Crushing 万博客户端2.0版本

Crushing involves just what it sounds like—reducing large rocks and mineral deposits to make them into smaller, marketable aggregate products like gravel. Easy, right? Not quite. The type of rock crushers you need—cone, impact, jaw, gyratory, and more—largely depends on your site, the product you want to make, and how much you need to produce. 万博客户端2.0版本 can help you determine the best crushers to meet your project goals every time.

Our Expertise as Aggregate Crushing Specialists

If you are a rock, sand, gravel, or mineral processing industry veteran, you know that there are several different types and styles of crushing equipment.

An individual crusher's construction and capabilities also dictate where in your aggregate processing operations it will fit. That is, you may have multiple types of crushers situated in primary, secondary, tertiary (third), and quaternary (fourth) stations in a circuit format to perform the necessary material reduction work. Each type of crusher brings unique strengths and benefits to the process.

万博客户端2.0版本 specializes in designing the best crusher systems using top-quality brands and equipment to help you extract material, break it down into usable product, and get it to market economically and efficiently.

We've been helping mining operations, asphalt companies, and other industrial material handlers improve efficiency, save money, and move product faster since 1981.

Rock Crusher Types

Here at 万博客户端2.0版本, we source our rock crushers from only the best crusher brands in the business. We also custom-design top-performing crusher systems from the industry's best equipment that will work hard to make finished products like crushed stone, aggregate, sand and gravel, fertilizer, lime, specialty mineral products, recycled asphalt, salt, coal, and slag.

These are just some of the rock crusher types we typically install in primary, secondary, tertiary, quaternary, or final reduction crushing stations depending on their best fit.


Jaw Crusher

Jaw Crushers

Jaw crushers are also known as "rock breakers" and are used to break up larger, harder materials into more manageable pieces. They tend to do well with many different types of materials and don't display as much wear and tear as impact-style rock crushers. They also produce minimal fine materials and dust, though the finished product with this type of rock crusher almost always requires secondary crushing.

Gyratory Crusher

Gyratory Crushers

Gyratory crushers feature a conical head and concave surface (often lined with manganese steel) and break apart material by compression through what is known as eccentric movement. Like jaw crushers, gyratory crushers are often utilized in primary crushing stations, though they may sometimes be used as secondary crushers, as well.

Impact Crusher

Impact Crushers: VSIs and HSIs

Impact-style crushers include vertical shaft impactors (VSIs) and horizontal shaft impactors (HSIs). They are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles. Some operations also use impact-style crushers to achieve a more cubical product after they have already used a different type of rock crusher.

Cone Crusher

Cone Crushers

Similar to jaw and gyratory crushers, cone crushers work by compression, which means they reduce materials by squeezing them until they break apart. Like gyratory crushers, cone crushers are built with a rotating mantle in a concave bowl lined with manganese, but the crushing chamber in cone crushers is not as steeply angled. Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky.

Portable Rock Crusher Plant

Portable Rock Crusher Plants

Depending on the length of your project and how mobile your crushing equipment needs to be, you can choose either stationary or portable/modular crushing plants. These self-contained plants are better suited to smaller projects and can be moved from project to project as necessary.

Everything You Need to Know About Rock Crushers

Do you need to process sand, gravel, minerals, rock, or other aggregate products and have not yet purchased or leased crushing equipment?

Finding the right rock crusher or crushers for your unique operations may seem straightforward, but putting together an efficient crushing circuit is actually a delicately balanced feat of engineering.

Stages of Rock Crushing: Crushing Stations

It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, and tertiary, and quaternary stations are installed to reduce the rock to the desired size, shape, and consistency.

Of course, not all projects require all the stations or stages. Sometimes, primary crushing alone may offer enough reduction for your needs.

after a retrofit

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to three—or even four—stations with a variety of crusher types.

1. Primary Crushing

As the first stage in a crushing circuit following extraction from a mine site, (or in the case of recycled asphalt production, delivery to the RAP processing plant via truck transport), primary crushing reduces material to a size and shape that can be handled by the secondary crusher.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.

2. Secondary Crushing

In secondary crushing, reduction ratios become an essential consideration. Knowing just how fine you need your final output to be, along with the feed requirements of your tertiary or final reduction crushing station, will help you determine how much reduction needs to take place within this stage.

Cone crushers are often placed within the secondary crushing station because they are versatile in terms of feed, closed side setting, speed, and throw. With cone crushers, though, it is essential to operate them at consistent choked settings to keep productivity up.

3. Tertiary/Quaternary/Final Reduction Crushing

The goal of the tertiary (third), quaternary (fourth) or final reduction stage of the crushing process is to size and shape rock or other material into a marketable product. Again, there may be overlap between stages in terms of which crusher styles work best.

Cone crushers, vertical shaft impactors (VSIs), horizontal impact crushers, or even high-pressure grinding roll crushers may be used in the final reduction position.

Types of Rock Determine the Crushers You Need

Sandstone, limestone, gravel, and granite are arguably the most common aggregates used in the construction industry today, but these rocks have very different hardness and abrasiveness characteristics.

The type of rock you plan to focus on processing in your operation will dictate the types of rock crushers you'll need to include in your crushing circuit.

The more you know about the type of rock you wish to crush and what its end-use will be, the easier it is to choose the best equipment to achieve your project goals.
