According to the current construction condition, gravel aggregate is the most basic and widely used raw material no matter in road and bridge construction or in high-speed highway and railway construction. Building sand is attached much more importance due to material selection and the basic features of sand.

How to choose the reliable sand maker manufacturer becomes the top priority for vast investors. The modern impact sand maker (also known as the third generation sand maker) can not only solve environment pollution issues for mining industry and improve the resource utilization rate but bring huge benefits for fierce gravel field. Adopting machine to produce sand has been used for more than several decades abroad. In China, the research and application of sand maker have also kept more than decade, so the workmanship can meet the basic need of sand making industry.

The crusher machine is transformed in technology. Impact hammer and liner are applied in the inner structure, making the operation more conveniently to realize the two fine crushing types, namely beat and impact. The finished sand is fine in granularity as a result of the application of impact sand maker. There are obvious difference between modern sand maker and traditional sand maker. The traditional sand production process can be realized by crushing rock with jaw crusher firstly. And then the primarily crushed rock will be crushed again with impact crusher according to the rock hardness and output demand. At last, the qualified sand is produced. However, the impact sand maker is easier to finish the whole process and get finer sand.
