Artificial sand is the main major raw materials of construction projects and variety of water control projects.With the natural sand and gravel decreased gradually, we have adopted relative policies to limit the development of construction industry.Thus, the sand making machinery could improve the development of sand making production line.
In China, the sand and gravel used in construction generally uses the natural sand and gravel, such as sand from river, sea and mountain, etc. In recent years, along with the improving of people's environmental consciousness, the exploitation of natural sand and gravel is limited. Thus, the sand making technology of mechanism sand taking stone as raw material emerge as the times require. Mixing sand refers to the sand made by the mixture of mechanism sand and natural sand.
The so called artificial sand is mechanism sand, which refers to the rock particles with a particle diameter less than 4.75mm which is made by raw material after soil removing treatment and mechanical crushing and screening. However, it does not contain the particles of soft rock and weathered rock. The specifications of sand can be classified into coarse, medium and fine three kind according to the fineness modulus ( indicator characterizing the diameter thickness and category of natural sand ). The bigger the fineness modulus of sand, the more coarse of the sand. The fineness modulus of ordinary concrete used sand is in the range of 3.7-1.6, the medium sand is the most appropriate or add a small amount of fine sand to the coarse sand and the ratio of 4:1.
The building used sand and gravel is different according to the different construction of sand gravel requirements. Sand and gravel equipments mainly include impact crusher,according to different fineness requirements of the material and the different scales of the construction. Along with the scale of the building is more and more high, the aggregate production scale also increase, which can promote the continually technology development of the gravel equipment. Henan Hongxing new sand making machine is the successfully developed of professional sand making equipments used in construction. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like vibrating screen, Henan Hongxing is always doing the best in products and service.
Henan Hongxing technical staff combined the sound-thumbs of the experts in crushing industry designed out the new artificial sand processing equipment with modern technology and high dynamic economic index, which ensures the project required aggregate gradation and can ensure the dynamic balance of produce supply during the period of the construction project. It is also the fundamental purpose of artificial sand and gravel processing plant.
The industry development could provide huge potential improvement opportunities for different crushing and screening equipments.These types and models could adapt the different needs of different levels.It could meet the need of sand making machine development generally.
