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.
