Which Rock Crusher is Right for You?

It&#;s easy to know the role of a rock crusher &#; the name gives it away. It crushes large rocks into useable sizes while making handling and transporting of them more manageable. But after that, the lines can get fuzzy about which is best for your specific needs.

Different rock crushers focus on various tasks and a variety of applications. They have their own specialties, and understanding what those are will help you figure out which one is your best choice.

When considering which crusher suits your requirements the best, ask yourself where you will use it:

• At a Demo Site. Crushers on a building demolition site compress and recycle materials like concrete, asphalt, and brick. These crushed materials can be reused as a base for new construction projects or as aggregate.
• In a Quarry. These rock crushers break down huge rocks like limestone, granite, and sandstone. These materials can then be used for construction, road base, landscaping, and oil fracking.
• On the Road. You&#;ve probably driven by dozens of rock crushers while trying to navigate your way through the middle of road construction projects. Material crushed on a road job is reused under or in the new road.
• In the Mine.Mining rock crushers break down materials into smaller pieces for easier removal and downstream processing for taking out essential minerals and metals.
• Sand and Gravel.This is one of the most unique of crushing applications. Round boulders are one of the hardest materials to crush because of compressive strength and also one of the more challenging materials due to the shape.
• A Recycling Yard. These crushers help process materials, including concrete, asphalt, and demolition waste, that can be recycled into something new. This lessens the need for new products and reduces waste. It&#;s a win-win.

Which one is Right for You?

Just as you wouldn&#;t buy a five iron to putt a golf ball, you must invest in the proper rock crusher for the job. Let&#;s review three types of crushers and what they are meant to accomplish.

Jaw Crushers serve many purposes and work in quarries, mines, and recycling sites. They do the job by squeezing rocks between a fixed side and a moving side. A few features that make them successful are their ability to adjust the jaw setting, controlling the crushed rocks&#; size, and not having fancy parts to maintain, so upkeep is easy.

Use jaw crushers for:

• Primary crushing tasks, making large rocks into smaller ones for further processing.
• Quarrying and mining duties, where they process many types of rocks and minerals.
• Demolition and recycling jobs are no match for a jaw crusher. It easily reprocesses concrete, asphalt, and other crushable materials.

Impact Crushers use brute force to crush materials. They come in various forms, including horizontal and vertical shaft impactors. They are best for significantly reducing the materials being crushed, producing quality end-product size, working well with many kinds of materials, and are made with easy maintenance and quick repairs in mind.

Use impact crushers for:

• Primary and secondary crushing applications in limestone and softer materials.
• Recycling work involving concrete, asphalt, and demolition surplus.
• Generating well-graded aggregates for all kinds of construction projects.

Cone Crushers are multipurpose machines perfect for secondary and tertiary crushing stages. Staying true to its name, this machine has a cone-shaped crushing surface with an eccentric crushing motion. Cone crushers are versatile because they handle almost anything, from hard and abrasive rocks to softer materials. They create refined end products and are typically made with features that are energy efficient.

Use cone crushers for:

• Jobs after the primary crushing applications.
• Finish sizing aggregates and ores at mining sites.
• Creating first-rate sand and gravel products.

Configurations

Crushers are typically combined with other components like feeders, hoppers and conveyors and mounted on a frame or chassis. Depending on individual needs, plants can be stationary/modular, track-mounted mobile, or wheel portable.

Stationary and Modular Crushing Plants

Stationary plants typically reside in rock quarries and mine sites where they never move and stay for the plant&#;s entire life. They require a larger footprint and considerable infrastructure like buildings, walls, pads, and ramps to support the equipment.

Staionary equipment doesn&#;t move, which means that the feed source is continually moving further away from the crusher. This means longer loader cycling times, increased fuel consumption and wear and tear on equipment.

As the distance increases, material must be brought to the crusher by pushing it with a bulldozer, conveying, or hauling with trucks.

In contrast, wheeled and mobile plants can easily and quickly move from one location to another or maintain proximity to the feed source. Portability also makes it easier to replace one machine for another in the event of breakdowns or upgrades.

Mobile vs Portable

There are advantages and disadvantages to mobile and portable equipment. To some degree, equipment selection is based on application, but there are more practical considerations that may come into play.

Both tracked and wheeled chassis offer producers portability, versatility and flexibility. Portable setup times have improved over the years, but it still has to be spotted, set up, have cables laid out and connected to external power. Depending on the equipment, this can take anywhere from a few hours, to several days. Mobile equipment sets up in minutes, not hours.

Track-mounted mobile equipment has a smaller footprint and is completely self-contained. It doesn&#;t require external power, so it&#;s able to access remote locations and sites where space is limited.
