A Spring Cone Crusher is a type of secondary or tertiary crushing equipment widely used in mining, metallurgy, construction, and aggregate production. It is designed to crush hard and medium-hard materials like iron ore, limestone, granite, basalt, and quartz.

Key Components & Working Principle
1. Crushing Chamber: Consists of a fixed concave (outer liner) and a movable mantle (inner cone) that gyrates under eccentric motion.
2. Spring Safety System: A set of springs around the frame acts as an overload protection mechanism. If uncrushable material enters the chamber, the springs compress to widen the discharge opening and release the foreign object, preventing damage.
3. Eccentric Shaft & Rotation: Driven by a motor via belts/pulleys, the eccentric shaft causes the mantle to oscillate, crushing material against the concave.
4. Discharge Adjustment: The gap between the mantle and concave can be adjusted to control output size (coarse to fine).

Advantages
– Reliable Overload Protection: Springs absorb shock from tramp iron or hard materials.
– High Crushing Efficiency: Suitable for medium/fine crushing with good particle shape.
– Simple Structure & Low Maintenance: Fewer hydraulic components compared to hydraulic cone crushers.

Limitations
– Less automated than hydraulic cone crushers (e.g., no real-time

justment).
– Lower capacity compared to modern hydraulic models for large-scale operations.

Applications
– Mining (iron ore, copper ore).
– Quarrying (limestone, granite).
– Road construction aggregates.

Comparison with Hydraulic Cone Crusher
| Feature | Spring Cone Crusher | Hydraulic Cone Crusher |
|–|–|–|
| Overload Protection | Mechanical springs | Hydraulic cylinders |
| Adjustment | Manual | Automatic (hydraulic) |
| Cost | Lower | Higher |
| Automation | Limited | Advanced (e.g., PLC control)|

For modern high-capacity or automated crushing plants, hydraulic cone crushers are often preferred. However, spring cone crushers remain cost-effective for small-to-medium operations requiring robustness and simplicity.

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, more manageable sizes.

How Does an Impact Crusher Work?
1. Feeding: Material enters the crusher through a feed hopper.
2. Rotor & Blow Bars: A high-speed rotor with attached blow bars (hammers) strikes the incoming material.
3. Impact Crushing: The material is thrown against impact plates (or aprons), where it breaks due to the force of impact.
4. Adjustable Settings: The gap between the rotor and impact plates can be adjusted to control the output size.
5. Discharge: Crushed material exits through the discharge opening.

Types of Impact Crushers
1. Horizontal Shaft Impact Crusher (HSI)
– Uses a horizontal rotor with blow bars.
– Ideal for softer materials like limestone and recycled concrete.
– Commonly used in aggregate production.

2. Vertical Shaft Impact Crusher (VSI)
– Uses a vertical rotor with high-speed impellers.
– Produces finely shaped cubical aggregates (sand-making).
– Often used in sand production and fine crushing.

Advantages of Impact Crushers
✔ High reduction ratio (up to 20:1)
✔ Good particle shape (cubical output)
✔ Versatile for soft to medium-hard materials
✔ Lower operational costs compared to jaw or cone crushers

Common Applications
– Quarrying & mining (limestone, granite, etc.)
– Recycling (concrete, asphalt demolition waste)
– Aggregates production for construction
– Sand manufacturing (VSI crushers)

Limitations
❌ Not ideal for very hard or abrasive materials (e.g., basalt) without wear-resistant linings.
❌ Higher wear on blow bars and impact plates compared to compression crushers.

A Secondary Impact Crusher is a type of crushing machine used in aggregate production, recycling, and mining operations to reduce the size of materials after primary crushing. It is designed to handle softer to medium-hard materials (e.g., limestone, asphalt, concrete, demolition waste) and produce a more uniform, cubical end product compared to primary crushers.

Key Features of a Secondary Impact Crusher:
1. Purpose:

– Ideal for producing high-quality, well-shaped aggregates for construction (roads, concrete).

2. Working Principle:
– Uses high-speed impact forces (rotor with hammers/blow bars) to break materials.
– Material is fed into the crushing chamber and struck by rotating blow bars before being thrown against impact aprons/liners for additional fragmentation.

3. Advantages:
– Produces a more uniform, cubical product (better for asphalt and concrete).
– Higher reduction ratio than cone crushers in certain applications.
– Adjustable output size via hydraulic or mechanical settings.
– Handles moderately abrasive materials efficiently.

4. Disadvantages:

5. Common Applications:
– Crushing limestone, recycled concrete, asphalt, and demolition debris.
– Aggregate production for road base, railroad ballast, and construction fill.

6. Types of Secondary Impact Crushers:
– Horizontal Shaft Impactors (HSI): Most common for secondary crushing; material is fed horizontally into the rotor.
– V

ical Shaft Impactors (VSI): Used for shaping and fine crushing (more common in tertiary stages).

2. Horizontal Shaft Design – Uses rotating hammers or blow bars to strike and throw material against breaker plates.
3. Versatility – Can handle soft to medium-hard rocks (limestone, gypsum, coal) and some abrasive materials.
4. Adjustable Output Size – The gap between the rotor and impact aprons can be adjusted to control product size.
5. High Throughput Capacity – Suitable for high-production quarrying, mining, and recycling applications.

Advantages Over Other Primary Crushers:
– Better cubical-shaped end product compared to jaw crushers.
– Higher reduction ratio in a single stage.
– Effective for softer materials where compression crushers may generate excessive fines.

Common Applications:
– Quarrying & Aggregates (limestone, gravel)
– Cement Industry (crushing raw materials)
– Recycling (concrete, asphalt demolition waste)
– Mining (primary reduction of ore)

Popular Models & Manufacturers:

A jaw crusher is a primary crushing machine used in mining, quarrying, and construction industries to reduce large rocks, ores, or other hard materials into smaller, more manageable pieces. Here’s a detailed breakdown:

How It Works
1. Crushing Mechanism:
– A jaw crusher consists of two vertical jaws—one fixed (stationary) and one movable (swing jaw).
– The movable jaw exerts force on the material by pressing it against the fixed jaw.
– Material is crushed progressively until small enough to pass through the bottom gap (discharge opening).

2. Key Components:
– Fixed Jaw Plate: Attached to the crusher frame.
– Movable Jaw Plate: Driven by an eccentric shaft (pitman) that creates an elliptical motion.
– Toggle Plate: Safety mechanism to protect the crusher from overload.
– Flywheel: Stores energy for consistent crushing force.

Types of Jaw Crushers
1. Blake (Double Toggle): Older design with a pivoted swing jaw; robust but less efficient.
2. Dodge (Single Toggle): Movable jaw pivots at the bottom; simpler but limited in capacity.
3. Universal (Overhead Eccentric): Modern single-toggle design with higher efficiency and adjustability.

Applications
– Primary crushing of hard materials (granite, basalt, iron ore).
– Recycling concrete and demolition waste.
– Laboratory-scale crushing for research.

Advantages
– Simple structure, low maintenance.
– High reduction ratio (typically 6:1 to 8:1).
– Handles abrasive materials well.

Disadvantages
– Less efficient than gyratory crushers for high-capacity needs.
– Wear-prone parts (jaw plates) require regular replacement.

Maintenance Tips
– Regularly check jaw plates for wear and replace as needed.
– Lubricate bearings and eccentric shafts to prevent overheating.
– Monitor discharge settings to ensure optimal particle size output.
