Screening Equipment
Upgrade Your Processing Operation with Our Screening Equipment
It's a fact. The right screens make all the difference in your aggregate processing operation, increasing your production efficiency—and ultimately, your profit. The bottom line is, you need screens. However, choosing the right ones can be complicated, especially if you're new to the rock, sand, gravel, or mineral processing industry.
Fortunately, here at Kemper, we've got decades of aggregate screening experience ready to help you set up an efficient circuit that will enhance your operation's overall performance.
Superior Screening Equipment for Your Needs
Aggregate Screening Equipment That Delivers Results
At Kemper, we supply heavy-duty screening equipment and engineer complete systems that keep your material moving and your operation productive. From retrofitting a screen into your existing plant to designing a new screening circuit, our team can help you select the right equipment for your operation.
How to Choose the Right Aggregate Screen
Selecting the best screening equipment starts with understanding your production goals and material specifications. Most screening setups rely on two primary configurations: incline screens and horizontal screens. Incline screens are often preferred for their efficient material flow and lower power consumption, while horizontal screens are ideal for tighter spaces or portable applications.
When evaluating your options, think about:
- The type of vibration: linear, elliptical, or circular motion
- Capacity and feed tonnage requirements
- Material moisture and gradation
- Available space and layout constraints
Why Consider Mobile Screening Equipment?
Mobile screening equipment is a smart choice for aggregate producers who need flexibility across job sites. These portable systems are designed for quick setup and relocation, making them an economical option for smaller production runs or temporary projects.
Whether you’re processing sand and gravel, crushed stone, or recycled materials, mobile screening plants can help you maintain consistent product quality wherever you work.

Types of Screening Equipment
There are screening applications in many aggregate industries, and the first step to implementing suitable screening systems for your production needs is choosing the right equipment. At the end of the day, screening is an art and a science. The art comes into play with the synchronizing of screen setups within a near-limitless number of applications. The science is stratification—the separation of large and small particles.
Deciding which type of screening equipment will work best comes down to understanding whether you need incline or horizontal screens. You'll also need to understand the main ways that screens move to achieve proper material stratification: vibrating movement in linear, elliptical, or circular patterns. There are also hi-frequency screens.
Incline Screens
No matter where you want to place them in your circuit, it's true that incline screens are typically the best bet. Inclines are best because they harness the power of gravity to reduce power consumption. As a result, the incline configuration has better capacity abilities when operating at similar speeds versus horizontal screens.
Inclined screen machines can vibrate in linear or elliptical patterns or in a circular motion. The latter tends to be preferred in continuous feed setups that screen large material, and incline screens can handle a high capacity of aggregate materials.
Horizontal Screens
If you're limited at your quarry or mine site by vertical clearance challenges that prevent the screen incline from being constructed at the proper angle—often about 20 degrees on the top deck—you will need a horizontal screen. Horizontal screens are commonly used in portable plants, or if you're feeding on a dredge in water-intensive operations.
Horizontal screens will typically vibrate with either linear motion or an elliptical motion. Both movement patterns are effective, but the linear—or straight-line—motion produces high G-forces to help dislodge material and propel it across the screen.

Other Considerations to Optimize Your Screening Operations
Besides considering whether you will use an incline or horizontal screen and their motion principle to provide your desired output, setting up a screening operation will require you to look at a few more decision points.
Dust Suppression
Screening is one of the most significant dust producers in most operations. Your screening equipment will need to incorporate screen-dust covers that physically block dust from escaping the machinery. You may also want to consider wet-dust suppression techniques depending on the material you're working with, especially if you're subject to OSHA's updated silica standard.
Feeders for Screens
You will need to understand whether your operation's production goals require the use of continuous or intermittent feeding tactics. It's a fact that the material to be screened can be fed from an intermittent-feed loading device like a wheel loader or a continuous-feed machine like a hopper or a conveyor. We can help you decide the most efficient method and design screening equipment to match your needs.
Selecting the Right Screen Media
Did you know that the primary maintenance concern with screening equipment is regularly replacing screen media? Your screening media type will typically be dictated by your screen equipment manufacturer's recommendations and by the kind of material you're producing.
Depending on the types of panels you're using for screening—wire cloth, urethane, or rubber—your time to replacement will vary. Screening media will last longer if it is used for sorting compatible types of aggregate material. Additionally, proper screen media support and tensioning will help maximize your screen media's life expectancy.
The best way to find the right aggregate screeners—as well as screen parts—for your operation is to work with a knowledgeable material handling solutions partner like Kemper.
