Aggregate crushing equipment and coarse and fine aggregate crushing plant
For coarse aggregate crushing and grinding of all, we advise you to choose jaw crusher SBM. Equipment jaw crusher is the most popular global crushing. Its structure is simple, but the actual work is high. In addition, it is easier to change the verification and wear or routine maintenance.
Aggregate Crushing
For other aggregates of correction, we recommend you choose MTW Trapezium Grinding Mill European. It has improved the MTM trapezium mill. Both plants have been put forward that the traditional ball mill. You can choose these mills all equipment.
Coarse and Fine Aggregate Global Presentation
Aggregate refers to granular materials in the concrete filled the role of the skeleton. This is usually called concrete aggregate diameter is generally greater than 0.16mm. According to the bulk density, aggregate is usually divided into three types that are aggregated in general, and light overall weight aggregates (such as barite). In addition, aggregates can be divided into fine and coarse aggregate total by the aggregate size.
Coarse aggregate includes pebbles, gravel, crushed gravel, slag, broken bricks, the second aggregate (crushed concrete objects), and various natural rocks (such as andesite, quartzite) or artificial materials calcined (such as bricks blocks, clay clinker) with special features, etc..
Aggregate refers to the end gravel or crushed stone on which the stone is less than 5 mm used in the preparation of concrete. Fine aggregate is also divided into coarse sand, medium sand, fine sand and finer sand, the fineness modulus is 3.7 ~ 3.1, 3.0 ~ 2.3, 2.2 ~ 1. 6 ~ 0.7 and 1.5. According to sources of production and materials, fine aggregate can be divided into ordinary river sand, mountain sand, sea sand, artificial crushed sand (stone chips), and the waste of sand.
Concrete aggregate commonly used to clean river sand, suitable for medium and coarse sand. Coarse aggregate should properly use gravel, crushed stone or crushed gravel depending on local resources and physical conditions of supply, combined with engineering and technical requirements. The maximum size of coarse aggregate should be decided according to the spacing of steel structures and construction methods, equipment and other selected conditions.
Alkaline activity test should be taken on the aggregate used in concrete in conditions of water, soil, open or wet. Yards should adopt comprehensive local metal construction should pay attention to the use of metallurgical slag, to shorten the distance and reduce shipping costs, resource development and the benefits of waste damage.
