Can mountain stones/ordinary stones be processed into sand and gravel aggregates?

Yes, mountain stones and ordinary stones can be processed into sand and gravel aggregates. This process is called quarrying, which involves extracting stones from mines or quarries, then crushing and screening the stones to produce the required aggregate size.

The process typically begins with drilling and blasting to extract the stones from the quarry. The stones are then transported to a processing plant, where they are crushed and screened to produce different sizes of aggregate, including sand and gravel.

For example, a typical quarrying process might involve the following steps:

1. Drilling and blasting: Holes are drilled into the mountain or quarry, and explosives are placed in the holes to break up the stone.

2. Hauling: The broken-up stones are hauled from the quarry to a processing plant.

3. Crushing: The stones are crushed in a series of crushers, which reduce the size of the stones gradually.

4. Screening: The crushed stones are screened to separate them into different sizes of aggregate, including sand and gravel.

5. Washing: The aggregate is washed to remove dust and other impurities.

6. Sorting: The aggregate is sorted by size and quality to meet the specifications of the customer.

7. Storage: The aggregate is stored in a yard or warehouse, ready for delivery to construction sites.

Overall, the process of quarrying mountain or ordinary stones into sand and gravel aggregates is a complex and resource-intensive process, but it is an essential step in the production of construction materials.
