Demystifying the 36 Cone Crusher: Specifications and Their Impact
The term “36 Cone Crusher” is deeply ingrained in aggregate and mining operations worldwide. It typically refers to a cone crusher with a 7-foot (approx. 2134 mm) head diameter, tracing its lineage back to the iconic Symons design principles that revolutionized secondary and tertiary crushing. While modern equivalents exist under brands like Metso Nordberg (HP/MP Series), Terex Cedarapids (MVPX), Sandvik (CH/CS Series), and others, understanding the core specifications associated with a “36” cone remains crucial for selection, operation, and optimization.
Why Specifications Matter
Cone crusher specifications aren’t just numbers; they define the machine’s capabilities, limitations, and suitability for your specific application. specs dictate:
Maximum Feed Size: What size rock can it accept?
Capacity: How much material can it process per hour?
Power Requirements: What motor horsepower is needed?
Product Size Range: What particle sizes can it produce?
Physical Dimensions & Weight: Will it fit your site and handling capabilities?
Core Specifications of a Typical Modern 7-Foot / 36 Cone Crusher
While exact figures vary significantly between manufacturers and specific models (e.g., fine vs. coarse chamber configurations), here are typical ranges for a robust modern equivalent designed for secondary crushing:
| Specification | Typical Range | Significance |
| :- | : | :- |
| Head Diameter | 7 ft / 2134 mm | Defines nominal size classification (“36″ cone) |
| Maximum Feed Opening | ~230 – 270 mm (9″ – 10.6″) | Largest lump size crusher can accept |
| Recommended Feed Size | ≤ ~200 mm (8″) | Optimal size for efficient crushing & chamber filling |
| Closed Side Setting (CSS) Range | ~8 – 40 mm (0.3″ – 1.6”) | Primary control over product size; smaller CSS = finer product |
| Power Requirement | ~200 – 300 kW (250 – 400 HP) | Determines drive motor size; impacts throughput & crushability |
| Capacity Range¹ | ~150 – 400 mtph (
