EQUIPMENT SPOTLIGHT | SEPTEMBER 2025 Pulverizers

When recycling WEEE (waste from electrical and electronic equipment), optimal size reduction equipment is vital in achieving high purity and recovery of materials. Examples of WEEE may involve household appliances to computer equipment. Proper recycling and disposal of WEEE is crucial, due to the potential hazards of the materials they may contain and the environmental impact of improper handling. Most of the materials involved are comingled with other types of commodities that are often challenging to separate and recycle – to then be converted for use in new products. Through pulverizing, shredding, crushing or other processes (magnetic technology, dry or wet density separation technologies), liberation and sorting of materials into individual constituents can be achieved. Regardless of the technology used for the proper recovery of these materials, the generation of global e-waste continues to grow and is estimated to reach 74.7 million metric tons by 2030.

The Eldan Heavy Duty Granulator (HDG) is modified for recycling tough material, including electrical waste such as ASCR cables, low-grade cables with some impurities – as well as nonferrous metals, refrigerators, industrial waste and more. The product’s new knife system with integrated rotary knives/knife holders with a rotor, provides a solid foundation for the resistance required when processing heavy objects. The knives are straight, can be used on all four sides and grind materials easily. Friction clutches protect the machine from material overload and the belt drive involved ensures a simple transmission. The HDG also processes RDF well and can produce 20 mm material size. The HDG also performs well as a pre-chopper for these materials and other Cu or Al cables and can include various screen hole sizes down to 12mm and upwards, according to customer requirements.

A summary of HDG features includes: adjustable knife clearance, which optimizes the cutting function; product knives that can be reground multiple times on a “flat-bed” grinder, ensuring long life and low operation costs; the HDG design allows for the quick and easy change of knives and screens; the rotor is manufactured and designed for minimum wear with hard-face welding; screens provide different hole sizes for flexible production; five pieces of screens per set are included and interchangeable, depending on wear and exchangeable wear parts “provide operators with a virtually indestructible machine,” remarked Carsten Nielsen, product manager.

Lindemann ZM metal crushers are efficient, low-maintenance metal processing products for pre- and postshredding. Most often used in scrap yards, the equipment is used in ferrous and nonferrous recycling applications, including the processing of electronic scrap.

“Our products offer impressive performance, with good material breakup at favorable specific energy consumption and maximum availability. At the same time, the ZM shredders are easy to maintain and resistant to unshreddables,” said Gunard Polite, general manager sales, North America. Product features include: top loader design; optimum double-grid/anvil combination – a design that helps to reduce power consumption and increases throughput at the same time; hydraulic removal of coarse pieces – so unshreddable parts are removed during the shredding process without interruption and without crossing the material flow; effective wear and maintenance prevention – these related costs are kept to an absolute minimum by the tiltable housing, the special wear protection of house parts subject to heavy loads, the design and arrangement of wear protection elements and the nature and arrangement of their fixtures; rotor lifting device – this facilitates access to the base section of the machine, as the rotor can be lifted together with the center part of the housing; optional hydraulic pin puller, which facilitates and speeds up the exchange of the hammers and hammer pins.

The machine is available in two sizes with 250 to 370 kW drive power, the capped rotor size (impact circle diameter) is 1,500 mm and offers individual speed control with throughput/hour up to 25t.

Schutte Hammermill’s DataKiller Pro and RAS models are designed to meet the evolving demands of the electronics recycling industry. The DataKiller Pro combines a dual-shaft shredder and dual-stage hammer mill into one, compact unit, destroying data and reducing materials to sub-2mm particles in a single pass. The machine processes up to one hard drive per minute and up to twelve solid-state drives per minute, handling various electronic media without reconfiguration.

The RAS Series Dual Stage Hammer Mill features two stacked gravity discharge hammer mills, ideal for reducing bulky e-waste and achieving consistent fine grind in a single pass. The dual-rotor design suspends material between grinding chambers, maximizing reduction efficiency and throughput.

“As electronic devices continue to evolve rapidly, so does the volume of outdated and discarded equipment. For recyclers, the efficient processing of e-waste, while ensuring data security and material recovery, presents both a challenge and an opportunity. With industry demand for secure, high-throughput, and fine particle size reduction on the rise, equipment that is purpose-built for this situation is the ideal solution. Our RAS and DataKiller Pro models have become go-to solutions for recyclers seeking durability, flexibility, and consistent results in today’s fast-paced electronics recycling environment.” Bill Castine, general manager, stated.

Schutte Hammermill has been a leading manufacturer of size reduction equipment since 1928. Known for rugged, reliable, and precisely engineered machines, the company serves a wide range of markets including e-waste recycling, data destruction, wood processing, and industrial recycling. As a part of the Bengal Machine family of brands, Schutte Hammermill continues to innovate and deliver equipment tailored to real-world processing challenges.
