Calculating Stockpile Capacity

08/04/2018This results in very long conveyors and supports and accompanying large foundations to withstand the loads on the conveyor. More importantly, because the conical pile occupies such a small ground area in relation to its volume, soil pressures on large piles can exceed the bearing strength of the local soil. For example, if 1600 kg/m (100 lb/ ft) material is being stockpiled on soil with an

Steel Production

Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed. The cooked coal, called coke, is removed from

Formation mechanism and applications of cenospheres: a

07/01/2020Cenospheres being tiny spherical particles act as mini ball bearings in concrete mixture. Due to ball-bearing effect, adding cenospheres in conventional concrete mixture will enhance workability if the dosage is between 1 and 5%. Ultra-fineness of cenospheres can also enrich finishability and trowelability of concrete. Moreover, cenosphere also has a positive influence on concrete strength and

Economic Growth

The calculation of real and nominal economic growth can be shown using an example of an economy that only produces one good - let's say it is apples. Suppose that in year 1, the volume of apples produced was 100kg and the price of apples was $2 per kg, so the total value of production was $200 (100 x $2). In year 2, 104kg of apples were produced and the price was $2.05 per kg, so the total
