How Metal Recycler Koslow Is Optimizing Its Sensor Sorting Process
Iwan Kowlos GmbH & Co. KG, a medium-sized metal recycling company based in Landshut, is one of the most innovative metal recyclers in Germany. The company’s goal is to provide its customers with excellent sorting quality in a reliable and highly cost-effective manner. Since 2013, it has relied on SPALECK conveyor and separation technology for this purpose. In a recent retrofit project, the recycling specialist switched the material feed for its sorting lines to the ActiveFEED feed hopper. This offers him significant efficiency gains in plant operations:

Retrofitting the Material Feed System as a Lever for Improving Material Quality and Reducing Production Costs
IN ACTION
Since 2013, the recycling screen has replaced a drum screen. A clear advantage: significantly higher metal yield and virtually maintenance-free operation.
Koslow switched its sorting lines to ActiveFEED because of the economic benefits. The exchange was simple, and the benefits were immediate.

Koslow has over 80 years of experience in metal recycling. During this time, the company is constantly optimizing its processes. By replacing the previous material feeding system, we have now created a significant opportunity to improve sorting quality and reduce production costs per metric ton.
In the video, Michael Kannengießer talks about the benefits of his eight ActiveFEED units in metal recycling. For plant operators, these provide maximum transparency regarding plant operations and enable significantly greater efficiency and cost-effectiveness.

More Information
Koslow focuses on optimizing the entire metal recycling process. The SPALECK recycling screen sorts the material by particle size. The screen liners used require virtually no cleaning and prevent the carryover of long pieces and fine particles.
The newly installed ActiveFEEDs replace the old feeding system. What’s new is that, for the first time, the plant operator can feed the optimal amount of a given material into the sorting process at the push of a button. And all this without interruptions and with optimized layer height and belt occupancy for the best sorting quality.
ActiveFEEDs also provide operators with relevant KPIs in real time. This gives him a very clear picture of how his investments are performing in real time.

TRANSFERABILITY for Your Processing
Each of the eight ActiveFEED feed hoppers supplies a sorting machine, including eddy current separators, XRF sorters, X-ray sorters, and combination machines. This ensures that they are continuously, fully automatically, and without clogging fed the optimal amount of material. This makes it possible to
The material feed for the non-ferrous metal recycling plant in Wörth an der Isar has been fully converted to the ActiveFEED system. To this end, the old belt feeders were replaced with the intelligent feeding technology of the ActiveFEED feed hopper. The switch is technically straightforward and offers seamless integration into existing systems.
No matter what the input material is, ActiveFEED delivers the amount specified for the respective sorting process to the sorting machine.
From wheel loader operators to manual sorters: ActiveFEED enables safe and efficient work.
No blockages, no underfilling or overfilling of the sorting system, and no unintended interruptions in the material feed.
With its optimized material feed, ActiveFEED enables significant efficiency gains for the plant’s overall operation.

TRANSFERABILITY for Your Processing
The project shows that the quality of the treatment is largely determined by the upstream process steps. The combination of classification and controlled material feed can be applied to many applications:
BEST SCREENING. BEST SORTING. FOR YOUR METAL RECYCLING.

Here are some questions about the SPALECK Activefeed feed hopper. We’d be happy to help you find the right solution.
ActiveFEED enables a very quick return on investment, as the optimized material feed to the sorting equipment makes it very easy to process more material in less time and achieve higher sorting quality. As a rule, the payback period is therefore well under one year.
ActiveFEED increases transparency and gives plant operators greater control over their recycling processes by allowing them to manage their material feed—and thus the throughput of their recycling plant—both in advance and in real time. For example, he has real-time information about
With ActiveFEED, many recycling companies can eliminate entire shifts and significantly reduce their workforce. This is made possible by the optimized, jam-free material feed provided by ActiveFEED. This eliminates the need for extra work caused by blockages, unintended idling of the sorting equipment, and inefficient monitoring of hopper fill levels by the wheel loader operator. All in all, this saves a lot of work time.
