A CS Cone Crusher (short for Cone Crusher, Symons Type) is a high-efficiency spring cone crusher developed based on the principles of laminating crushing and multi-breaking, less grinding. It is widely used in mining, metallurgy, construction, road building, and chemical industries for crushing hard and medium-hard materials like iron ore, copper ore, limestone, quartz, granite, basalt, etc.

Key Features of CS Cone Crusher:
1. High Efficiency & Energy Saving
– Optimized cavity design and advanced crushing principle improve efficiency.
– Higher speed and stroke combination increase capacity significantly.

2. Excellent Particle Shape
– Laminating crushing reduces needle-shaped particles and improves product gradation.

3. Reliable Hydraulic System
– Hydraulic adjustment and protection ensure stable operation.
– Automatic overload protection prevents damage from uncrushable materials.

4. Durable Structure
– High-quality steel frame and components enhance longevity.
– Thick-walled main shaft for heavy-duty performance.

5. Easy Maintenance & Operation
– Modular design simplifies disassembly.
– Hydraulic cavity clearing reduces downtime.

Technical Parameters (Example: CS Series)
| Model | Max Feed Size (mm) | Discharge Range (mm) | Capacity (t/h) | Motor Power (kW) |
|-|-|||–|
| 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 Secondary Impact Crusher is a type of crushing machine used in aggregate production, mining, and recycling to reduce the size of materials after primary crushing. It is designed to handle softer to medium-hard rocks (e.g., limestone, asphalt, concrete) and produce a more cubical product compared to primary crushers.

Key Features:
1. Function:
– Processes pre-crushed material (from jaw or gyratory crushers) into finer, more uniform sizes.
– Ideal for shaping aggregates and improving particle quality.

2. Working Principle:
– Utilizes impact force from rotating hammers/blow bars striking the material against breaker plates or aprons.
– Material is crushed by high-speed impact and shear forces.

3. Types of Secondary Impact Crushers:
– Horizontal Shaft Impactors (HSI): Common for softer materials; high reduction ratios.
– Vertical Shaft Impactors (VSI): Better for cubical shaping (e.g., sand production).

4. Advantages:
– Produces well-shaped, uniform end products.
– Higher reduction ratio than cone crushers for certain materials.
– Lower operating costs in some applications compared to compression crushers.

5. Applications:
– Aggregate production (road base, concrete, asphalt).
– Recycling (concrete, demolition waste).
– Mining (soft to medium-hard ores).

6. Limitations:
– Not ideal for very hard or abrasive materials (e.g., granite).
– Higher wear on blow bars/hammers than compression crushers.

Comparison with Other Crushers:
– Primary Crusher (Jaw/Gyratory): Handles large raw feed; coarse output.
– Secondary Impact Crusher: Refines material; bet

shape/size control.
– Cone Crusher: Better for hard/abrasive rocks but less cubical output.

Popular Brands/Models:
– Metso Nordberg NP Series
– Sandvik CI Series
– Terex Cedarapids IP Series
– Kleemann MR Series

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
