How sand is made Materials with particles from 025 in (64 mm) up to about 60 in (152 cm) are classified as coarse aggregat Sand has a density of 2,600-3,100 lb per cubic yard (1,538-1,842 kg per cubic meter) The trapped water content between the sand particles can cause the density to vary substantially The Manufacturing Process...
Steel manufacture The basic raw material for steel manufacture is either the hot metal from the blast furnace, steel scrap or a mixture of both The proportions of material used vary according to the process and the type of steel required Steel can be described in general terms as iron with most of the carbon removed, to make it tougher and more ductile There ....
Steel Slag In the basic oxygen process, hot liquid blast furnace metal, scrap, and fluxes, which consist of lime (CaO) and dolomitic lime (CaOMgO or "dolime"), are charged to a converter (furnace) A lance is lowered into the converter and high-pressure oxygen is injected , This is the major source of steel slag aggregate After being tapped from the ....
Recycled Aggregates Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling [A method of separating solid particles according to size alone is called screening]...
How grinding wheel is made One important aspect of a grinding wheel that can be created or altered through additives is porosity, which also contributes to the cutting characteristics of the grinding wheel Porosity refers to the open spaces within the bond that allow room for small chips of metal and abrasive generated during the grinding process...
Construction aggregate aggregate physical properties, and, in particular, gradation (size control) Establishing a stable production process may reduce variability of the product EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits...
Manufactured sand production One of the key benefits of sand produced with a process is the precise control of the continuous grading This process requires deep integration and automation between different crushing and separation stag Screens do the work when oversize aggregate fractions exist by returning these fractions back to the crushers...
