Reasons for the price increase of machine-made sand
Sand is one of the necessary building materials in construction. With the development of urbanization, the mining volume of river sand has been very large. Stocks of river sand have been declining. After the shortage of river sand, the ecological environment of the river and the safety of the river are also greatly affected. At present, river sand mining is restricted in many areas.
So machine-made sand appeared. Machine-made sand is mainly obtained by crushing large stones such as natural sand and gravel to obtain a fineness close to that of natural river sand. The machine-made sand processed by machine-made sand equipment is superior to natural river sand in terms of physical properties.
The industry has generally regarded machine-made sand as a substitute for river sand, and has obvious advantages. The production of machine-made sand is also very easy. The main equipment is sand making machine and sand washing machine. As long as there are stones, it can be produced and processed. With the reduction of river sand resources, the demand for machine-made sand is gradually increasing, which causes the price of machine-made sand to rise all the way.
