If you’ve never heard of a vibrating screen, you might be missing out on the way it can drive efficiency and accuracy within your business, increasing the quality of your final products. At VibraScreener™, we want to bring you the highest-quality equipment on the market, which is why we provide the information on what you need to know about mechanical screening before deciding it’s right for your company.

What Is Mechanical Screening?

Screening functions due to the probability that a particle of any given size will pass through an opening of a given size. Smaller particles are more likely to pass through, and as a particle increases in size, that likelihood drops.

A vibrating screen has various openings, and each one presents an opportunity for a given particle to pass through. Vibrating screens use one or more heavy-duty screen surfaces and a main frame, coupler, eccentric bock, motor and other components to pass particles through the screens.

Understanding mechanical screening efficiency will help you understand the process more thoroughly. While almost no equipment is 100% efficient in real-world applications, certain vibrating screens come close. The ratio of material that should pass through a given opening, and the material that actually does pass through defines screening efficiency. Fine particles have the highest efficiency because they are smaller and pass through easier. Near-size particles have a harder time and typically have lower efficiency because of it.

Why Use a Vibrating Screen?

Now that you know the fundamentals of vibrating screens, you should know why they’re used. When a company works with products that have a desired particle distribution or other characteristics, screening separates the material for proper size distribution and impurity elimination. Mixed materials that have different sizes and granularity values must be divided before the final distribution process. For these reasons, a mechanical screen is extremely useful in several industries, including mining, electricity, construction and chemical work.

What to Know About Mechanical Screening Before You Try It

You should know that different material and operating characteristics present unique challenges to each screening attempt. You need to make sure you have the right feed rate, bed depth and screen openings for the type of material you’re trying to feed through a screen. Then, consider the following about the material itself so you can find the right vibrating screen for the job:

  • Particle distribution
  • Moisture
  • Particle shape
  • Density
