Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving.
In China, the artificial sand was mainly used in the construction of hydropower systems. For example, the Three Gorges Project and the Yellow River Xiaolangdi Project used artificial sand to prepare concrete. Due to the remote environment of the hydropower project and the high quality of sand and gravel, the projects have taken the materials locally.
Many Indian states have decreed the use of crushed sand in infrastructure construction because of its high compressive strength and cohesion and the adverse environmental effects of river sand mining, which will greatly boost the demand for artificial sand.
There are both natural and human factors in the increasing demand for artificial sand. The former is that the natural sand is about to run out, while human factors include people's requirements for environmental protection and the need for high-quality concrete.
With the development of infrastructure, the natural sand resources formed by hundreds of thousands of years in many countries and regions have been almost exhausted, which has affected the further development of construction projects.
Driven by huge interests, natural sand has been indiscriminately mining, which changes the river course, affects the safety of river embankments, destroys the living environment of fish and contaminates the groundwater. The crushed stone sand is an important alternative resource to change this phenomenon.
In the process of mining river sand, it often produces a large amount of tailings which is not used reasonably. Especially in small mines, the tailings are piled up at random, occupying land and polluting the environment.
Besides, in urban planning and construction, a large amount of construction waste is generated, which actually can be crushed by the crushers to produce the artificial sand and aggregates for promoting resource utilization.
With the rapid development of concrete technology, the comprehensive performance of high-performance concrete and high-strength structural concrete has higher requirements on the quality of aggregates, requiring it with stable quality, good gradation and shape, while less and less natural sand meets the requirements. Therefore, people are turning their focus on artificial sand.
Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete strength grade is below C60. When meeting the corresponding technical requirements, they can also be used for concrete projects such as ports and water conservancy.
The vibrating feeder feeds the stone evenly into the coarse crushing machines for the primary crushing of the stone. The crushed stone from the coarse crushing equipment is transported through the belt conveyor to the fine crushing machines for the secondary crushing.
The primary crushing equipment directly processes supplied materials from the stone material factory and is the foremost processing plant. The jaw crusher is the ideal choice for primary crushing.
The secondary crushing equipment is responsible for the middle and fine crushing in the stone crushing process. The secondary crushing equipment mainly includes impact crushers and cone crushers.
The crushed material is conveyed by the belt conveyor to the crushed sand making machine for fine crushing. The finely crushed material is then screened through the vibrating screen for coarse sand, medium sand, fine sand and other specifications.
VSI sand making machine is called high cost-effective sand making equipment with low initial investment cost and good use effect. It is high in operation efficiency with the PLST crushing cavity.
The HVI sand making machine manufactured by Fote is more advanced in technology. Its butt ends and lubrication scheme are modular in design, and the peripheral guard plate can be turned up and down to extend its life cycle. It has the effects of sand making and shaping at the same time.
For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the sand manufacturing machine, and the sewage discharged from the sand washing machine can be recycled by the fine sand recovery plant.
The following video shows clearly the difference between crushed sand and river sand from the aspects of source, wastage, setting time, shape, silt content and so on. It is worth collecting and sharing with friends.
The table below shows the mix ratio of M15 M55 and M55 M55 concrete designed for artificial sand and river sand. The results show that in the same Concrete Mix Design, the strength of concrete by artificial sand is higher.
As the demand for aggregates from China, Africa, Latin America, Europe,etc. will continue to rise, and the price of artificial sand will also increase, the outlook for the global aggregate market for sand and gravel is worth looking forward to.
According to the Global Sandstone Aggregate report, by 2020, the demand for aggregates of sand and gravel in the Asia-Pacific region will increase the fastest in the world, and the growth rate of India, Vietnam, Malaysia, Indonesia and other regions will be among the best.
Due to the economic transformation, the demand for sand and gravel aggregates in China will slow down. However, the report predicts that by 2020, China will still be the world's largest aggregate demander, accounting for almost half of the world's total aggregate.
The Global Sandstone Aggregate report shows that the reserves of natural sand are gradually decreasing globally, and in some developing countries where the demand for aggregates and sand is huge, illegal sand mining has happened frequently. According to the report, by 2020, the reserves of natural sand resources in some countries will be quickly depleted.
The depletion of natural sand resources will lead to a sharp increase in the price of aggregates and artificial sand, especially in areas where the demand for aggregates is huge. It can be seen that the profit margin of the artificial sand is very large.
The m sand manufacturing machine produced by the supplier Fote is suitable for m sand making production line of high hard and abrasion-resistant materials such as limestone, quartz stone, granite, river pebble, basalt, cement, various ores, glass raw materials, mechanism building stone, gold slag, etc.
The limestone, widely distributed in nature, is easy to obtain. It is the main raw material for manufacturing cement, lime and calcium carbide. After being processed, limestone is used in large quantities as building materials. Generally, simple processing process is through the limestone sand production line.
Quartz is a hard, wear-resistant, chemically stable silicate mineral mainly composed of silicon dioxide. It is an important industrial mineral raw material generally used in glass, building materials, ceramics, high-tech electronics industry, etc. after crushing and sand making.
The granite has the characteristics of hard texture, high strength, abrasion resistance and weathering resistance. It has the title of "The King of Rocks" and is a good building material. It is rich in resources with low mining costs but high product value. Granite is a popular choice when the product needs to be weather-resistant or durable.
The river pebble resources are rich with low collection costs and high application value. After making sand from river pebble, it is widely used in water conservancy and hydropower, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering and high-rise buildings in the engineering field.
Basalt is the best material used for repairing roads, railways and airport runways. With the characteristics of strong compressive resistance, low crushing value and strong corrosion-resistance, it is the best cornerstone for the development of railway transport and road transport.
