Understanding Crusher Rock: Purpose and Function
Rock crushers, specially designed machines, play a vital role in industries like mining, construction, and recycling. They are responsible for breaking down large rocks into smaller, more manageable pieces for different applications. There are two main groups of rock crushers: compressive crushers, which include primary crushers used in the first stage of the crushing process, like jaw and gyratory crushers, and impact crushers, such as secondary crushers.
Having a crusher rock can provide considerable time and labor savings since manual crushing of materials is not required. A complete rock crushing plant typically employs three to four types of rock crushers, namely primary, secondary, and tertiary/quaternary/final reduction rock crushers.
The upcoming sections will provide a more detailed analysis of the different types of rock crushers and their unique roles during the rock processing stages.
Primary Crusher Rock: The First Step in Rock Processing
Consult with experts and consider factors like cost, mobility, purpose, size, and quality to select the right rock crusher for your project.
The initial stage of rock processing uses primary and secondary crushers, such as jaw or gyratory crushers, to reduce the size of raw materials. Types of primary crushers include compression-style jaw, cone, impact, and gyratory crushers. These crushers are essential for handling larger materials in the primary crushing stage, making them vital for rock processing operations.
Crushing reduces the size of the material and occurs in the crushing chamber, a critical step in the process.
Jaw Crushers
Jaw crushers, which use compressive force, break down large rocks into smaller pieces. Historically, primary crushers have played a significant role in the mining industry, evolving from simple mechanical designs to more advanced and efficient machines. They are generally employed to reduce rock into non-uniformed gravel and are considered more of a blunt instrument compared to cone crushers, which are more suitable for secondary or tertiary, crushing rock down. The Blake Jaw Crusher, invented in 1858, was the first rock crusher to be patented and sold, featuring a key mechanical principle of toggle linkage.
Different types of Blake crushers exist. These include single toggle and double toggle jaw crushers. Single toggle jaw crushers feature one eccentric shaft located at the top of the crusher, while double toggle jaw crushers possess two shafts and two toggle plates. Jaw crushers are generally manufactured with cast iron and/or steel, making them durable and reliable for primary crushing applications.
They produce minimal fine materials and dust, although a secondary fine crushing process is typically required to achieve the desired end product.
Gyratory Crushers
Gyratory crushers, with their conical heads and concave surfaces, compress material through eccentric movement. They are commonly used in primary crushing stations, handling larger quantities of materials to achieve a more uniform shape. These crushers, along with jaw, cone, and impact crushers, play a crucial role in the first stage of the crushing process. They reduce materials to a size and shape suitable for secondary crushers. Gyratory crushers are more efficient and consume less power than fixed jaw front crushers, making them popular for primary crushing applications.
The VSC series cone crusher is a type of gyratory crusher. It offers a higher comminution degree and yield by combining crushing frequency and eccentricity. This results in better cubic-shaped crushed materials. On the other hand, impact crushers can produce excess fine materials with softer rocks, require frequent part changes, and generate significant dust, which can be problematic on some worksites.
Secondary Crusher Rock: Further Size Reduction
The rock processing journey continues with secondary crushing stages. These stages use cone, roller, or impact crushers, including the secondary crusher, to further reduce the size of the rock. This stage is essential for producing graded material for government projects, such as road base and fill.
Next, we will explore the various types of secondary crushers and their applications in more detail.
Cone Crushers
Using an eccentrically gyrating spindle to break down rock enclosed in a concave hopper, cone crushers form a type of rock crusher. Their versatility makes them well-suited for use in secondary crushing stations. Cone crushers adapt to a range of feed, closed side settings, speed, and throw. They operate by compression, squeezing materials until they break apart. They apply pressure to compress the material against a rotating mantle, crushing and breaking it down further until it exits the bottom opening.
Cone crushers are compatible with medium-hard and hard materials, such as virgin rock from quarries hammer mills, and can accept medium-hard to very hard and abrasive feeds, which may be dry or wet but not sticky. Cone crushers produce cubical-shaped products with a reduction ratio ranging from 6-to-1 to 4-to-1. These products are then ready for further processing.
Cone crushers offer reliable construction, increased productivity, improved granularity and shape of finished products, simplified adjustment, and lower operational costs.
Roller Crushers
Roller crushers compress material between two revolving cylinders. They generally produce fine material and are unsuitable for hard or abrasive materials. Although not ideal for all types of rock, roller crushers are useful in applications requiring a fine output.
Despite their limitations, roller crushers can be valuable in secondary crushing when used with the right materials. It’s crucial to consider your project’s specific needs and the material type before selecting the most appropriate crusher.
Impact Crushers
Versatile impact crushers crush material using the force of impact rather than pressure. They come in various configurations, such as Vertical Shaft Impactors (VSIs) that use velocity rather than surface force to break rock, producing a consistent cubical shape. Horizontal Shaft Impactor (HSI) crushers, on the other hand, employ hammers fixed on the outer edge of a spinning rotor to break rock. HSIs are used in a range of industries, including recycling, hard rock and soft materials. They play an important role in many purposes..
The versatility of impact crusher rock makes them suitable for various industries, from mining and construction to recycling. Depending on the specific needs of your project and the type of material you will be processing, an impact crusher may be the right choice for secondary crushing and further size reduction.
Tertiary Crushing Rock and Beyond: Finalizing the Process
The final stage of rock processing, tertiary crushing, uses smaller crushers and screening equipment. This minimizes waste and eases the transfer of materials between stages. The goal is to size and shape rock or other material into a marketable product.
Screening equipment is essential in tertiary crushing operations. Large materials can occupy space and consume energy, causing delays and increasing costs.
Cone crushers, vertical shaft impactors (VSIs), horizontal shaft impactors, impact crushers, and high-pressure grinding roll crushers are viable options for final reduction. Each is in the right context. Choosing the right tertiary crusher and screening equipment depends on your project’s specific needs and the type of material you will be processing.
Comparing Crusher Rock Types: Making the Right Choice
When choosing a rock crusher for your project, comparing the range of types available is crucial. Primary crushers, such as compression-style jaw, cone, impact crushers, and gyratory crushers, play a key role in the first stage of the crushing process by reducing materials to a size and shape that can be handled by secondary crushers. Here are some options to consider:
- Jaw crushers
