Recently, there have been a series of inquiries from users, such as “Can high hardness rocks be used to process aggregates?”, “What is the process flow for hard rock processing for making aggregates?”, “Are there any real hard rock processing cases?” Today, we will explore these issues.

1，Can high hardness rocks be processed into aggregates?

Can high hardness rocks be used as aggregates? The answer is yes, the hardness of hard rock is even better than that of ordinary stones, so it is definitely not a problem to use as aggregate. However, due to its high processing cost and difficulty, it has been ignored by people until now. However, with the continuous improvement of hard rock processing sand and stone aggregate technology and the increasing abundance of related sand and stone production equipment, it has become increasingly common to process high-quality mechanical sand and stone aggregates in hard rock processing!

2，What is the process flow of hard rock processing for making aggregates?

Hard rock crushing and sand making process flow:
(1) The hard rock is fed into a jaw crusher by a vibrating feeder for coarse crushing, and then conveyed by a conveyor to a cone crusher for further crushing;
(2) The crushed material is screened by a screening machine, and those that meet the feed particle size of the sand making machine are transported to the sand making machine. Those that do not meet the requirements are returned to the cone crusher for further crushing;
(3) The materials coming out of the sand making machine are screened by a vibrating screen, and the sand and stone products that meet the particle size requirements are fed into the material pile by a conveyor. Materials that do not meet the particle size requirements are returned to the sand making machine for further processing.
