The Comprehensive Guide to Skid Crusher Material Below 20mm Size in Crushing and Sand-Making Industry
The global construction and infrastructure sectors heavily rely on high-quality aggregates, with demand for precisely graded materials like skid crusher output below 20mm growing rapidly. This size range is critical for concrete production, road bases, and asphalt mixes. Modern crushing and sand-making plants prioritize efficiency, particle shape, and gradation control to meet stringent industry standards.
1. Primary Crushing: Jaw or gyratory crushers reduce raw materials (e.g., granite, basalt) to <200mm.
2. Secondary/Tertiary Crushing: Cone or impact crushers further process material to ≤20mm. Skid-mounted crushers (mobile or stationary) excel here due to compact design and quick setup.
3. Screening: Vibrating screens segregate output into 0–5mm, 5–10mm, and 10–20mm fractions for tailored applications.
4. Sand-Making: VSI crushers enhance cubical particle shape for premium concrete sand (0–5mm).
Key Equipment for ≤20mm Production:
Q1: How to minimize over-crushing (<5mm fines) when targeting 10–20mm output?
A: Adjust crusher settings (e.g., CSS on cone crushers) and use multi-deck screens for precise separation.
Q2: Can skid-mounted plants replace traditional stationary setups?
A: Yes, for medium-scale projects. Skid systems offer mobility but may have lower throughput than fixed plants.
Q3: Which rocks are unsuitable for ≤20mm production?
A: Highly abrasive or sticky materials (e.g., clay-rich limestone) may cause wear or clogging.
