What is a Concrete Crusher?

A concrete crusher is a professional crushing and recycling equipment that can crush road materials, reinforced concrete, waste concrete, etc. It is widely used in sand and gravel plants, mixing plants, demolition sites, and municipal engineering projects.

What Types of Concrete Crushers are There?

1. Classification by Structure: 

    Jaw Crusher. Jaw crushers are the main equipment for crushing large concrete blocks. Due to their large feed capacity and durability, they are mainly used in the initial stage of crushing boulders, granite, basalt, ores, and construction waste, and are usually used for coarse crushing.

Advantages: Large feed size, suitable for coarse crushing of hard rocks.

Applicable materials: Construction waste and various mineral rocks, such as granite, basalt, pebbles, limestone, and ores.

    Impact Crusher: An impact crusher is a medium-fine crushing equipment, generally used for secondary crushing, producing high-quality aggregate with good shape.

Advantages: Cubic aggregate, high quality, good shape, lower investment cost than cone crushers.

Applicable materials: Limestone, concrete waste, and other medium-hardness stones.

    Cone Crusher: A cone crusher is a medium-fine crushing equipment, usually used for fine crushing, mainly for crushing high-hardness, highly abrasive stones.

Advantages: Minimal wear, high output.

Applicable materials: High-hardness stones.

    Hammer Crusher: A hammer crusher uses high-speed rotating hammers to strike materials, mainly used for crushing softer stones.

Advantages: One-time forming, no secondary crushing required.

Applicable materials: Concrete, shale, gypsum, coal gangue, limestone, etc.

    Sand Making Machine:In a sand and gravel production line, the sand making machine is a key piece of equipment that uses high-speed impact crushing of stone to produce sand.

Advantages: Good particle shape of output, can replace natural sand, stable output.

Applicable Raw Materials: Ore, granite, basalt, limestone, pebbles, construction waste, etc.

2.Classification by Mobile and Fixed Type

    Fixed Concrete Crusher

A fixed concrete crusher consists of a feeder, crusher, screening machine, and conveyor, installed in the production area and equipped with a foundation.

Advantages: Stable operation, high output, durable equipment, long service life, low operating costs, suitable for long-term large-scale production of recycled aggregates.

    Mobile Concrete Crusher

A mobile concrete crusher is an integrated machine with a wheeled chassis, which can directly drive into the construction site for concrete crushing.

Advantages: Flexible relocation, adaptable to any construction site, no foundation required.

Besides the crusher, what other key equipment is needed in a crushing production line?

1. Vibrating feeder: Provides a stable feed to the crusher, avoiding blockages and material jamming.

2. Belt conveyor: Used to transport finished products and aggregates, connecting the entire production line for automated operation.

3. Vibrating screen: Used to filter sand and gravel of different sizes, grading the output to meet different particle size requirements.

4. Magnetic separator: Used to remove iron blocks, steel wires, and reinforcing bars from concrete, protecting the stone crusher.

5. Sand washing machine: Used to clean the crushed sand and gravel aggregates, obtaining cleaner sand.

6. Dust collector: Used to reduce dust.

7. Electrical control cabinet: One-button start/stop.

How to choose the right concrete crusher? 

1. For crushing hard materials (iron ore, granite, and basalt):

We recommend a jaw crusher + cone crusher. The jaw crusher is used for coarse crushing, and the material is then fed into the cone crusher for medium and fine crushing.

2. For crushing soft materials (weathered rock, coal gangue, limestone):

We recommend a jaw crusher + impact crusher or hammer crusher. Hammer crushers and impact crushers are more commonly used for crushing soft rock.

3. For producing high-quality aggregates, highway aggregates, and commercial concrete:

We recommend an impact crusher. Impact crushers produce aggregates with good particle size and high quality.

4. For producing artificial sand:

Simply add an impact crusher and sand washing machine to the production line.

5. What kind of crusher should a small, newly established investor choose?

We recommend a popular small mobile crushing plant. It requires little investment and offers quick returns.

To help our engineers recommend the ideal concrete crusher for you, please provide us with the following information:

1. What type of material do you need to crush?(Pebbles, granite, basalt, limestone, ,construction waste)

2. Feed particle size?(how big material stones?)

3. Hourly output (tons per hour)

4. Output particle size?(0-10mm,10-20mm,20-40mm?)
