| Feature | Specification |
|---|---|
| Definition & Function | The Spider Cap is a fixed component mounted on the top of the hydrocone spider. It protects the head center of the main shaft, guides incoming material, prevents foreign particle ingress, and ensures uniform load distribution. |
| Material | Heavy-duty carbon steel; options include MO40 or manganese steel for high abrasion resistance; pressure- and corrosion-resistant. |
| Types | – Standard (for 36 inch hydrocone) – Custom (compatible with models 36‑2, 36‑4, 36‑5) – Wear-resistant coated (for hard rock mining) |
| Dimensions & Weight | – Diameter: 300–500 mm (typical: 400 mm) – Height: 100–200 mm – Approx. Weight: 20–50 kg (depending on model) – Mounting Holes: 4–6 |
| Performance & Capacity | – Capacity: suitable for 50–200 t/h (aligned with hydrocone) – Speed: 900–1500 rpm (with main shaft) – Service Life: 2,000–5,000 hours with proper maintenance |
| Applications | – Open-pit mining (sand, gravel, slate) – Primary/secondary crushing in hydrocone crushers – Cement and construction industries; protection of moving components |

The Hydrocone Spider Cap is a component made from wear-resistant steel, installed at the center of the crusher’s top shell. Its primary function is to prevent aggregates and solid particles from entering the upper section of the main shaft.
The main shaft controls the rotational movement of the crusher cone, and the ingress of any debris into this area can cause severe damage to the machine.
Wear-resistant steel is chosen for the hydrocone spider cap due to its exceptional resistance to abrasion, corrosion, and impact. Crushers are continuously exposed to wear and impact from aggregates, and using inferior material for the spider cap would result in rapid erosion and early failure.
Wear-resistant steel can withstand high pressure and abrasive conditions, significantly extending the service life of the spider cap and reducing costs associated with premature replacement.
Failure of the hydrocone spider cap can lead to serious consequences for the crusher:
Main Shaft Damage: Abrasion and friction from aggregate particles can harm the main shaft and disrupt smooth rotation.
Reduced Efficiency: A damaged spider cap and particle ingress into the main shaft can significantly decrease crusher performance and throughput.
Increased Wear: Failure of the spider cap can affect other crusher components, accelerating overall wear.
High Maintenance Costs: Replacing the hydrocone spider cap and other damaged parts can incur substantial expenses.
To prevent failure of the Hydrocone Spider Cap and maintain optimal crusher performance, regular inspection and maintenance are essential:
Routine Inspection: Check the spider cap regularly for cracks, wear, or any visible damage.
Timely Replacement: Immediately replace the spider cap with a new unit if any signs of wear or damage are observed.
Use Genuine Spare Parts: Only use original, high-quality spare parts for replacement to ensure proper fit and durability.

“We purchased the 36-inch Hydrocone Spider Cap from Novincsm for our production line. The wear-resistant material was our top priority, and after several months of continuous operation, we haven’t observed any quality degradation or cracking. Its durability has been completely satisfying.”

Thank you for sharing your experience 🙏
We’re glad to hear that the 36-inch Hydrocone Spider Cap from Novincsm has met your expectations.
You are absolutely correct—wear-resistant material plays a critical role in this component. The spider cap is directly exposed to constant pressure, impact, and abrasion. Using alloyed, wear-resistant steel with standard heat treatment ensures that the part:
Resists cracking or chipping over time
Maintains its shape and performance during continuous operation
Minimizes downtime and replacement costs
The fact that you haven’t observed any quality degradation after several months of continuous operation is exactly what you should expect from a properly engineered and standard-compliant spider cap.
If you have any questions in the future regarding replacement intervals, proper maintenance, or coordination with other hydrocone components, the Novincsm team is always here to support you 🌱
