The general process flow of sand and gravel crushing production line includes: feeding, crushing (stone crushing), sand making (fine sand), screening, conveying, etc. Moreover, the process flow of the production line is of great benefit to optimizing equipment configuration and saving capital investment. The main process is as follows:

Crushed stone production line

Fragmentation stage

Special coarse crushing equipment, medium and fine crushing equipment can be selected. The specific crusher needs to be selected based on the hardness of the ore. For the sand with high hardness, it is recommended to choose the extrusion type crushing equipment (jaw crusher, cone crusher) Etc.), for brittle or medium-hard sands, it is recommended to choose impact crushing equipment (hammer crusher, impact crusher, etc.), which only differ in working principle.

Sand making stage

According to the user’s demand for finished product specifications and market trends, after the introduction of crushing, a sand making machine can be configured to further process the non-fine sand and gravel to produce machine-made sand that is more in line with industry requirements to enrich the types of finished products and the market. market.

Application of auxiliary equipment: feeder, screening machine, conveyor, sand washing machine, etc.
