Gravel, also known as crushed stone, is a rock or ore waste that has been crushed, screened, and treated. Due to its hardness and particle size, gravel is often used as an aggregate or filling material in construction, roads, bridges, and other civil engineering projects. However, in recent years, with the continuous progress of science and technology and the improvement of environmental awareness, the reuse value of stone slag has received more and more attention.
Can gravel be used to make sand?
Sand making is to crush large rocks or ores into sand with a certain particle size range through crushing, screening, grinding and other processes. Sand is widely used in construction, water conservancy, highways, railways and other fields, such as concrete fine aggregates, ground materials, permeable bricks, etc. As far as gravel is concerned, it has undergone a certain degree of crushing and screening, so it has a certain sandiness. However, due to the particle size, hardness and chemical composition of the slag may be different from the special sand making raw materials, sand making equipment is required to adjust and optimize the slag.
What kind of machine is used for gravel sand making?
Through the design of the four-port impeller and the impact angle of the crushing cavity, the impact crusher improves the throughput, large output, smooth discharge, and effectively prevents material blockage and avoids abnormal damage. The finished product is delicate, the grain shape is good, and it takes into account the wear-resistant perimeter guard plate and the rock self-crushing point. The developed low-loss wear-resistant structure reduces wear costs.
