Gravel Screening Basics
What Is Gravel Screening
Gravel screening helps you sort rocks by size. Special machines do this job. These machines include vibrating screens, trommel screens, disc screens, and flip-flow screens. They separate gravel, sand, and crushed stone into even sizes. At ANPENG, we make screeners that work hard and last long.
- Gravel screeners use different ways to move and sort rocks.
- They help you remove pieces you don’t want and keep the right size.
- You can use these machines for building, landscaping, and making aggregates.
- This process gives you the same quality every time.
Screening puts particles on a surface and sorts them. The screen keeps or lets go of pieces based on their size. This helps you get the exact material you need for your project.
Why Screen Size Matters
Picking the right screen size is very important. The mesh holes in your screen decide what goes through and what stays out. Big holes let large pieces pass. Small holes catch tiny pieces.
Tip: Always pick a screen size that fits your project. Using the wrong size wastes material and gives bad results.
The right gravel screen size makes your final product better and more even. For example, screened aggregates can make concrete up to 15% stronger than unscreened ones. That’s a big change for any building job.
Screening Efficiency
You want screening to be quick and correct. Good screening gives you more useful material and less waste.
- Gravel screeners sort rocks by size, so you meet job needs.
- The process removes pieces that are too big or too small.
- Controlling size gives you steady quality and better results.
Screening plants are made to handle lots of material and need little fixing.
Common Gravel Screen Sizes
Stone Dust and Screenings (<2mm)
Stone dust and screenings are the smallest gravel sizes. These materials are less than 2mm wide. People call them stone dust or screenings. At ANPENG, customers use these tiny particles for many jobs. They work well under pavers and concrete blocks. Stone dust helps hold bigger crushed stones together. It fills spaces in patios, walkways, and wall bases. Sometimes, it mixes with bigger rocks and is called “crusher run.”
Here’s a simple chart about what they are and how people use them:
| Characteristic/Use | Description |
|---|---|
| Size | Less than 2mm |
| Common Name | Screenings or Stone Dust |
| Uses | Used for pavers and concrete blocks, makes things stronger, holds bigger rocks together, fills gaps in patios, walkways, and wall bases. Sometimes called ‘crusher run’ when mixed with bigger rocks. |
- You should not use stone dust or waste screenings for every job. Too much fine material can go through the No. 200 (0.075 mm) screen. This can cause problems with water draining or keeping things stable.
#8, #57, #67 Stone Sizes
These gravel sizes are seen in many places. They are very popular for lots of projects. At ANPENG, we help you choose the right stone. Each size is good for different things.
| Stone Size | Typical Applications | Properties |
|---|---|---|
| #8 Stone | Mixed into concrete and asphalt, used for decoration | Small size (3/8 inch), makes smooth surfaces |
| #57 Stone | Base for asphalt/concrete, under pavers | Medium size (about ¾ inch), helps with water flow and strength |
| #67 Stone | Finer finish, thin concrete layers | Like #57, packs well for solid coverage |
- #8 stone is good for mixing into concrete and asphalt. It also works for decoration. Its small size makes smooth surfaces.
- #57 stone is great for base material in asphalt and concrete. It works well under pavers. This medium size helps with water flow and keeps things strong.
- #67 stone gives a finer finish. It is good for thin concrete layers. It packs well for solid coverage.
Sieve Sizes: 1/8″, 3/8″, 1/2″, 3/4″, 1″
You might wonder how gravel sizes match screen mesh sizes. Gravel is sorted by passing it through screens with different mesh sizes. The most common mesh sizes are 1/8″, 3/8″, 1/2″, 3/4″, and 1″. Each size is used for a special job in building or landscaping.
For example, gravel that goes through a 1-inch screen but stays on a 3/4-inch screen is called 3/4-inch to 1-inch gravel. This helps you know what you are getting for your project. Good screening makes sure you get the right stone for your job, whether you need water to drain, a strong base, or a smooth top.
At ANPENG, we make screens that sort stone fast and correctly. You get the right gravel sizes every time. Your work goes faster and looks better.
Aggregate Size Ranges
When you look at gravel screen sizes, you’ll see that each type of stone fits into a certain size range. These ranges help you pick the right material for your job. At ANPENG, we use advanced screen mesh sizes to sort stone and crushed stone quickly and accurately.
Here’s a simple table showing the most common aggregate size ranges:
| Material Type | Size Range |
|---|---|
| Sand | 0.0625mm to 2mm |
| Gravel | 2mm to 75mm |
You might wonder how these ranges are set. The answer is in the way we test and sort stone. We use a screen with different mesh sizes to separate crushed stone and gravel sizes. The aggregate sieve analysis test is key. You pour the material onto a stack of screens, each with smaller holes than the last. As you shake the stack, smaller pieces fall through, and bigger pieces stay on top. This test shows you the gradation, or mix of sizes, in your stone.
Tip: If you want a strong base, choose dense graded aggregate. This type has a mix of stone sizes, so it packs tight and stays solid. If you need good drainage, pick open graded aggregate. It uses bigger crushed stone with fewer fines, letting water flow through.
Aggregate gradation matters for every project. You can choose:
- Dense graded aggregate (DGA): Many stone sizes mixed together. Great for road base and foundations.
- Uniformly graded aggregate: Stone pieces are almost the same size. Good for decoration or special concrete.
- Open graded aggregate: Mostly large crushed stone, not much fine material. Perfect for drainage jobs.
When you pick gravel screen sizes, think about what you need. Do you want a tight-packed base, smooth finish, or fast drainage? The right screen mesh sizes help you get the best stone for your project. At ANPENG, we design screens that sort crushed stone and gravel sizes with speed and precision. You get the right material every time, whether you need sand, gravel, or larger stone.
Gravel Size Chart and Applications
Gravel Size Chart Overview
When you look at gravel for your project, you want a clear way to compare sizes and uses. That’s where a gravel size chart helps. At ANPENG, we use the gravel size chart every day to help you pick the right material. You can see the most common grades, their size ranges, and what each one does best.
Here’s a quick chart to guide you:
| Grade | Size Range | Description | Common Applications |
|---|---|---|---|
| #3 | ½″–2″ (12–50 mm) | Coarse, heavy, angular stones | Road bases, railroad ballast, stabilization, drainage |
| #8 | ⅜″–½″ (9.5–12.5 mm) | Small, pea-sized stones | Landscaping, walkways, drainage, concrete mixes |
| #10 (screenings) | <¼” (<4.75 mm) | Fine stone dust | Base layer for pavers or bricks, pathways, asphalt, compacted fill |
| #57 | ~¾″ (19 mm) | Clean, angular gravel; most commonly used | Driveways, concrete mixes, French drains, general construction |
| #411 | ~¾″ (19 mm) down to fines | Blend of #57 and dust | Driveway, paths, parking areas |
| #21 (A or B) | ~¾″ (19 mm) down to fines | Dense-grade aggregate (DGA); similar to #411 | Road and driveway bases, foundation, compactable fill |

You might wonder how each gravel size fits into your project. At ANPENG, we help you match the right grade to your specific applications. Here’s how the gravel size chart connects to real jobs:
Landscaping
You want your garden or yard to look great and last long. Smaller stones like #8 and pea gravel work best for landscaping. These sizes make smooth paths, fill garden beds, and add color around trees or patios. You can use screenings for a base under bricks or pavers. The gravel size chart shows you which grades give you the look and feel you want.
- #8: Paths, flower beds, around foundations
- Pea gravel: Garden paths, decorative borders
- #10 (screenings): Under pavers, patios
Drainage
Good drainage keeps your property safe and dry. Larger stones like #3 and #57 help water flow away from buildings and roads. You can use these sizes in French drains, under driveways, or behind retaining walls. The gravel size chart makes it easy to pick the right grade for drainage applications.
- #3: Drainage ditches, stabilization
- #57: French drains, under concrete, driveways
- #8: Light drainage, walkways
Note: If you use the wrong size, water can pool or run off too fast. Always check the gravel size chart for drainage jobs.
Road Base
Strong roads and driveways need a solid base. Coarse gravel like #3, #21A, and #411 packs tight and stays put. These sizes support heavy loads and resist shifting. At ANPENG, we recommend checking the gravel size chart before you build a road base. You want the right mix for strength and stability.
- #3: First layer for road base
- #21A/#411: Compactable fill, driveway base
- #57: Top layer for driveways
Decorative Gravel
If you want to add style to your yard or business, decorative gravel is the way to go. Pea gravel and #8 stone look smooth and colorful. You can use them in garden beds, walkways, or around water features. The gravel size chart helps you pick the best size for your design.
- Pea gravel: Garden paths, accent areas
- #8: Decorative borders, flower beds
- #10 (screenings): Fine finish for patios
Tip: Decorative gravel comes in many colors and shapes. Use the gravel size chart to match your style and needs.

Choosing Gravel Screen Sizes
Project Requirements
When you start a new project, you need to think about what you want your gravel to do. Are you building a driveway, a garden path, or a drainage system? Each job needs a different screen size. At ANPENG, we help you match the right screen to your project. You want to pick a screen that gives you the best results and saves you time.
Here are some practical tips for choosing the right screen:
- Look at the size of the gravel you need. Bigger projects, like road bases, use larger screens. Smaller jobs, like landscaping, need finer screens.
- Check the types of gravel your project requires. Some jobs need a mix of sizes for strength, while others need uniform pieces for looks.
- Think about the uses for each type. For example, drainage needs open spaces between stones, so you want a screen that lets bigger pieces through.
Tip: Always match your screen size to your project’s needs. This helps you avoid waste and keeps your work on track.
Material Type and Moisture
The type of material you use can change how you pick your screen. Some types of gravel have more clay or sand mixed in. Wet material can stick together and block the screen. At ANPENG, we know that moisture makes screening harder, especially with fine gravel.
Here’s a table to help you see how material and moisture affect your choice:
| Material Issue | What to Watch For |
|---|---|
| Wet or sticky gravel | Can clog screens, slows down work |
| Fine gravel | Needs smaller mesh, but can cake when wet |
| Clay content | May blind screens, needs rugged panels |
If your gravel is wet, you need a screen that prevents caking. You may want to use panels or grates that resist clogging. For high moisture, choose screens with larger holes or special coatings. This keeps your screening efficiency high and helps you get clean, sorted gravel.
Note: Always check your material before you start. If it’s wet or sticky, adjust your screen type to avoid problems.
Throughput Considerations
You want your screen to handle the right amount of material. If you pick a screen that’s too small, you slow down your work. If it’s too big, you might miss fine pieces you need. At ANPENG, we design screens to match your workload.
Think about these factors:
- Screen size and mesh options: Larger screens process more gravel per pass. If you need versatility, look for models with multiple mesh sizes.
- Material capacity: Match your screen’s capacity to your expected workload. This helps you avoid bottlenecks.
- Quick screen changes: Some screens let you switch mesh sizes fast. This is great if your project needs different types of gravel.
Tip: Always check your screen’s capacity before you start. This keeps your project moving and helps you get the right types of gravel every time.
Choosing the right screen size means thinking about your project, your material, and how much you need to process.
Mistakes to Avoid with Gravel Sizes
Choosing the right gravel size can make or break your project. At ANPENG, we see a few mistakes pop up again and again. If you want your screen to work well and your results to last, watch out for these common issues.
Wrong Mesh Size
Picking the wrong mesh size for your screen can cause big problems. If you use a mesh that is too large, small stones will slip through. This can leave you with uneven layers or weak spots. If your mesh is too small, the screen will clog fast. You will spend more time cleaning than working.
Here are some things to keep in mind:
- Always match your screen mesh to the size of gravel you need.
- Check the common uses for crushed stone before you start. This helps you pick the right mesh for your job.
- Test your screen with a small batch first. This way, you can spot problems early.
Tip: If you notice your screen is not sorting gravel as expected, stop and check your mesh size. A quick fix now saves hours later.
Ignoring Environmental Factors
You might think all gravel works the same, but the environment changes everything. If you ignore these factors, your project can fail.
Consider these points:
- The size of gravel particles affects how stable and strong your base will be.
- Good particle distribution gives you a compacted base that lasts longer.
- The composition of your gravel changes how well water drains and how much erosion you get.
If you skip these checks, you risk:
- Weak spots and poor structural integrity.
- More repairs because of erosion or shifting gravel.
Note: Always look at your site’s needs before picking a screen size. Wet areas, slopes, or heavy traffic need special attention.
Maintenance Oversights
Even the best screen will fail if you skip maintenance. At ANPENG, we recommend a few simple steps to keep your screen running smoothly.
- Inspect your screen often. Look for worn parts or damage.
- Clean and lubricate all moving parts. This keeps everything working well.
- Fix or replace broken pieces right away.
- Adjust your screen angle if you see material building up.
- Use a ball tray to stop fine gravel from blinding the screen.
- Try a heated screen deck if you work with wet or sticky material.
Regular care keeps your screen efficient and your gravel sorted right. You save time and avoid costly breakdowns.
If you avoid these mistakes, your screen will last longer and your projects will turn out better. At ANPENG, we help you pick the right screen and show you how to care for it, so you get the best results every time.

- Monitor your operation in real time. Check particle size often to keep quality high.
- Train your team. Good training means better handling and less downtime.
Regular maintenance keeps your screen running longer and helps you avoid costly repairs.
Adjusting for Material Type
Different materials need different approaches. You can’t use the same screen for every job. At ANPENG, we help you match your screen to the material you’re working with. Take a look at this table for common choices:
| Material | Common Screen Sizes |
|---|---|
| Rock | 1″, 2″, 3″ |
| Gravel | ¾”, ½”, ⅜”, <¼” |
| Asphalt | 1″, ½”, ⅜” |
| Dirt | ½”, ¾”, 1″ |
You should always pick a screen size that fits your material. Think about moisture, gradation, and how sticky or abrasive the material is. If you work with wet gravel, you might need a screen with larger holes or special coatings. For dusty or dirty material, choose a screen that handles fine particles well.
The right screen system makes your job easier and helps you get the best results. Always consider the type of material and your production goals before you start.
