average annual growth of 1.4% in the energy consumption by the industries for the next 25 years (U.S Energy Information Administration, 2009). The mining industry is the second-largest consumer of energy in the world, as compared to other …

The Bond (1952) equation is used to scale the energy consumption in crushing. But the energy required to crush a ton of material differs from machine to machine. As an alternative, Bond's work index can be related to the values that represent energy consumption in industrial crushers by some scaling factor.
