In the construction industry, there are three kinds of sand: natural sand, manufactured sand and mixed sand.
Natural sand: natural sand refers to the rock particles formed under the action of natural conditions with the particle size less than 5mm. It is mainly divided into river sand, sea sand and mountain sand.
Manufactured sand (M-Sand): manufactured sand refers to the rock particles whose particle size is less than 4.75mm after mechanical crushing. It is mainly divided into granite sand, pebble sand, limestone sand, construction waste sand and so on.
Mixed sand: mixed sand refers to the sand material obtained by mixing natural sand and M-Sand in a certain proportion.
Why manufactured Sand is Used?
In recent years, limited by environmental protection and other reasons, the cost of natural sand is higher and higher, and can not meet the growing market demand. In this case, manufactured sand came into being. Through professional equipment, it can be processed into sand of different rules and sizes according to different process requirements, so as to better meet the production demand. At present, manufactured sand is being produced and used in many areas of the country. In some areas, industrial waste, construction waste and waste stone are also processed into recycled aggregate for reuse.
manufactured sand production line
Manufactured sand production line is composed of vibrating feeder, jaw crusher, sand making machine, vibrating screen, belt conveyor and other equipment. According to different process requirements, various types of equipment are combined to meet different process requirements of customers.
Compared with the natural sand, the m sand production line has the advantages of high automation, low operation cost, high crushing rate, energy saving, large output, less pollution and simple maintenance. The manufactured sand produced by the sand production line conforms to the national building sand standard, with uniform particle size, good particle shape and reasonable grading.
