A Spring Cone Crusher is a type of secondary or tertiary crushing equipment widely used in mining, metallurgy, construction, and aggregate production. It utilizes a spring-based safety system to protect the crusher from damage caused by uncrushable materials (e.g., tramp iron) and overload conditions.

Key Features:
1. Spring Release System:
– Acts as an overload protection mechanism. When uncrushable material enters the crushing chamber, the springs compress, allowing the mantle to lift and discharge the foreign object without damaging the machine.

2. Crushing Principle:
– Operates on a gyratory motion where the mantle gyrates against the concave (fixed liner), compressing and breaking rocks into smaller pieces.

3. Adjustable Discharge Setting:
– The gap between the mantle and concave can be adjusted to control the output size of crushed material.

4. Applications:
– Suitable for medium to hard rocks (e.g., granite, basalt, iron ore).
– Used in secondary or tertiary crushing stages in quarrying and mining.

5. Advantages:
– Reliable and durable design.
– Lower maintenance compared to hydraulic cone crushers (but less advanced in automation).
– Cost-effective for small to medium-scale operations.

Components:
– Main Frame – Supports the crushing mechanism.
– Eccentric Shaft – Drives the gyratory motion of the mantle.
– Mantle & Concave – Wear parts that directly crush materials.
– Springs – Provide tension and safety release.
– Transmission System – Includes belts, pulleys, or direct drive.

Comparison with Hydraulic Cone Crusher:

| CS75 | ≤115 | 9-45 | 45-91 | 75 |
| CS160 | ≤150 | 13-38 | 109-181 | 160 |
| CS240 | ≤240 | 16-51 | 172-349 | 240 |

Applications
– Secondary & tertiary crushing in mining.
– Aggregate production for construction.
– Industrial mineral processing (e.g., cement plants).

Comparison with Other Crushers
– vs HP Cone Crusher: CS uses a spring-based system; HP uses hydraulic pressure for adjustment.
– vs Jaw Crusher: CS provides finer output but requires pre-crushing by a jaw crusher for large rocks.

Maintenance Tips
1. Regularly check lubrication system (oil level & quality).
2. Monitor wear parts (mantle, concave).
3. Ensure proper belt tension and alignment.

An Impact Crusher is a type of crushing machine that uses impact force to break down materials. It is widely used in mining, construction, and recycling industries to crush rocks, concrete, and other hard materials into smaller, uniform-sized particles.

How an Impact Crusher Works:
1. Material Entry: Feed material enters the crushing chamber.
2. High-Speed Rotor Impact: A rotating rotor with hammers or blow bars strikes the material at high speed.
3. Impact & Shattering: The material is thrown against stationary impact plates (anvils), causing it to break apart.
4. Size Control: Adjustable aprons or curtains control the output size by regulating how long particles stay in the crushing zone.
5. Discharge: Crushed material exits through the bottom.

Types of Impact Crushers:
1. Horizontal Shaft Impact Crusher (HSI)
– Uses a horizontal rotor with hammers/blow bars.
– Best for softer materials like limestone and recycled concrete.
– Produces a more cubical product.

2. Vertical Shaft Impact Crusher (VSI)
– Uses a vertical rotor with high-speed impellers.
– Ideal for shaping hard and abrasive materials (e.g., sand production).
– Provides better particle shape for aggregates.

Advantages:
✔ High reduction ratio (up to 20:1)
✔ Good cubical product shape (better than jaw crushers)
✔ Efficient for medium-hard to soft materials
✔ Adjustable output size

Disadvantages:
✖ Higher wear on blow bars/hammers (especially with abrasive materials)
✖ Less effective for very hard rocks compared to cone crushers

Applications:
– Quarrying & mining (limestone, coal, etc.)
– Recycling (concrete, asphalt demolition waste)
– Aggregate production for construction

A jaw crusher is a primary crushing machine used in mining, construction, and recycling industries to break down large rocks, ores, and other hard materials into smaller, more manageable pieces. It operates by compressing the material between two jaws—one fixed and one moving—to reduce its size.

Key Components of a Jaw Crusher:
1. Fixed Jaw (Stationary Die) – The immovable surface that forms part of the crushing chamber.
2. Moving Jaw (Swing Jaw) – Moves back and forth against the fixed jaw, applying mechanical pressure.
3. Toggle Plate – A safety mechanism that protects the crusher from damage due to uncrushable material.
4. Eccentric Shaft – Drives the moving jaw in an elliptical motion for crushing action.
5. Flywheel – Stores energy to ensure smooth operation.
6. Cheek Plates – Protective liners on the sides of the crushing chamber.

How It Works:
1. Material is fed into the top of the crusher.
2. The moving jaw exerts force on the rock by pressing it against the fixed jaw.
3. Crushed material exits through the discharge opening at the bottom (adjustable for different sizes).

Types of Jaw Crushers:
– Single Toggle Jaw Crusher – Simpler design with only one toggle plate; efficient for smaller operations.
– Double Toggle Jaw Crusher – More complex but provides better crushing force for harder materials.

Applications:
– Mining (crushing gold, copper, iron ore)
– Construction (breaking concrete, asphalt)
– Recycling (demolition waste processing)
– Quarrying (limestone, granite, gravel)

Advantages:
✔ High reduction ratio
✔ Simple structure & easy maintenance
✔ Suitable for hard and abrasive materials

Disadvantages:
✖ Higher wear on jaw plates compared to gyratory crushers
✖ Less efficient for sticky or wet materials
