A “Black Stone Jaw Crusher” is typically used to crush hard materials like basalt, granite, or other volcanic rocks (often referred to as “black stone” due to their dark color). Below are key details about using a jaw crusher for processing black stone (such as basalt or gabbro):
Features of a Black Stone Jaw Crusher:
1. High Crushing Strength – Designed to handle hard and abrasive materials.
2. Durable Wear Parts – Uses high manganese steel or tungsten carbide jaws for extended lifespan.
3. Adjustable Discharge Size – Allows control over the final crushed product size.
4. Robust Construction – Heavy-duty frame to withstand high-impact crushing.
5. Simple Maintenance – Easy access to wear parts for quick replacement.

Common Applications:
– Mining and quarrying of basalt, granite, or other black stones.
– Aggregate production for construction (roads, concrete, asphalt).
– Recycling demolition waste (if applicable).
Recommended Jaw Crusher Types:
1. PE Series (Primary Crushing) – Coarse crushing with high capacity.
2. PEX Series (Secondary Crushing) – Fine crushing for smaller output sizes.
3. HD German Type Jaw Crusher – Higher efficiency and lower wear.
Key Considerations When Choosing a Crusher:
– Feed Size & Capacity Requirements – Match the crusher’s inlet size with your raw material size.
– Hardness of the Black Stone – Basalt (~6-7 Mohs) requires strong wear-resistant jaws.
– Power Source – Electric or diesel-powered options available.
– Mobility Needs – Stationary plant or mobile jaw crusher (track-mounted/wheeled).
Maintenance Tips:
– Regularly check jaw plates for wear and replace them when necessary.
– Lubricate bearings and moving parts to prevent overheating.
– Ensure proper feed distribution to avoid uneven wear.
