Guide to Buying a Rock Crusher

Guide to Buying a Rock Crusher

If you’re thinking about adding a rock crusher to your arsenal, there’s a big decision in your future. From efficient yet portable models to massive workhorses, your rock crusher options vary widely. Let’s take a closer look at buying a rock crusher and how to make the most of this investment.

The Importance of Choosing a Rock Crusher

Before we get too far into the details, consider what you’ll get out of your rock crusher. These machines are excellent additions to many job sites, as they can help mitigate the skyrocketing costs of raw materials and support more eco-friendly construction practices — a win-win in the bid process and addition to your bottom-line profitability.

Rock crushers can convert old, unwanted materials, such as concrete, granite, asphalt, limestone and basalt, even glass into new base materials for further building. They often reduce or eliminate the need for raw materials. When you reuse old concrete or process stone, you save on costs through:

  • Raw material requirements: Concrete and masonry materials have jumped 15% in price in 2023 alone. A rock crusher allows you to save on the costs of new materials by replacing them with recycled ones, giving you more control over project costs.
  • Delivery costs: Getting material on-site can be expensive, particularly in rural locations. You can reduce or eliminate this cost by producing the material on the job site.
  • Disposal costs: Getting rid of old materials often requires costs such as landfill tipping fees and hauling fees. You don’t need to dispose of reused materials, so you can say goodbye to those exploding costs. If you pay a lot of disposal or tipping fees, a rock crusher could pay for itself very quickly!
  • More competitive bidding: Using recycled materials can make your bids more competitive through reduced costs and eco-friendly building practices, helping you earn more profitable jobs.
  • Sold materials: Even if you can’t use your recycled materials in a certain job, you can always resell them to make additional profit.

Aside from costs, rock crushers also help the planet by keeping recycled materials out of landfills and contributing to Leadership in Energy and Environmental Design (LEED) certification. Concrete is the most recycled material on earth! Understanding the advantages of rock crushers can help you better align your purchase with your goals. Whether you’re after a cost-saving measure, an eco-friendly tool or a mix of both, a rock crusher is a great pick.

 
Get to Know Our Five Types

What Are The Types Of Rock Crushers?

Now that you know what they can do, it’s time to figure out what style will best fit your workflow. Rock crushers come in a few different options, with crushing mechanisms designed for various processing stages. These stages include primary, secondary and tertiary or final reduction crushing.

In the primary crushing phase, the rock gets reduced to a small enough size for the secondary crusher, which further reduces the material to match the requirements of the tertiary or final crusher. The tertiary or final reduction crusher refines and shapes the material to its end product. You’ll find some overlap in what types of crushers are used at which stage.

What Is A Jaw Crusher?

1. Jaw Crushers

Jaw rock crushers use powerful compressive forces to break up the rock between two opposing jaw plates. They are the most common crusher used in the primary stage. They work on many kinds of materials and tend to produce less dust. Their output produces sharp angles and edges on the material often preferred by engineers for their gripping and setting strength. The are also the best crusher style to handle rebar and wire in concrete.

What Is An Impact Crusher?

2. Impact Crushers

Impact crushers come in vertical and horizontal varieties. Vertical shaft impactors (VSIs) and horizontal shaft impactors (HSIs) use impact forces, utilizing blow bars (rotors) spinning at high rpm’s and throwing the material against the wall of the crusher to break them apart. They produce a more rounded material and are the primary crusher type used to process soft, gummy asphalt.

You’ll typically find impact crushers used in primary, secondary, and tertiary or final crushing, as they can help shape the rock and produce fine materials. They work well with abrasive rocks. Impact crushers can create significant dust, so you may need to take caution on some job sites. Their inherent design is not the best for concrete with wire and rebar. Vertical Shaft Impactors (VSI’s) are also know as Sandmakers for the small size material they can produce.

What Is A Cone Crusher?

3. Cone Crushers

A cone crusher is a large drum with a cone in the middle like an upside-down funnel surrounded by a concave ring on the wall of the drum. The cone moves inside the drum in an elliptical grinding motion. As the rock moves down the edges of the drum, it gets broken up into smaller pieces as the gap between the cone and wear ring on the wall narrows.

Cone crushers can accommodate medium-hard and hard materials, and they’ll work with some abrasive feeds. They can produce smaller materials, making cone crushers a popular choice for secondary and tertiary crushing.

What Is A Rock Crusher Plant

4. Rock Crusher Plants

A portable rock crusher plant includes different types of rock crushers for an all-in-one solution. You can take these rock-crushing plants on-site to crush and screen materials to finish the process with one piece of equipment. They include multiple crushers, screeners, and conveyor recycle systems all on one chassis.

What Are Additional Types Of Crushers?

5. Additional Crusher Types

In addition to the three main types of crushers above, there are many other types of crushing machinery more specialized and/or variations on the above. There are roller mills with pins or wheel type rollers, vertical roller mills, hammer mills, and ball mills which are large drums with steel or ceramic balls as grinding media that can produce material down to 400 mesh (think baby powder fineness). These are all specialty type material reducing machinery almost exclusively used in stationary plants for reduction down to very fine material.

Portable vs. Mobile vs. Stationary Rock Crushers

Rock crushers come in portable, mobile, and stationary options. Portable crushers refer to machinery on trailers with wheels for the maximum on portability. Mobile crushers are crushers on tracks, like models with built-in crawlers, and are valued due to their mobility once on site, especially in larger crusher machinery. They require prime moves to get them to the work site and sacrifice a bit in portability. Stationary crushing equipment is machinery that stays in place once commissioned like in traditional quarries and aggregate producing plants. Though we can provide even the largest crushing plant design in the world, Senya Crushers specializes in our ultra-portable MICRO rock crushers, small enough to be towed with just a pickup truck! They’re perfect for job sites with limited space, smaller amounts of materials to process, or remote sites though they are workhorses designed to handle larger, more permanent crushing jobs as well.

For many small and mid-sized projects, our ultra-portable MICRO rock crushers offer all the benefits of a larger machine alongside extensive flexibility, portability, not to mention affordability. They move the crushing plant to the rocks, bringing crushing capabilities on site. If you need larger processing capacity, mobile systems and portable systems alike can accommodate higher capacities as we builder crushers with a large range of output capacities. Many mid-sized portable options offer the best of both worlds. We also offer 3 in 1 and 4 in 1 systems incorporating primary and even secondary crushers accompanied by a screen plant on a single chassis able to be pulled with a prime mover.

Selecting the Best Rock Crusher for Your Needs

With your newfound knowledge of rock crushers, how do you know which one is right for your work? Start by considering the following aspects:

  • Cost and savings potential: Of course, your budget will affect what kind of rock crusher you can get. Consider how much money you stand to save with a rock crusher by calculating disposal costs and new material spending from previous and future projects. Remember, high-quality equipment can offer a higher return on investment through efficiency and performance benefits.
  • Operation and Maintenance costs: With our diesel over electric crusher design, our MICRO Crushers offer almost negligible daily operation costs. No hydraulics and the associated high maintenance costs, especially in the rough crushing environment, our Senya 5 runs all day long on less than $50 in fuel. Electric motors powered by diesel generator design is unmatched in operational cost efficiency.
  • Type and amount of stone: Determine what type of material you work with the most. Some rock crushers work better with materials of certain sizes or hardness. For instance, a jaw rock crusher might be better for larger materials, while crushing rocks with a VSI can help refine smaller-sized materials.
  • Mobility requirements: Do you want to move your crusher around a lot? If your job sites change frequently, a MICRO crusher offers the most portability and flexibility, so you can use your crusher as much as possible. Otherwise, consider what equipment you have to move your crusher or crushing plant.
  • Existing equipment: With all crushers, you will need a loader or backhoe to feed the pieces of concrete, stone, or material into the machine. Depending on your equipment, you may need to consider either different models or additional equipment.

Which Type of Crusher Is Best?

The best type of rock crusher will depend on your application and operations. MICRO or small rock crushers are ideal for small and mid-sized contractors who move job sites often and need general-purpose crushing capabilities. Portable crushing plants can accomplish comprehensive crushing on-site for an end-to-end solution. Although they come assembled, they aren’t quite as easy to move as MICRO crushers and may require larger transportation equipment. Stationary rock crushers can accomplish primary, secondary or tertiary crushing with high efficiency and performance. Many crawl crushers fit these demands, too, with the added benefit of easy transportation. The right rock crusher for your work depends on many factors, but you can always contact the pros at Senya Crushers for support.
