How to Select Suitable Crushing Equipment Based on Ore Raw Materials? As fundamental materials for engineering construction, sand and gravel aggregates commonly utilize raw materials such as pebbles, granite, diabase, basalt, limestone, and others. The selection of crushing equipment varies depending on the specific raw material.

During processing, appropriate equipment should be selected based on the specific raw material characteristics.

First, when classifying raw materials, they can generally be divided into hard rock and soft rock.

Hard rock is primarily represented by pebbles, granite, and basalt, with hardness typically exceeding 150 MPa. When processing these materials, jaw crushers and cone crushers are typically selected. Depending on the finished product requirements, impact crushers (shaping machines) may be used in conjunction to eliminate needle-like fragments and internal cracks generated during crushing. Finally, vibrating screens are employed for sorting, separating the crushed stone into finished sand and aggregate of various specifications.

Second, when processing soft stone materials like limestone or sandstone with hardness below 150 MPa, crushing equipment options include jaw crushers, impact crushers, and heavy hammer crushers. Similarly, impact crushers (shaping machines) can be integrated based on finished product requirements. This approach eliminates needle-like fragments and internal cracks while effectively boosting manufactured sand output. Typically, a manufactured sand rate of around 60% can be achieved.

One crucial point to note here is that limestone exhibits significant hardness variations depending on its silica content. We must pay close attention when assessing stone hardness. For limestone with very high silica content, cone crushers are required for crushing.

The selection of sand and gravel aggregate processing equipment and process flow design involves multiple approaches. Specific choices and combinations must be determined by comprehensively considering various factors such as raw material hardness, bulk density, clay content, and finished product requirements.
