Conveying & Separation Technology
for
Recycling

There is hardly any recycling material for which a screening machine cannot be used. The materials include heavy and light materials, large to very small Particle sizes, moist and wet materials, as well as dusty or dry screened materials.

SPALECK screening machines do a great job in the recycling sector, the chemical and food industries as well as in the stone and earth sector.

Here we are screening and conveying, among other things:

• Municipal solid waste
• Commercial waste
• Construction and demolition waste
• Plastic waste
• Organic
• Earth
• Waste wood
• Wood chips
• Metals
• Slag
• Shredder light fractions
• Shredder heavy fractions
• ASR material
• Used tires
• Electronic waste
• Batteries
• Biomass
• Fertilizer
• Compost

and hundreds more materials.

A screening machine is used to separate and classify the material to be screened according to Particle size. The aim is to use Screening technology to divide the feed material of different sizes into size classes. The screening machine is used to separate the screened material according to size. The screening process is also known as classification. During the screening process, the material is cleanly and reliably separated into the desired Screen fractions.

Screening machines are also used for dewatering or Control screening. Typical applications are therefore Classifying, Controlling and Protecting, Separating, Dewatering and Separating Clumps.

In our videos you will find numerous explanatory and application videos of screening machines.

Screening quality is very important in recycling because it lays the foundation for good sorting quality. Screening machines are therefore indispensable for the recycling process of most recyclable materials. The more accurate the Screening process is, the better the overall recycling result will be. This is because optimum screening quality enables downstream recycling machines such as magnetic sorters, eddy current sorters, X-ray sorters, NIR sorters or air separators to process the individual fractions in the best possible way. In the circular economy, screens therefore play an important role in the recovery of recyclable materials and raw materials.

Screening by particle size is essential for processing and recycling.

This is because the downstream sorting devices (e.g. eddy current separators, air classifiers, sensor sorting devices, X-ray sorters (XRT / XRF), NIR sorting devices, LIBS technology) can only achieve optimum economic results with very clean fractions.

Depending on the type of screening machine, these are used for screening and classification into the following particle sizes and applications:

– Coarse screening & pre-separation
– Classification screening
– Fine screening
– Dewatering
– Control screening
– GMP-compliant screening

Depending on the type of screening machine, screening machines are available in very different sizes:

While GMP-compliant screening machines in food production are generally smaller, we produce our screening machines for recycling as standard in sizes of up to 2 x 10 m or 3 x 10 m.

There are also Single-deck, Double-deck and also Three-deck screening machines.

Screening machines are available as mobile screening plants on the one hand and as stationary screening machines on the other.

The following types of screening machines are available, which you can find in the overview:

Vibrating screens
– Vibrating conveyors
– Vibrating screens
– Elliptical screens
– Linear vibrating screens
– Banana screens
– Eccentric screens
– Setting machines (often for sand and gravel processing)

Flip-flow screens
– Single-deck Flip-flow screen
– Double-deck Flip-flow screen

Other
– Drum screeners
– Flat screening machines
– Laboratory screening machines
– Centrifugal screening machines
– Tumbler screening machines
– Drainage screens
– Wet screening machines

Yes, SPALECK produces screening machines with three screening decks.

Three-deck screening machines from SPALECK are mainly used in the food and process industries, where several fractions are required simultaneously.

In the classic recycling sector, SPALECK mainly relies on single- and double-deck screening machines, with which – depending on the machine type – up to five fractions can be produced.

Yes, SPALECK also manufactures screening machines in the color of your choice. In addition to the technical design, the machine can also be visually adapted to your system or corporate design.

Yes, SPALECK specifically helps recycling companies to improve their Screening processes.
The SPALECK TestCenter is often used for this purpose:

• material is tested on an industrial scale
• different screen configurations can be compared
• the optimal solution is determined

The aim is to achieve higher product quality, better separation and more stable processes.

Find out more in the TestCenter section.

The special feature of SPALECK screening machines is that they are individually designed for your process and your material.

Each machine is matched to:

• Recycled material
• Desired fractions
• System environment

The ModularDESIGN+ concept also offers:

• High flexibility
• Simple customizability
• Easy to maintain design

SPALECK ensures consistently high quality thanks to its high level of in-house vertical integration in metal processing and Machining.

Yes, SPALECK supplies screening machines and conveyor systems worldwide.

Yes, SPALECK can help to improve existing screening processes – even with third-party machines.

Typical problems are

• Poor screen quality
• Carryover of long parts
• High cleaning and maintenance costs

SPALECK analyzes your material and your process and develops an optimized Screening solution based on this.

Thanks to the ModularDESIGN+ concept and special screen linings:

• More precise Screening sizes
• Reduced maintenance effort
• Improved material quality achieved

You can find practical examples in the References section.

A test day at the SPALECK TestCenter is free of charge for you. You only bear the transportation costs for your material.

Test execution, analysis and technical evaluation are included and help you to optimize the planning of your system and the overall process.

More information in the TestCenter section.

The optimum configuration of a SPALECK screening machine is determined together with you.

Among other things, the following are taken into account:

• Material properties
• Desired fractions
• Throughput and process target

To validate the design, SPALECK uses the SPALECK TestCenter, where your material is tested under real conditions.

The delivery time of a SPALECK screening machine is agreed individually with the customer.

It is based on:

• Project planning
• System integration
• Customer-specific requirements

SPALECK reacts flexibly to changes, e.g. with:

• anticipated requirements
• Construction delays
• Approval processes

We will be happy to provide you with details on project management in person via WhatsApp or in a short meeting.
