the complete guide to crushed stone and gravel

the complete guide to crushed stone and gravel

In this article, we are going to take a deep dive into the types of crushed stone and gravel, how they are made, and their basic applications. You may not be a quarry expert at the end, but you will understand the basics for your next concrete or hardscaping project!

Most crushed stone is produced in quarries and is crushed when machinery breaks up and crushes larger rocks. Instead of being shaped or formed naturally, such as in a riverbed or canyon, crushed stone is produced with man-made machinery and processes.

It begins with using a rock crusher in a quarry or site with plenty of large rocks. There are many types of crushers, but their main job is the same: Crush larger rocks into smaller pieces to be used for construction material.

Crushed stone is then passed through different screeners to be organized and stored in different piles according to their size. The screening process starts by removing larger stones, then medium stones, and eventually goes all the way down to the stone dust.

This screening is important because contractors need very specific types of crushed stone to complete different types of projects. For example, you dont want large stones in ready mix concrete, and you dont want stone dust in drainage systems.

After being sorted into different piles depending on the size of the stone, the stone is ready to be shipped from the quarry. Quarries deliver directly to job sites, to concrete plants, or to wholesale distributors who sell the stone through retail to customers.

Because large stones and quarries are hard on tires and require heavy metal, crushed stone was hard to make and transport until heavy machinery with tracks was developed. WW2 expedited the development of this machinery, and crushed stone began to be widely used in construction projects in the 1940s and 1950s.

Large-scale building projects, particularly in infrastructure like the Eisenhower Interstate System, helped usher in an era where crushed stone was used in almost every part of construction. Foundations, concrete, drainage systems, and roads were all needing large quantities of crushed stone.

An example of this often occurs when a road is being replaced or resurfaced. Many road construction companies are beginning to grind and crush the existing road as they remove it. This crushed road, which is essentially crushed stone, then becomes the base for the new road.

The exact amount of crushed stone recycling is unknown due to a lack of reporting. Much of the crushed stone is also recycled right on the construction site, especially with road construction, and this makes it difficult to measure.

The most common use for recycled crushed stone is as a base for roadways, especially when the old road can be torn up, crushed, and reused. Concrete blocks and bricks can also be crushed and recycled as a base.

Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water.

Metamorphic: Metamorphic rocks become changed through intense heat or pressure. Similar to clay hardening in an oven, metamorphic rocks become very hard and crystallized by intense or heat or pressure.

If you go to a creek or river, you see all types of rocks, both large and small. These larger rocks can be used for foundations or other building projects, but typically gravel is screened and only the smaller pieces are used.

Pea gravel: Pea gravel is some of the smallest gravel - typically or smaller in size. Pea gravel is often used in places like fish tanks, walkways, swimming pools, or other places where foot traffic occurs or small gravel is needed.

When thinking of construction, it is important to know what kinds of rock are ideal for specific applications. After all, if a rock type crumbles easily under pressure, you dont want to use it as a component in ready mix concrete or pavement.

Granite: An igneous rock that is durable and is easily polished. Because of the color, grain, and polishing ability; they are often used inside homes for countertops or on the outside of monumental or civic buildings. However, they can also be used on bridge piers and river walls.

Limestone: A sedimentary rock that is the most commonly used to make crushed stone in the United States. One of the most versatile rocks for construction, limestone is able to be crushed easily making it a primary rock used in ready mix concrete, road construction, and railroads. It is widely available in quarries across the country.

Slate: A metamorphic rock typically found in layers. Because it is easily mined and cut in these natural layers, it works well in applications requiring thin rock layers. Common examples are roofing tiles, certain types of chalkboards, gravestones, and some pavement applications.

Laterite: A metamorphic rock with a highly porous and sponge structure. It is easily quarried in block form and used as a building stone. However, it is important to plaster the surface to eliminate the pores.

Stone dust: This is the very fine dust, similar to sand, that is created as the stone is crushed. Stone dust is useful when tamping or packing stone, but it causes problems for applications where water needs to drain, such as behind a retaining wall.

Clean stone: If crushed stone is clean, it has been screened so the majority of the stone dust has been removed, but some dust is still mixed in. This is useful for the top layer of a stone driveway or other places where some minor compaction is not harmful.

Washed clean stone: This is stone that has been screened like clean stone, but then also washed to ensure there is no stone dust on the finished product. This is often used for drainage purposes, for ready mix concrete, or places that need aesthetic appeal, such as curbing or decorative stone.

Crushed stone: If you hear the generic crushed stone term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Or, if we were putting the base down for a patio, we want stone that compacts well and makes a strong base. Therefore, we want our stone to have stone dust, so we would call the quarry and order 2 crushed stone.

When putting down gravel in a flowerbed, make sure you start by laying down a quality landscape fabric, securely stake the fabric in place, and then layer the gravel on top of the fabric, usually 2-3 thick.

Stone dust compacts and hardens, especially when it becomes wet. Since drains need to always be open, it is important to keep stone dust out of drains. Therefore, construction projects needing drainage systems make sure they use only stone that has been cleaned and washed.

Crushed stone and gravel will continue to be a staple in construction, decoration, and industry for years to come. As recycling picks up, mining and quarries may slow down, but we will always need crushed stone in general construction and industry.

AG AGGREGATE is made up of inert material such as sand and gravel, crushed stone or slag, which when bound together into a conglomerated mass by a matrix forms concretes, mortars, plaster and mastics such as black top or macadam roads and asphalt road surfaces.

RKROCK, from which crushed stone, sand and gravel are made and the rock most suitable for making good aggregates is formed all over the world. See physical properties table for the various kinds of rocks and their physical properties.

SLSLAG is the air-cooled, non-metallic by-product of a blast furnace operation consisting essentially of silicates and alumina-silicates of lime and other bases which is developed simultaneously with iron in a blast furnace. Naturally, it is only available in those localities where pig iron is produced.

Do you need to process sand, gravel, minerals, rock, or other aggregate products and have not yet purchased or leased crushing equipment? Theres no questionyou need to work with a capable and professional material handling equipment design and engineering company dedicated to selling, renting, and installing the best new crushers for your needs.

However, if youre new to the aggregate processing industry, you probably have a lot of questions about rock crushers. As foundational material handling equipment in all plants, crushers need to coordinate seamlessly with screens, conveyor systems, and washing equipment.

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.

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 threeor even fourstations with a variety of crusher types.

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.

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.

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.

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 answer might be three to four if youre talking about setting up stations in a complete rock crushing plant. Those are the primary, secondary, and tertiary/quaternary/final reduction rock crushers, which we covered above.

Of course, there are also different styles of rock crushers. Compression-style jaw and cone crushers, for example, fit into the various stations in a crushing circuit (depending on factors like the sizes, varieties, and hardness of the rock you need to crush, as well as the necessary output).

The number of crusher types in terms of style and configuration can be more challenging to quantify, as there are lots of ways to customize rock crushers. However, youll find four basic designscone, jaw, gyratory, and impact crushersoperating within many crushing plants.

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 dont 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.

To learn more about jaw crushers, youll want to catch our previous blog post all about these tough pieces of material handling equipment and the most common questions operators have about jaw crushers.

Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky (whereas gyratory crushers are better at handling softer, dryer feeds). Their output will be a relatively cubical product, with a reduction ratio of about 6-to-1 through 4-to-1.

Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and 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 after they have already used a different type of rock crusher that produces a more elongated stone. This helps further shape the crushed material into a finer consistency with a more cubical nature.

Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rockslimestone and similaralong natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.

Drawbacks of impact crushers include their tendency to produce an excess of fine materials if used with softer rocks. Impact rock crushers can also require frequent part changes and can create a large amount of dust that can be an issue on some worksites.

Stationary plants have long been preferred because they feature a higher capacity and efficiency and lower production costs with easier maintenance. They also have historically featured a lower energy cost if you have on-site electricity, and no additional equipment is needed to move them from place to place.

Its true that portable material handling equipment already offers unmatched production flexibility. For instance, if you need to move your crushing plant more than once a year to multiple job sites, you are likely better off investing in portable equipment.

These self-contained plants are better suited to smaller projects and can be moved from project to project as necessary. They are often still not quite as efficient and have less capacity than stationary plants, but they can be more cost-effective in the long run if you have multiple projects in different areas.

Aggregate consists of manufactured crushed stone and sand created by crushing bedrock, and naturally occurring unconsolidated sand and gravel. The infrastructure created using aggregate is a major contributor to our current standard of living. Maintaining our lifestyle, passing that lifestyle on to our progeny, and supporting others to achieve developed nation status, will require huge amounts of aggregate. This chapter describes the aggregate industry and sustainable aggregate resource management, including the complex environmental, societal, and social issues associated with the exploration, mining, processing, transportation, and recycling of aggregate resources, and the reclamation of mined-out aggregate deposits.

5. The approving officials and the public must be convinced that the operation can take place without adversely affecting the environment or their lifestyle. In other words, the operator must be able to obtain a social license to mine.

6. The operation must be profitable considering all costs including: exploration, acquisition, permitting, operation, environmental controls, compliance with regulations, transport to market, and reclamation.

The production of aggregate involves extraction and processing of the raw material into a usable product, transport of that commodity to the point of use, and the reclamation of mined-out pits or quarries. The following is a general description of the production of natural aggregate.

You can get gravel by two methods: one is that excavating gravel from the sea or river bank and the other is that crushing waste stones like concrete waste, bricks, pavers, bricks, cinder blocks, demolition debris, etc., to get gravel.

With round and small in shape, people call this kind of natural gravel pea gravel. The size of pea gravels is at 1/8 to 3/8 with brown or brown and white in color. It is often used on path, driveway and playgrounds.

River pebble is round, colorful and with no angle, which makes it the best decoration for garden. Besides, the crushed river pebbles are often used as gravel and aggregate, and can mix with sand and cement.

The resources of natural gravel are limited and hard to get, which leads to the natural gravel increasingly high price, so crushed gravel from recycling waste stones is necessary. But if you are crushed gravel supplier, you need the following crushing equipment to recycle construction waste.

Waste concrete when being crushed and screened can be substitution of natural sand and natural gravel. These crushed gravels are often applied to produce ready-mixed mortar, cement admixture and concrete for construction building or driveway paving.

In order to better process building and demolition waste, you need mobile or fixed jaw crusher to reduces those large-sized stones. According to the various demands, the material can be screened into different sizes for different uses like producing concrete, mixing with asphalt.

Gravels mixes with sand, which can produce high-quality concrete. Gravel mixes with asphalt can produce asphalt concrete which is used to install a driveway. Besides, it is also can be used as road base, especially in rural areas and cold places.

Although natural gravels and crushed gravels are both applied to many industries, the limited natural gravel resources raise the price which is one of the reasons. There also exists other reasons:

As the stone crushing technology develops fast, it generates many different types of equipment combination forms for different construction recycling demands. The smooth process including crushing and screening ensures the multi-grade and high-quality of final gravel material.

Construction waste is never exhausted, and owns various kinds. Reusing these waste materials not only help cut down your cost, but totally is compatible with the concept of environment sustainable development.
