Aggregate Grinding Mill Manufacturers
Coarse aggregate involves pebbles, pebbles, crushed gravel, blast furnace slag, broken bricks, the 2nd aggregate (concrete crushing objects), and also many purely natural rocks (such as andesite, quartzite) or artificial calcined supplies (this kind of because brick blocks, refractory clay clinker) with specific capabilities, and so forth.
Fine aggregate refers to this gravel or perhaps crushed stone materials in whose stone size is lower than 5MM applied for setting up the concrete. Fine aggregate is usually divided into coarse sand, approach sand, fine sand also as finer sand, whose fineness modulus is really of three. 7 ~ 3. one, 3. 0 ~ 2. three, two. two ~ one. 6 and in addition one. five ~ 0. 7. In line with production sources and resources, fine aggregate can be divided in to ordinary river sand, mountain sand, sea sand, artificial killed sand (stone chips), and waste sand.
Concrete fine aggregates usually utilizes clean river sand, perfect for your real medium as well as coarse sand. Coarse aggregate should properly use gravel, crushed stone and even crushed gravel based on close by sources at the same time as material supplying problems, combined with engineering and technical specifications. The optimum size of coarse aggregate needs to be decided according to the construction, steel spacing and construction tactics, equipment and also other selected disorders.
