How many mm does the medium sand crush the aggregate?
In civil engineering, aggregates with a particle size larger than 4.75mm are coarse aggregates, also known as "stones"; aggregates with particle sizes between 0.15mm-4.75mm are fine aggregates, also known as "sand" . Sand is generally divided into coarse sand, medium sand and fine sand according to size.
The standard of sand in construction sand: refers to the rock debris formed and accumulated in natural waters such as lakes, seas and rivers with a particle size of less than 5mm, or rock debris accumulated in suitable terrain in the mountains after the weathering of the rock mass.
In recent years, with the increasing shortage of natural sand resources, machine-made sand has become the main source of construction sand.
Machine-made sand is made of stones through crusher, sand making machine, crushing and screening. The performance of the sand making machine has a great influence on the yield and quality of the sand.
The entire SMMVIK sand making system can use limestone, cobblestone, river pebbles, granite and other stones as well as tailings, waste, construction waste, etc. as raw materials, and adopts an environmentally friendly dry process to produce excellent machine-made sand comparable to natural sand. Its fineness modulus and particle size fully meet the standards of concrete sand, and can be used in supporting sand-making projects such as concrete mixing plants, dry-mixed mortars, and cement product factories to meet the huge market demand for high-quality sand.
According to the different requirements for sand particle size in different fields, the SMMVIK sand making system can be adjusted through the discharge port to sort out coarse, medium and fine sands of different specifications to meet the various production needs of customers.
At present, SMMVIK has established thousands of aggregate sand making production lines around the world, transporting a large amount of fine sand and gravel for the construction of roads and bridges, hydropower stations, houses and other projects, and has been widely praised by customers in the industry.
