What are Tertiary Impact Crusher and Horizontal Shaft Crusher?

A tertiary impact crusher is a machine used in the final stage of crushing to achieve the desired particle size of the material. It is designed to handle fine materials, often producing a high-quality, uniform product. This type of crusher is ideal for applications where precision is critical, such as in the production of sand or fine aggregates. Tertiary impact crushers efficiently reduce the size of materials, such as limestone, asphalt, and concrete, to the required specifications by using high-speed rotor movement and impact plates to fracture the material.

A horizontal shaft crusher, on the other hand, is a type of impact crusher where the rotor operates horizontally. This crusher uses a high-speed rotating shaft with wear-resistant hammers or blow bars to impact and break down materials. The design is particularly effective for crushing soft to medium-hard materials like limestone and gypsum and is widely used in aggregate production, recycling, and mining. The horizontal configuration ensures effective reduction of large materials and offers flexibility in achieving different crushing ratios and product sizes by adjusting the rotor speed and crusher settings.

What is the difference between vertical and horizontal shaft?

1. Vertical Shaft Impact Crushers (VSI)

a.Design and Operation

Vertical shaft impact crushers (VSIs) have a vertical rotor configuration. The material to be crushed is fed into a central chamber where it is accelerated by high-speed rotors and flung outward to impact the outer walls of the chamber or a series of anvils. The vertical orientation allows for a unique method of crushing through the application of high-speed impacts, often leading to the production of fine and well-shaped particles.


VSIs are commonly used for producing high-quality, specifically shaped aggregates and sand. They are often employed in the production of material for concrete and asphalt industries, where precise shape and size of aggregate particles are crucial. Additionally, VSIs are popular in the recycling industry for crushing recyclable materials such as glass, slag, and industrial minerals.

c. Advantages

- Excellent for producing cubical, well-graded particles.
- Ideal for fine crushing and shaping applications.
- Versatile in processing a variety of materials.

2. Horizontal Shaft Impact Crushers (HSI)

a. Design and Operation

Horizontal shaft impact crushers (HSIs) have a horizontal rotor configuration. The material enters a crushing chamber where it encounters fast-rotating hammers or blow bars mounted on the rotor. These hammers strike and break the material against impact plates or curtains positioned around the rotor. The horizontal orientation facilitates the breaking down of material through a combination of impact force and shear.

b. Applications

HSIs are widely used for primary, secondary, and tertiary crushing of hard rocks and minerals. They are particularly effective for processing softer to medium-hard materials such as limestone, coal, gypsum, and other natural stones. HSIs are also commonly used in recycling operations to process materials like concrete and asphalt, enabling the recovery and reuse of construction and demolition debris.

c. Advantages

- Suitable for handling larger, coarse materials and initial stages of crushing.
- Versatile in applications from primary to tertiary crushing.
- Efficient in producing high reduction ratios and handling high-capacity throughput.

3. Key Differences:

a. Rotor Orientation

- VSI: Vertical rotor.
- HSI: Horizontal rotor.

b. Crushing Mechanism

- VSI: Utilizes high-speed impacts in a vertical chamber for fine and cubic particle production.
- HSI: Uses impact force and shear from horizontally positioned blow bars for breaking and reducing material size.

c. Typical Applications

- VSI: Ideal for creating fine, well-shaped aggregates and sand, especially in the concrete and asphalt industries.
- HSI: Suitable for a broader range of crushing stages and materials, including primary crushing and recycling operations.

d. Output Characteristics

- VSI: Produces high-quality, uniform, and cubical particles, often used for specific shaping tasks.
- HSI: Capable of handling larger feed sizes and producing a wider range of particle sizes for different crushing stages.

Both types of crushers have their unique strengths and are chosen based on the specific requirements of the application, including the nature of the material to be crushed and the desired product characteristics.

Which type of crusher is best?

Advantages of Tertiary Impact Crushers Over Primary and Secondary Crushers

1. Finer Crushing Capabilities

Tertiary impact crushers are specifically designed to reduce materials to finer particle sizes. While primary crushers are used for the initial stage of reducing large, raw materials and secondary crushers provide a medium-range crushing, tertiary crushers excel in producing finely crushed materials that meet specific size and shape requirements. This makes them ideal for creating fine aggregates and sand necessary for high-quality construction materials.

2. Higher Quality Output

The design and operation of tertiary impact crushers allow for better control over the end-product's size and shape. The result is a higher quality, consistent output with well-graded, uniform particles. This is particularly important in industries such as concrete and asphalt production, where the quality of aggregate materials directly impacts the durability and strength of the final product.

3. Enhanced Efficiency

Tertiary crushers often incorporate advanced design features and technologies that improve their efficiency and effectiveness. This includes adjustable settings that allow operators to customize the crusher to meet precise material specifications. The ability to efficiently produce finely crushed materials with less energy consumption and lower operating costs is a significant benefit compared to primary and secondary crushers, which are more suited for rough, bulk reduction.

4. Versatility and Flexibility

Tertiary impact crushers are versatile machines capable of handling various types of materials, from soft to medium-hard stones and minerals. They are equipped to produce different product sizes and shapes by adjusting rotor speed, impact plates, and other settings. This flexibility makes them suitable for a wide range of applications beyond standard crushing tasks, including recycling operations and the production of specialized mineral products.

Preferred Applications of Tertiary Impact Crushers

1. Construction Industry

Tertiary impact crushers are prominently used in the construction industry for producing fine aggregates and sand. These finely crushed materials are crucial for making high-quality concrete, asphalt, and other construction materials. The ability to produce uniform and precisely shaped particles means better performance and durability of construction structures like roads, bridges, and buildings.

2. Recycling Industry

In recycling operations, tertiary impact crushers are highly effective in processing demolition waste, such as concrete, asphalt, and bricks. They break down the waste materials into fine, reusable aggregates, promoting sustainable construction practices by reducing landfill waste and conserving natural resources.

3. Mining Industry

The mining sector also benefits from tertiary impact crushers as they are essential in the mineral processing stages. Tasks such as the production of finely crushed minerals like limestone, gypsum, and other materials prepare these raw resources for further processing steps, such as milling and beneficiation. Their ability to produce consistent, fine particles aids in the overall efficiency of the mining operation.

4. Industrial Mineral Applications

Tertiary impact crushers are used in industrial mineral applications where precision and fine particle sizes are critical. This includes the manufacture of products like glass, ceramics, and certain types of chemical compounds, where the uniformity and fine grading of the raw materials play a crucial role in the final product's quality and performance.

In summary, tertiary impact crushers provide a range of advantages over primary and secondary crushers in applications where finer, high-quality output is required. They are versatile and efficient machines, capable of handling a variety of materials and preferred in industries where precision and product quality are paramount.
