As we can see from the production site, the arrayed equipment successively produced numerous finished gravels and then the finished material was sent into the cement production projects, which had lower production costs compared with purchasing material and had quality finished cement compared with fine gravel material.
The finished stones of sand production can directly be used in cement production, short time finished gravel transportation can hugely reduce part of production costs and improve finial interest, also the remained gravel material can be used into other projects.
