Top-notch quality all year round
This SPALECK 3D COMBI screening machine was specially designed for the production of high-quality compost. It precisely separates compost, biomass, and organic matter by size. What makes it special is that this compost screen delivers very precise screening results regardless of moisture content, season, or variations in material. This ensures the highest level of reproducible quality, produced in a highly cost-effective manner.
The Best Compost Quality—No Matter the Season
In the video, Christian Olde Bolhaar explains how switching from a drum screen to a 3D COMBI compost screen marked a decisive step in optimizing his process. Thanks to SPALECK tension shaft cassettes and, now, SPALECK AutoCLEAN technology, it achieves the highest compost quality year-round—while also optimizing production processes. You, too, can save yourself the hassle of cleaning.

More InformationThe screening quality is extremely important when screening compost and organic material. If it is too imprecise, your company will lose money, as high-quality fine humus is sieved out with the oversized grain. In addition, there is a risk that long grains will end up in the substrate and the compost quality will drop significantly. Your new 3D COMBI compost screen actively prevents this and enables the best screen qualities for you and your end customers.
Organic raw materials are often subject to enormous fluctuations in terms of moisture and composition. The 3D COMBI compost sieve from SPALECK masters these changing requirements. This allows you to adapt your screening machine easily, quickly and flexibly. In addition, unlike other brands, the cleaning effort and reconfiguration of the sieve settings is minimized.
All the Benefits at a Glance
Maximum benefit for your screening result
Together with our customers, we develop screening machines tailored to their specific materials. We cordially invite you to screen your organic material and compost at the TestCenter. That way, you can be sure today that you’ve found the solution for tomorrow.
Our team would be happy to advise you on the use of SPALECK screening machines in compost production. We’d be happy to show you our client references and best-practice case studies.
SPALECK compost screening machines are ideal for:
Thanks to our ModularDESIGN+ principle, the screening machines are optimally tailored to your material. This ensures excellent screening results even with varying input materials—for the highest product quality and the cleanest screening results for organic materials such as compost, growing media, biomass, mulch, yard trimmings, and green waste, free of coarse particles.
The 3D COMBI compost screen has been specially developed for processing and screening organic materials such as compost, biomass, green waste, etc.
This compost screening machine enables the cleanest and most accurately separated screen cuts in biomass processing.
Thanks to user-friendly and innovative screening technology, very consistent screen qualities can be produced all year round. With this screening machine for compost and organics, you are therefore independent of the weather and season.
The screening machine is also easier to maintain and clean than mobile screening machines for compost processing, for example. The SPALECK 3D COMBI screen for compost is therefore uncompromising in terms of outstanding screen quality, high screening capacity and optimum user-friendliness.
Of course, in addition to screening machines for recycled fertilizer, we also offer screening machines for synthetic fertilizers.

The 3D COMBI compost screening machine is optimized for screening organic materials such as compost, biomass, and green waste. Depending on the input material and the country of use, it can be equipped, for example, with technology to protect against glass breakage or to stabilize the tension wave cassettes when material moisture levels fluctuate. We would be happy to advise you on this matter.
Yes, AutoCLEAN can be retrofitted to an existing SPALECK screening machine. We can quickly check whether your specific machine is suitable for this based on the machine number. For more information, visit the AutoCLEAN screening technology landing page.
Yes, as a compost producer, you can thoroughly test SPALECK screening technology for compost production before making an investment. And it’s free. Extensive material testing with your material helps determine and configure the optimal screening technology for your compost production. This way, you can see in advance of making the investment what high-quality compost can be produced.
Compost producers, such as Olde Bolhaar from the video, are switching to a specialized compost screening machine, in part because of its highly precise screen sizes and consistently high compost quality, even when material conditions vary. In addition, they benefit from minimal cleaning requirements for the screening equipment.
The effort required to clean screening machines and screen media during compost production can be reduced and minimized using AutoCLEAN screening technology or, for example, tension shaft cassettes. These are designed for material that is difficult to screen, damp, or sticky, respectively. AutoCLEAN technology keeps the screen mesh moving during compost production by applying additional, adjustable vibration, thereby preventing buildup and clogging.
SPALECK screening machines for compost production deliver consistent screening results even with varying moisture content and material composition, thanks to their flexibly adjustable screening technology configuration. The screening machine can be adapted to the various and changing properties of the organic feedstock. Examples of this include the use of tensioned-shaft cassettes or the SPALECK AutoCLEAN screen lining. This ensures that compost of a very consistent quality can be produced year-round.
Precise screening improves product quality in industrial compost production by separating the high-quality fine fraction from oversized particles and keeping long pieces out of the target fraction. If valuable fine particles are discharged along with the oversize material, valuable and highly usable material is lost; if long pieces end up in the finished substrate, they reduce its quality and can cause filled bags to tear. The 3D COMBI compost screening machine is optimized and designed to produce precise screen sizes for compost and other organic materials.
