From our homes to our roads, schools, and pathways, almost every building structure we come across is made using aggregates.
Aggregates have become essential within the construction and landscaping industry. But before they can be used in construction, they first need to be processed and refined.
During aggregate processing, different raw materials pass through multiple treatment stages to produce high-quality aggregates. These processed aggregates of different sizes, strengths, textures, and shapes can then be used to build almost anything.
How does aggregate processing work?
In this article, we’ll explore the steps involved in aggregate processing, and how each step helps us create the final aggregates we use to build strong and long-lasting structures.
What Are Aggregates?
Aggregates are a combination of quarried or mined materials that are broken down into different sizes for use in construction and landscaping. They’re one of the basic requirements of any construction project.
There are three main types of aggregates: natural, manufactured and recycled aggregates. Some popular examples of aggregates include materials like sand, gravel, subbase, and carrstone. These play an integral role in creating strong foundations for different types of construction and landscaping projects.
Aggregates are also used to hold cement and other materials together for high-quality and long-lasting results. They also help improve drainage.
To obtain and maintain the highest quality of performance, all aggregates need to be processed before they’re put to use. While proper, comprehensive aggregate processing can take patience and time, the results are worth the effort.
How Does Aggregate Processing Work?
Aggregate processing involves many different steps, depending on the project requirements and specific aggregate materials. During processing, aggregates are broken down and screened to maintain their desirable qualities and separated into specific categories.
Let’s take a closer look at some of the key steps involved in aggregate processing:
Aggregate Extraction
The first step of aggregate processing involves extracting aggregates from their source, such as a quarry or a mine. At this stage, the aggregate materials are removed from the Earth with heavy machinery.
Aggregate extraction is also carried out at building sites. This is so that broken materials from, for instance, demolished buildings or old roads, can be recycled to form new aggregates.
Aggregate Crushing
More often than not, aggregates obtained from extraction are much larger than the final desired product. Through the process of aggregate crushing, these large pieces are broken down into smaller particles. This is done with the help of heavy machinery, like jaw crushers and impact crushers.
Aggregate Screening
Screening is the stage of aggregate processing where the crushed aggregates are separated into different categories based on their size. Depending on the type of machinery used, the source materials, and the desired type, aggregate screening may be carried out in multiple stages.
Some Other Important Steps in Aggregate Processing
Aggregate processing involves multiple steps. Aside from the key steps mentioned above, there are a few additional steps involved in the process.
Let’s examine some of the other important steps in aggregate processing:
1) Conveying
Conveying refers to the process of transporting aggregate materials between the different steps of processing.
It’s carried out using conveyors, automated systems that transport materials and establish proper connections between the crushers, screens, and piles of aggregates.
Instead of having loading machines or employees move the materials manually, conveyors provide an efficient solution to transport the materials to where they’re needed. Conveying also helps control the flow of materials to avoid overwhelming the crushers and screeners.
2) Washing
During aggregate processing, certain aggregates may need to be washed to remove impurities or unwanted materials. In this stage, water and various cleaning agents are used to eliminate dust, dirt, and other contaminants.
3) Sorting and Storage
After the aggregates are processed, they need to be sorted. During this stage, all the processed aggregates are categorised according to size, shape, or texture, and stored in silos or stockpiles. Once this step is complete, the aggregates are ready to be transported to be used in various projects.
