5 Tips to Improve Aggregate Screening Efficiency

What are the tips to improve aggregate screening efficiency?

  1. Choose the right screening media
  2. Utilize the right mobile screen size
  3. Configure the settings
  4. Ensure proper feeding
  5. Maintain the screening equipment


Aggregates such as crushed stone, minerals, gravel, sand, or construction waste need to be screened to produce sellable products. But it is not always an easy and problem-free process. There are times when you will encounter issues and challenges, but with the right strategies, you can effectively minimize these situations. If you’re interested, here are some tips to improve aggregate screening efficiency.

But first, let’s define what screening efficiency is. It measures how much of the aggregate is properly separated during the screening process. It’s a good idea to aim for as close to 100% efficiency as possible, but getting around 90% and above is considered an exceptional result for many organizations.

Choose The Right Screening Media

Before you employ the strategies for better screening efficiency, you first need to look at the equipment you’re using. To achieve the highest production efficiency, you need to make sure that your screening device matches your aggregate.

For instance, you might not be using the right screening media for your application. It’s one of the critical aspects that managers overlook when it comes to maximizing production efficiency.

Wire cloth is affordable and has a shorter lifespan, but it’s a great choice if you need a higher percentage of open area. Rubber ones might not have as much open area as wire cloth but are better suited for high-impact applications. For wet applications, consider polyurethane screen media.


Utilize The Right Mobile Screen Size

Next, it’s also essential to match the mobile screen size to the material you’re processing for the best results. Different aggregates have different separation rates. First, you need to consider the screen opening. This is because there’s a chance that the materials can cause the congestion of the screening surface. When this happens, the particles can’t pass through as expected.

After that, look at the particle distribution. The more material needs to pass through the screen, the larger the mobile screen should be. You also need to factor in the screen length. It’s a good idea to increase the length, so you can have a longer time for materials to pass through the mobile screen.


Configure The Settings

To achieve the maximum efficiency of your screening equipment, you need to put the effort into adjusting the settings. For example, if you’re using a vibratory screen, it’s best to keep the vibrating motion at a steady pace — neither too fast nor too slow. Otherwise, this could make it difficult for the particles to pass through.

You also need to adjust the inclination angle of the screen surface. Ensure that it complements the frequency and direction of the vibration.

Other than these, you also need to consider the terrain if you’re using mobile screens. It’s not always the case that the surroundings will be level when you’re screening remotely. If needed, readjust the angle of inclination and ensure that the screen is level. This way, you can maximize the use of the entire screen deck width. Fortunately, mobile screens are easy to move.


Ensure Proper Feeding

Ensure Proper Feeding

The feeding method also affects how efficient the screening will be. If you notice that the particles are incorrectly separated and sized, then it’s worth looking at this aspect. For example, poor results could be caused by improper distribution of material or a fast feed flow.

Other than that, look at how the material performs. Are the aggregates jumping around or being thrown out of the screen? In this case, the amplitude is high.

If you’re using a vibrating screen, it’s best to feed the material into the feed box or impact area. Make sure that the aggregate is spread as wide as possible, so the full width and total screening area are maximized.


Maintain The Screening Equipment

If you’ve done all the steps above, but the screening efficiency didn’t improve much, then it might be because of a lack of maintenance. Like other equipment in your material processing site, your screening device also needs preventive maintenance. By being proactive in taking care of your machinery, you can reduce unexpected downtimes — which can affect production efficiency too.

Check your screening equipment regularly to remove dirt and other contaminants. These particles can influence the movement of the screen. Ensure that the screen media is in good condition and replace it if needed. Other than these, you can establish a maintenance routine by consulting your manufacturer’s manual.
