hard stone crusher spring ne crusher

A hard stone crusher like a spring cone crusher is a robust and efficient crushing machine designed for processing hard and abrasive materials such as granite, basalt, quartz, and other high-hardness rocks. Below is a detailed breakdown of its features, working principle, advantages, and applications:

—

Spring Cone Crusher Overview
– Type: Secondary or tertiary crusher (for medium to fine crushing).
– Mechanism: Uses a spring-based safety system to protect the machine from overload.
– Suitable Materials: Ideal for hard stones (Mohs hardness ≥5) due to its durable structure.

Key Components
1. Crushing Chamber: Composed of a fixed concave and a movable mantle.
2. Spring System: Acts as a safety device to release pressure if uncrushable material enters.
3. Eccentric Shaft: Drives the gyrating motion of the mantle.
4. Adjustment Ring: Allows setting the discharge opening size for different output sizes.

—

Working Principle
1. The motor drives the eccentric shaft, causing the mantle to gyrate.
2. Rocks are compressed between the mantle and concave, breaking into smaller pieces.
3. The spring system ensures stability and protects against tramp iron or overloads.
4. Crushed material exits through the discharge opening.

Advantages for Hard Stone Crushing
1. High Efficiency: Optimized cavity design for better crushing performance.
2. Durability: Made of high-manganese steel or alloy materials to resist wear.
3. Overload Protection: Spring release system prevents damage from uncrushable objects.
4. Adjustable Output: Discharge size can be fine-tuned (typically 3–60 mm).
5. Reliable Operation: Less sensve to material hardness compared to hydraulic cone crushers.

Applications
– Mining (granite, basalt, iron ore).
– Quarrying (aggregate production).
– Construction (road base, concrete aggregates).
– Metallurgy (crushing hard ores).
