Aggregate Screening Equipment
Definition and Purpose
Aggregate screens, also known as aggregate vibrating screens, are essential tools in the construction and aggregate industries. Their primary purpose is to separate and classify materials into different sizes and grades, ensuring that the final product meets specific standards and specifications. By removing unwanted materials such as fines and oversized particles, screens improve the efficiency and quality of the aggregate production process. This separation process is crucial for producing materials suitable for construction, road building, and landscaping, making screens indispensable in these industries.

How it works
Aggregate processing uses top of the line screening equipment designed for high-volume operations to separate materials into different sizes and grades. The process starts by feeding the materials onto the screen, often with crushers screens to produce finished products. These crushers aggregate screens, which can be horizontal, incline or aggregate vibrating screens, then vibrates to separate the materials into different fractions. Each type of crushers aggregate screens has its own mechanism and application so the materials are sorted accurately and efficiently. The separated materials are then collected and used for construction, road building and landscaping to meet the required standards and specifications.
The screening deck vibrates or uses gravity to move particles, separating it by size and shape. Larger materials, such as crushed stone, are captured by mesh screens while smaller particles like sand and gravel pass through the openings.
Aggregate screens are made from woven wires, a durable and flexible screening surface. The wires are woven in a grid pattern to form square openings of varying sizes. The opening size is determined by the application and the required particle size.
There are two types of aggregate screens: horizontal and inclined. An inclined screen uses gravity to help with the feed flow, commonly used for aggregate applications. Horizontal screens require more power but are good for low profile applications with limited height.
In operation aggregates are fed onto the screen and the equipment vibrates to pass particles through the squares. The larger particles stay on the screen surface and the finer materials pass through. This separation process produces the required amount to ensure consistency and quality throughout.
One of the benefits of aggregate screens is you can increase efficiency. You can sample products in a short time frame and save resources. You don’t need a lot of experience to operate aggregate screens but you do need to choose the right aperture size.
Choosing the Right Type
Choosing the right screen is key to getting efficient and effective aggregate screening. Here are some things to consider when selecting a screen:
-
Capacity: How much material needs to be screened. High capacity for large scale operations, low capacity for smaller projects.
-
Efficiency: The level of separation required will determine the type of screen needed. High efficiency screens for critical separation.
-
Product Quality: The quality of the final product will determine the screen choice. Make sure the screen can produce material to the required specs and standards.
-
Maintenance: Consider the maintenance required to keep the screen running. Low maintenance screens reduce downtime and operating cost.
-
Operating Cost: Consider the cost of running the screen, energy consumption, maintenance and replacement parts. Choose a screen that offers a good balance of performance and cost.
-
Screen Size: The size of the screen must align with factors such as material type, production requirements, and overall aggregate processing volume. Choosing the appropriate screen size can impact efficiency and suitability for specific screening tasks.
By considering these things aggregate producers can choose the right screen for their specific needs and applications.
Aggregate screening gives you:
-
Increased Production Rates and Screening Efficiency: Aggregate screening allows you to separate materials into different sizes and grades, reduce waste and increase production rates. Screening efficiency means materials are used effectively, maximise the output of the screening process.
-
Better: Aggregate screening ensures materials meet specs and standards so you get better products. By separating materials accurately the screening process improves the end product.
-
Less: Aggregate screening equipment is built to last so less maintenance and costs. So the equipment runs smooth with minimal downtime and contributes to overall screening productivity.
-
More: Aggregate screening can make you more profit by reducing waste, increasing production and producing better products. By optimising the screening process aggregate producers get better results and increase their bottom line.

Horizontal Screens
Horizontal screens are a type of aggregate screening equipment that use a horizontal motion to separate by size and shape. They are ideal for aggregate screening applications where high results is key. Horizontal screens excel with wet materials, separating even sticky or moist aggregates.
One of the advantages of horizontal screens is they produce high quality products with precise sizing. They remove contaminants and impurities from the stream so you get a cleaner and more consistent end product. That’s why they are a must have in the construction industry where high quality aggregate are required for building roads, bridges and other infrastructure projects.
Applications
Aggregate screens are used in:
-
Produces: To produce high quality aggregate materials like crushed stone, aggregate piles and sand.
-
Construction: To produce aggregate materials for building roads, bridges and other infrastructure projects.
-
Mining and Quarrying: To separate minerals and other materials from waste rock and impurities.
-
Recycling: To separate recyclable materials from waste and contaminants.
-
Landscaping: To produce decorative aggregate materials like gravel and mulch.
These applications show the versatility and importance of screens across different industries to produce high quality materials for many uses. Aggregate screens can handle various materials such as gravel and sand, making them essential in construction and mining applications.
In short aggregate screens are key to modern aggregate production, efficiency, reliability and sustainability. Buy top quality and maintain and you’ll see production rates, product quality and profit go up for aggregate producers. All the screeners agree!
