Vibrating Screen Technology

Granule Screening Machines

Granule screening machines precisely separate granules by particle size, ensuring consistently high product quality. During production, it often happens that individual particles do not meet the desired size specifications. Our machines reliably screen this heterogeneous material and prepare it optimally for the subsequent process steps.

As a manufacturer, we develop and produce high-performance, reliable granule screening machines for you—customized to your product and its properties.

SPALECK – Your No. 1 Partner for Pellet Screening Machines

As an experienced provider of conveying and separation technology for recycling as well as applications in the pharmaceutical, chemical, and food industries, we develop custom-designed granule screening machines to meet a wide range of requirements.

We work with you to develop the right screening solution—from planning and design all the way to the finished system—tailored precisely to your process.

At our SPALECK TestCenter, we analyze your specific requirements in detail. In doing so, we take into account, among other things, the properties of your material to be screened, the desired throughput, and the specific conditions of your plant. Upon request, we can conduct preliminary tests with your material to ensure optimal design.

Even after commissioning, we remain a reliable partner— offering comprehensive service, prompt delivery of replacement and wear parts, and flexible adjustments in the event of product changes or capacity expansions.

Example of a Granule Screening Machine in Use

Inspection Screening of Plastic Pellets

The video shows a granule screening machine in operation, used for inspecting plastic granules. It is clearly visible how agglomerates are reliably removed from the material and how the granules are evenly distributed across the screen deck. An integrated cleaning system prevents the mesh from clogging and ensures trouble-free operation.

For you as a customer, this means: consistent product quality, maximum process reliability, and optimal conditions for the further processing of your granules.

How the granulate screening works

How do pellet screening machines work?

To ensure that the pellet screening machine can achieve the best screening results, its vibration frequency, screening panels and inclination are optimally adapted to your screening material. At the start of the screening process, the raw material is fed into the granulate screening machine. Thanks to our special feeding technology, the granulate is fed very evenly onto the screening machine. The granulate is then separated into different fractions by the screening machine for granulates using vibrations and oscillations with the help of the screening panels. The screening result is the finest granulate, which you can use optimally.

We would be happy to advise you on how to make the best use of granule screening machines in your operation!

Granulate screening of different materials

How can the pellet screening machine be adapted to material changes?

As a manufacturer of pellet screening machines, we know that parameters can sometimes change in the pellet production process. It is therefore important to us that your pellet screening machine can also cope with these changing requirements. We design our screening machines for granulates in such a way that, for example, the screening surface can be changed quickly and easily when changing materials. This means that your employees can change screen linings very quickly on site. At the same time, maintenance is easy. Both minimize any downtimes during pellet screening and pellet production.

Efficient control screening for granulate processing

How is production-related oversize grain reliably separated?

Production-related oversize grain is reliably and precisely separated by the use of granulate screening machines. The granulate is guided over Screen decks that are precisely matched to the desired Particle size. Particles that are too large – the so-called oversize grain – remain on the screen and are discharged separately, while the dimensionally stable granulate passes through the further processing stage.

The vibratory movements used achieve an even Material distribution on the Screening area. This ensures high screening accuracy, clear separation precision and consistently high product quality. Even with demanding materials or high Throughputs, reliable Control screening is guaranteed.

For special requirements, such as plastic granulates, additional overlength separators can be integrated. These make it possible to sieve out elongated particles particularly efficiently and thus make a decisive contribution to Process reliability and quality assurance.

Advantages of Granule Screening Machines

What are the advantages of pellet screening machines?

  • Optimum adaptability of the pellet screening machine to your materials
