The Compound Spring Cone Crusher is a spring-hydraulic compound type high-efficiency crushing equipment independently developed by Shandong Hengtai Intelligent Manufacturing. Specially designed for the "more crushing less grinding" mineral processing technology, it serves as the core equipment for secondary crushing (medium crushing) and tertiary crushing (fine crushing) in hard rock processing lines.
Core Positioning: Positioned after primary jaw crusher or gyratory crusher, this Symons-type spring cone crusher handles 80-300mm feed material, outputting 0-50mm fine products for grinding mills or sand making machines. It bridges the primary crushing and grinding/sand making stages, reducing downstream energy consumption by 20-30%.
Process Chain: Jaw Crusher (Primary) → Compound Spring Cone Crusher (Secondary/Tertiary) → Sand Making Machine (Shaping) / Ball Mill (Grinding)

Frequently Asked Questions (FAQ)
Q1: What is the position of compound spring cone crusher in the crushing line?
As secondary crushing (medium crushing) or tertiary crushing (fine crushing) equipment. Typical configuration: Jaw crusher primary crushing (0-200mm) → Spring cone crusher secondary (0-50mm) → Grinding mill or sand making machine. For hard rock, two cone crushers in series: secondary + tertiary.
Q2: What is "more crushing less grinding"? How does this machine achieve it?
"More crushing less grinding" is an energy-saving mineral processing concept—reduce grinding feed size through efficient crushing, thereby reducing grinding power consumption (grinding is 5-10x more energy-intensive than crushing).
This machine achieves it through: Special crushing chamber: Particle bed compression crushing produces fine product 0-25mm High reduction ratio: 8:1 to 15:1, single machine replaces two-stage crushing Result: Ball mill feed size reduced from 25mm to 10mm, grinding power consumption down by 20-30%
Q3: Compound spring type vs full hydraulic cone crusher, how to choose?
Recommendation: For 90% of iron ore, copper ore, limestone projects, compound spring type offers best cost-performance. Choose full hydraulic only for ultra-hard rock (≥350MPa) or fully automated unmanned mines.
Q4: Can impact crusher replace cone crusher for secondary crushing?
For hard rock (granite, basalt, iron ore), cone crusher is better than impact crusher: Cone crusher: Wear parts last 3-5x longer in hard rock Impact crusher: Better for soft rock (limestone) and shaping
Typical configuration: Hard rock → cone crusher secondary; Soft rock → impact crusher secondary.
Q5: How to choose between C-D (coarse) and Z-D (fine) models?
C-D models: Feed 150-300mm, output 25-65mm, for secondary crushing Z-D models: Feed 80-240mm, output 19-50mm, for tertiary crushing or fine secondary
Two C-D in series, or C-D + Z-D combination, can achieve 0-20mm product for high-grade aggregate.
Q6: What is the actual production cost per ton?
Wear parts cost: 0.3-0.8 USD/ton (depending on hardness) Power consumption: 1.5-2.5 kWh/ton Total operating cost: 40-60% lower than jaw+impact combination for hard rock
Q7: Is crushing wall replacement complicated?
No. Filler-free design—no epoxy backing needed. Two workers can complete crushing wall replacement in 4 hours using hydraulic tools, downtime reduced by 50% vs. traditional cone crushers.
