As a high-quality machine-made sand and gravel raw material, granite has higher hardness and greater wear and tear on equipment. It is recommended to use the four-stage crushing of "jaw crusher + single-cylinder hydraulic cone crusher + multi-cylinder hydraulic cone crusher + vertical shaft impact crusher" mode, sharing the crushing pressure of each section, ensuring the output of the production line, and the cost of later operation and maintenance will also be greatly reduced.


Jaw crusher - coarse crushing - crush large rocks mined from the mountain to medium size (discharge 5-30cm)

Cone crusher - medium and fine crushing - the combination of single-cylinder and multi-cylinder cone crushers can share the crushing and wear pressure, have higher crushing efficiency and greater output, suitable for medium and large hard rock crushing projects

Vertical shaft impact crusher - Shaping & Fine Crushing - On the one hand, it is used for shaping stones, removing the sharp corners of the stones, making the grain shape rounded, and meeting the high standard stone standards used in key projects such as high-grade highways and railways; on the other hand, it crushes stones and stone powder. , the leftover materials are further crushed into machine-made sand below 5mm to meet the production requirements of the production line with sand and gravel coming out at the same time.

In addition to the main crusher, a complete granite sand and gravel aggregate production line also includes supporting equipment such as vibrating feeders, circular vibrating screens, and belt conveyors. It undertakes functions such as raw material transportation and finished product screening, and jointly completes the production of sand and gravel.

The above are the required equipment for a complete granite crushing production line. If you have any equipment needs, you can contact us at any time. Huayi Engineering will serve you wholeheartedly!
