Artificial sand & natural river sand
Sand is widely used in highway construction, concrete making, etc. As the field of industry application gradually expanded, the gradual application of natural sand work more and failed to keep pace with the various sectors of modern world development needs. For the most part, machine-made sand is produced to meet the great needs. Here you can learn more about definition of machine-made sand and its wide applications.
According to the definition of machine-made sand, sand is kind of rock particles with diameter less than 4.75mm after removing dirt, crushed and screened while soft rock and weathered rock are not included. Sand specifications: according to fineness modulus (Mx), sand specification is divided into coarse, medium and thin. And among this, fineness modulus of coarse sand is 3.7-3.1, and the medium sand is 3.3-3.0, and the thin sand’s fineness modulus is 2.2-1.6.
Sand rock: There are many kinds of rocks used to make sand. Generally there are Granite, Basalt, Natural river pebbles, Andesite, Rhyolite, Diabase, Diorite, Sandstone and Limestone, etc. The sand produced is of different intensity and purposes according to the rocks’ kinds.
Advanced sand making equipments
VSI5X Crusher becomes the core equipment in sand making business. It adopts Germanic advanced technique and owns a number of patents and independent intellectual property rights. VSI5x series VSI crusher is highly recommended to crush high hardness materials as iron ore, nonferrous metals, corundum, and bauxite, quartz sand, basalt, etc.
Sand prices began to rise year after year, due to the lack of natural sand. In order to deal with the problem that the shortage of the construction sand between production and consumption, then artificial sand was produced.
sand is also called manufactured sand, which was produced by crush the cobble stone or other stone into sand by sand making machine. As the basic materials of concrete, cement mortar of architectural sand, Successful application of artificial sand is an indisputable fact that a large number of engineering practices (including the Three Gorges Project) has demonstrated the possibility and necessity of using sand.
There is scarcity of natural sand due to heavy demand in growing construction activities which forces to find the suitable substitute. The cheapest and the easiest way of getting substitute for natural sand is by crushing natural stone to get artificial sand of desired size and grade which would be free from all impurities.
with shortage of quality sand for construction will need the artificial sand. The distance and the fact that the vehicles are overloaded to make it profitable for operators puts a premium on sand availability.
advantage of using good river sand is that it mixes easily with concrete and bonds well, making the plastering work less cumbersome for the masons and giving a good finish to the buildings. But on the other hand, the continuous mining of sand causes environmental problems.
In such a scenario, artificial sand is seen as a welcome alternative to natural sand. Joyal has hit upon the idea of designing a kind of sand making machine in order to making sands from many kinds of stones. The artificial sand would be available in two grades — 1-3 mm for plastering and 3-5 mm for all construction work. As it would be double-washed and silt-free, it would bond better with concrete and would require lesser curing time than river sand.
When the input size of your materials is smaller than 40mm,we recommend you the sand making flow equipped with vsi5x series sand making machine ,vibrating screen, sand washing machine, etc; otherwise, we have another solution designed for you,This flow is equipped with vibrating feeder, jaw crusher, impact crusher (optional ), cone crusher, vsi5x series sand making machine,vibrating screen and sand washing machine. According to different process requirements, various types of equipment can be combined to meet the technological requirements of different customers.
High strength pumping concrete made by artificial sand will not block the pump in the process of pumping. The concrete of right use of artificial sand has large density, impermeability, good freezing-resisting property, other physical properties and long-term durability can use to meet the design requirement too.
Artifical sand is particularly suitable for the preparation of high strength concrete, high-performance concrete and pumping concrete.
