technical field

The utility model relates to the technical field of gravel sand making, in particular to a stone crushing sand making device.

Background technique

It is an indisputable fact that in today's society, the success of machine-made sand is used. A large number of engineering practices such as the Three Gorges Water Conservancy Project have fully proved it, thus confirming the necessity and possibility of machine-made sand.
