Complete Shredding Solutions –
From Infeed to High-Value Output
At Lindemann, we deliver more than just shredders — we provide fully integrated scrap processing plants designed to maximize recovery, purity, and environmental performance across the entire value chain.
Our systems combine robust pre-shredders with high-performance main shredders to ensure optimal material preparation and throughput.
Pre-Shredding & Shredding –
The Heart of the Process
-
Pre-shredders enable controlled size reduction, protect downstream equipment, and increase overall plant efficiency while reducing peak energy consumption and frequency of unshreddables and explosions -
Main shredders are engineered for maximum uptime, high throughput, and consistent particle size
-
Intelligent system integration ensures optimal material flow and reduced operational costs
Air Treatment & Environmental Compliance – Meeting the Highest Standards
Emission standards for fine dust, VOCs, PCBs, and dioxins are becoming increasingly stringent. Lindemann provides comprehensive air treatment solutions to help operators meet regulatory requirements, avoid penalties, and ensure sustainable operations.
Our systems are designed to minimise emissions of pollutants such as heavy metals, hydrocarbons, VOCs, PCBs, and dioxins, while also reducing dust levels and enabling the recovery of valuable fine metal particles.
Available technologies include:
-
Wet filters -
Dry filters
-
Ultrafilters
-
Activated carbon filters
These modular solutions can be tailored to specific plant configurations and local environmental regulations, ensuring compliance with the highest emission standards worldwide.
Ferrous Separation – Reliable Recovery
and High-Quality Output
After shredding, Lindemann applies a combination of density and mechanical separation technologies to efficiently process the shredder output and generate clearly defined material streams.
-
The process starts with density separation (air classification) to remove dust and low density materials from the shredder fraction, ensuring maximal downstream processing conditions
-
The remaining material is then conveyed across two-stage magnetic separation (magnetic drums) to efficiently separate ferrous metals (FE) from non-ferrous materials
-
Depending on the required product quality, the ferrous fraction can be further refined using a ballistic magnetic separator or polishing drum magnet, enabling the removal of copper-bearing composites (commonly referred to as “meatballs”) from the iron stream, resulting in low-copper shredded steel (#1 Shred)
-
The secondary ferrous product (#2 Shred) is subsequently subjected to a final quality control stage, which can include manual sorting or AI-supported robotic sorting systems to ensure the highest purity levels and consistent product specifications
Downstream Processing of
Light and Non-Ferrous Fractions
In parallel, the light fraction separated in the air classification stage is processed further:
-
The light material stream is guided through a cyclone system, generating the so-called SLF (Shredder Light Fraction)
-
SLF consists mainly of light materials such as plastics, foams, textiles, dust, and residual fines, but may still contain small metal particles requiring further recovery
This step produces two key output streams:
-
Zorba: a mixed non-ferrous metal fraction, primarily consisting of aluminum along with copper, brass, and other non-ferrous metals; a valuable commodity for further upgrading
-
Refined SLF: a largely metal-depleted light fraction, suitable for further treatment, energy recovery, or disposal depending on local requirements
Heavy Fraction Processing
and Advanced Metal Recovery
At the same time, the process generates a heavy fraction (SHF – Shredder Heavy Fraction) during magnetic separation
-
SHF consists of dense materials such as stainless steel, heavy non-ferrous metals, and complex composites
-
Through screening and eddy current separation, the SHF stream is further processed to recover additional Zorba fractions, maximizing non-ferrous metal recovery
-
In parallel, a heavy non-ferrous fraction is generated containing stainless steels, heavy metals, and complex composite materials, including components such as cables and electronic scrap (e.g. printed circuit boards).
-
Applying a secondary round of aspiration-based debulking on this fraction maximizes the recoveries of the remaining non-ferrous metals. This material stream is then treated using advanced sensor-based sorting technologies, enabling the concentration of a high-value product known as Zurik
-
Zurik is a mixed heavy non-ferrous fraction, typically composed of stainless steel, copper-bearing materials, and other complex metal composites. It may include insulated copper wires, electronic components, and mixed alloys, and is specifically suited for specialized downstream refining and recovery processes
