MoleDive Horizontal Shaft Impact Crusher Guide

1. What is horizontal shaft impact crusher?

A Horizontal Shaft Impact Crusher (HSI Crusher) is a type of crusher that utilizes a horizontal shaft to impel the material to be crushed against the anvils or curtain walls of the crusher. The material is broken into smaller pieces by the impact of hammers, often referred to as blow bars, and thrown against the anvils or curtain walls.

Horizontal Shaft Impact Crushers are known for their high reduction ratios, especially when processing soft and medium-hard materials. They are commonly used in the production of construction aggregates, sand, and minerals. The horizontal shaft design allows the material to exit the crusher at a high velocity, creating a consistent and cubical product shape.

These crushers are widely used in industries such as mining, metallurgy, construction, and recycling, providing efficient and reliable crushing solutions for various applications.

2. What is an impact crusher?

An impact crusher is a device that crushes material by striking or smashing, sometimes with the help of a revolving rotor or impeller. The rotor accelerates the material as it enters the crushing chamber, causing it to contact the fixed anvils or curtains inside the crusher at a high speed. The substance is broken up into tiny fragments by this collision.

Because of their versatility, impact crushers are frequently utilized in a variety of sectors, including demolition, recycling, mining, and construction. They are renowned for their capacity to yield a cubical-shaped product with a high reduction ratio. Impact crushers come in several varieties, such as vertical shaft impact crushers (VSI) and horizontal shaft impact crushers (HSI), each having unique benefits and uses.

3. How does a vertical shaft impact crusher work?

In order to break materials into tiny pieces, a Vertical Shaft Impact (VSI) crusher accelerates the materials via a high-speed rotor and throws them against a fixed outside surface, such as anvils or curtains. The material is supplied into the center of the rotor, where it collides with the immovable anvils or curtains due to the centrifugal force created by the revolving motion.

Particle size and shape are reduced as a result of the material’s rapid velocity and strong collision with the anvils. VSI crushers are widely employed in the manufacture of sand and fine aggregate for uses in construction and road building because of their reputation for producing final products with a cubic form.

4. What is a HSI crusher?

A Horizontal Shaft Impact (HSI) crusher is a type of crusher that utilizes a horizontal shaft to break down materials by impacting them with hammers or blow bars fixed on the outer edge of a spinning rotor. The rotor generally rotates at high speeds, and when the material is fed into the crusher, it is struck by the rotating hammers or blow bars.

 

The impact of the hammers or blow bars against the material results in the reduction of size and fragmentation. HSI crushers are versatile and commonly used in applications where the target is to produce high-quality cubic-shaped aggregates, such as in the production of concrete and asphalt.

HSI crushers can handle various types of materials, including soft to hard rock, and are effective for primary, secondary, or tertiary crushing depending on the specific application and configuration.

5. What is the difference between vertical and horizontal impact crushers?

The primary difference between vertical shaft impactors (VSI) and horizontal shaft impactors (HSI) lies in the orientation of the crushing chamber and the axis of the rotor.

Orientation:

Vertical Shaft Impactor (VSI): The crushing chamber is vertically oriented, and the rotor is mounted vertically. The material enters the crusher from the top and is subjected to high-speed impact forces as it travels down through the crushing chamber.

Horizontal Shaft Impactor (HSI): The crushing chamber is horizontally oriented, and the rotor is mounted horizontally. The material enters the crusher from the side and is subjected to impact forces as it travels across the width of the crushing chamber.

Rotor Design:

VSI: The rotor of a VSI crusher is often configured as a shoe and anvil assembly or a rock-on-rock rotor where the material is accelerated against a stationary surface (anvils or rocks) to break it down.

HSI: The rotor in an HSI crusher typically consists of a series of horizontal bars or hammers that impact the material.

Applications:

VSI: Commonly used for shaping and producing cubical-shaped aggregates in applications like making sand, whereas some can be configured for tertiary crushing.

HSI: Versatile crushers used for primary, secondary, or tertiary crushing of a variety of materials, including softer materials.

Particle Shape:

VSI: Well-suited for producing cubical-shaped particles due to the high-speed impact and crushing mechanism.

HSI: Can produce a mix of cubical and angular particles, depending on the application and specific design.

In summary, the main distinctions lie in the orientation of the crushing chamber, the axis of the rotor, and the resulting impact forces on the material, leading to differences in applications and the produced particle shapes.

6.What factors should be considered when selecting a crusher for a specific application?

 Factors such as feed size, desired product size, material characteristics, production requirements, and the cost-effectiveness of the crusher should be considered during the selection process.

7. Can crushers handle different types of materials, or are they designed for specific applications?

Crushers are designed for a wide range of materials. While some are specialized for certain applications (e.g., asphalt crushers), many crushers are versatile and can handle various materials, including aggregates, minerals, and recycled materials.

8. How does regular maintenance impact the performance and lifespan of a crusher?

Regular maintenance, including lubrication, inspection of wear parts, and addressing potential issues promptly, is crucial for ensuring optimal performance and extending the lifespan of a crusher.

9. Are crushers suitable for mobile applications, such as in construction projects or mining sites?

Yes, many crushers, including mobile impact crushers and portable jaw crushers, are designed for on-site mobility, making them suitable for various applications in construction, mining, and other industries.

10. What safety measures should be taken when operating a crusher?

Safety is paramount when operating crushers. Operators should follow proper procedures, wear appropriate personal protective equipment (PPE), and be trained on the safe operation and maintenance of the specific crusher they are using.

11. Can crushers be used for recycling purposes, and how do they contribute to sustainable practices?

Yes, crushers play a crucial role in recycling by reducing the size of materials for reuse. They contribute to sustainable practices by facilitating the recycling of construction waste, concrete, asphalt, and other materials, reducing the need for new raw materials.
