What is the name of sand made by stone?
Some people call it artificial sand and others call it machine-made sand. In recent two years, with the shortage of natural sand resources, in order to better meet the market demand for sand, it has become a common trend to use professional sand making machines to process stones into machine-made sand.
The sand made by stone refers to the use of some minerals such as granite and river pebbles as raw materials.First, large stones are processed into small stones through crushing equipment, and then processed into coarse sand, medium sand, fine sand and ultra-fine sand required for construction, road construction and water conservancy projects through sand making equipment. In order to avoid damage to the natural ecological environment caused by excessive exploitation of river sand and protect the existing river sand resources, the state strictly investigates the phenomenon of excessive exploitation of river sand, so the use of machine-made sand is more and more frequent!
1.What is the difference between sand made by stone and river sand?
01. Different formation conditions.Machine made sand is the sand produced by machine crushing and sand making, and river sand is formed by natural scouring and sedimentation.
02. Different stock supply.River sand belongs to non renewable energy. Due to years of exploitation, the reserves of river sand are less and less, the supply is in short supply and the price is soaring; The raw materials for the production of manufactured sand are sufficient. River pebbles, pebbles, granite, construction waste, gravel tailings and stone slag can be used as the raw materials for the production of manufactured sand.
03. Different material characteristics.Material characteristics mainly refer to the firmness and durability of stone materials. The firmness of machine-made sand is worse than that of river sand, but it can still meet the excellent product index of national use standard, and there is no problem in ordinary concrete. If the concrete quality requirements are high, admixtures can be added to machine-made sand, and the crushing index and stone powder content of concrete can be controlled at the same time.
04. Different prices.Although the prices of stone crushed sand and river sand are different everywhere, basically, machine-made sand is cheaper than river sand. Compared with river sand, machine-made sand will be about 20 yuan cheaper per ton.
Which is better, machine-made sand or river sand?If single from strong and durable, river sand quality is better, but river sand resources are scarce, the price is high, the other standing on sustainable environmental protection policy, your boss is advised to consider the stone made of sand, the sand materials, low prices, and the key raw material control, the discharging granularity namely modulus can be adjusted, the finished product is ribbed body, is advantageous for the cement, additives of adhesive, It improves the strength of concrete, so there are indications that stone sand is better than river sand.
2.What equipment is needed to break stone into sand?
01. Crushing equipment.Jaw crusher is usually used for primary crushing. The feed inlet of jaw crusher is large and can crush large stones, which can be used in almost every sand and stone production line;For secondary crushing, we can select equipment according to the hardness of the broken stone. The cone crusher is suitable for materials with high hardness and large production capacity, which is suitable for large sand and stone production lines; The impact crusher is suitable for materials with low hardness and good particle size of finished products. It is suitable for buildings and building materials with strict requirements for sand and gravel aggregate. They crush the material below 50mm for sand making.
02. Sand making equipment.It is recommended to select VSI sand making machine, which is an upgraded version of the traditional sand making machine. The single machine output can reach 50-650t / h, and has the effects of sand making and shaping. The fine sand and gravel processed by it has uniform particle size and high grading, and can meet the requirements of sand use in various fields of the market. In addition, it is also environmentally friendly, can easily realize dust-free operation, and help users easily pass the EIA!
03. Sand washing equipment.Users who have requirements on the cleanliness of finished sand can configure a sand washer, which can clean the stone powder, dust and other impurities covered on the sand surface, effectively improve the quality and cleanliness of finished sand, with better quality and higher price.The above is the core equipment used in the production of stone into sand. In addition, it also needs auxiliary equipment such as vibrating feeder, vibrating screen and conveyor. What kind of equipment and model to choose depends on your actual needs.
