How can we optimize the quality of sand in a large-scale sand-making system?

According to relevant information, in 2019, the National Development and Reform Commission, the Ministry of Natural Resources and other ten departments jointly issued several opinions on promoting the high-quality development of the mechanism sandstone industry. This opinion focuses on the planning and establishment of the development of the mechanism sandstone. The goal is to plan to form a perfect and reasonable mechanism sand supply system by 2025, and train multiple enterprises to develop intelligently, efficiently, greenly and with high quality. In early 2020, in order to implement this opinion in various regions, various provinces and cities have successively introduced local implementation policies. For example, Changsha City surveyed and evaluated the quality of the city's sandstone mines, selected sandstone sites, etc. The foundation of the project of mechanical sand and stone has been laid, and the era of development is ushered in. So, in a large-scale sand-making system, how to optimize the quality of sand and gravel?

Because the large-scale sand-making system can bring high-yield finished sand, but while we increase the output, the quality must be optimized, and both quality control and output indicators are indispensable. So far, the sand making process can be divided into two types, dry and wet. Both have their advantages. Regardless of the choice of any one of the sand making processes, the quality of the sand and stone must not be reduced. The solid-liquid separation system in the wet process and the dust removal and powder removal system in the dry process. All are designed to remove excess fine powder and sediment contained in machine sand. The solid-liquid separation system can separate wastewater into clean water and reuse it. The dust removal and de-dusting system can collect dust in a centralized manner. Both must follow the green and efficient development goals. .

Generally, the processing stage of medium crushing will contain a large number of pin pieces, uneven grain shape, and high fineness modulus. If a screening process is added to the medium and fine crushing stage in the machined sand production line, the sieved material The quality of the finished sand will be significantly improved when it is put into the shaping sand making machine. In the machine-made sand production line, not only the main engine and auxiliary equipment need to cooperate with each other, but also the help of the sand washing and dust collection system can better optimize the quality of the finished sand and promote the establishment of the sand and gravel supply system.
