Energy considerations in compressive and impact crushing

Aug 01, 2008· But in a mine, the cost and energy consumption associated with fine grinding are considerably larger than those associated with the compressive crushing. This difference in cost and energy consumption has essentially two explanations. As the particle size is reduced, the specific surface area increases.

Strength and stiffness of compacted crushed concrete

Dec 01, 2013· The strength and stiffness of CCA with a maximum particle size D max =37.5 mm obtained from a typical concrete crushing plant are noticeably lower than CCA sieved to D max =19 mm compacted using the same energy. However, when compacted to the same dry density, the original CCA exhibits the strength and stiffness higher than the sieved CCA.

Energy and Cost Analysis of Cement Production Using the

The study evaluates the energy consumption of both wet and dry processes cement manufacturing plant in Nigeria. En- ergy consumption data collected for the period 2003 to 2011 were used to estimate the energy consumption of the crushing, milling, agitation, burning, grinding and bagging operations. The total energy evaluation was based on the

Environmental impact of concrete Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

The energy required to produce materials: constraints on

For example, sustainability guidelines for energy and carbon emissions suggest that we need to halve our energy use from 2000 to 2050.1 At the same time, to allow developing countries to ‘catch up’ to the developed world, we would need to allow for a doubling of demand [5,8,9]. Taken together, this would require that the energy intensity of
