IFAT 2020: Performance that pays off – WEIMA offers various drive systems for waste shredders

At IFAT 2020 in Munich, the recycling specialist from Ilsfeld, Germany, will present its top-of-the-line PowerLine 3000 single shaft shredder complete with powerful hydraulic drive. In addition to this, WEIMA will also present a packaging and drainage press by PÜHLER for the first time. The well-established company from North Rhine-Westphalia was acquired in 2019 and now complements the recycling range of the WEIMA Group.

In the media and politics there is a great focus on sustainable use of resources as well as protection of the environment and the climate. IFAT is an opportunity to meet solution providers. After all: The modern waste management and recycling sector makes an important contribution to reducing greenhouse gases and reusing raw materials. Recycling keeps materials in the economic cycle for longer and means that they can be used more efficiently. Non-recyclable materials can also be used to generate energy, for example as a substitute fuel. Use of fossil fuels can therefore be minimized.

The cornerstone of any process is generally the size reduction of materials. That’s where industrial shredders come into play. At the world’s leading trade fair for scrap and raw material management, WEIMA will demonstrate the potential of single and multi-stage waste processing in practice with the PowerLine 3000.

 

WEIMA PowerLine 3000 shredder – for optimal processing of scrap as a substitute fuel

 

The PowerLine 3000, which is developed and manufactured in Germany, accepts all types of scrap including dirty materials from the post-consumer sector. The universally applicable industrial shredder has an 800 mm rotor diameter – with rotor lengths of 1,500, 2,000, 2,500 or 3,000 mm. A low loading edge means that the shredder can be easily filled with a gripper, wheel loader or conveyor belt. The upward extending swing arm and outward-opening, swiveling screen basket guarantee easy accessibility and safe maintenance at any time.

Depending on application, the flexible all-round machine can be equipped with a hydraulic or high-torque drive. It not only shreds commercial waste, industrial waste, bulky waste and household waste but also paper, plastic waste, wood scraps or carpet material. The PowerLine can be operated as a single or multi-stage system, and in multi-stage systems it is also suitable for the shredding of multiple material flows.

With the PreCut pre-shredders or the FineCut secondary shredders for smaller particle sizes, which are all available in rotor lengths from 1,500 to 3,000 mm, WEIMA covers the total range of waste processing services.

When you have a choice – the right drive for every application: Hydraulic, high-torque or electromechanical?

 

At IFAT, industry visitors can examine the PowerLine 3000 with a hydraulic drive from Hägglunds/Bosch Rexroth. This is particularly suitable for the manufacture of substitute fuel as it has no classic gearbox that is subject to wear during impacts. This means that it is quicker to react and less sensitive to impurities. Stopping, starting, and reversing is also possible at any time, even under full load and the most difficult conditions. Rotational speed and torque can be adjusted quickly, uniformly and steplessly without creating power peaks or requiring a frequency converter. The robust drive is very efficient, with extremely high torques at low connected loads.

To demonstrate the technical structure of the hydraulic drive, in cooperation with Hägglunds, WEIMA will present a manually controlled exhibit at the trade fair stand. This will allow visitors to learn more about the inner workings of the hydraulic unit.

Alternatively, the PowerLine series by WEIMA can also be operated with an innovative high-torque drive from Baumüller. The high-torque, multipole synchronous motor is also made in Germany and features a low sensitivity to foreign objects. The fact that there is no gearbox means that it withstands impacts and vibrations, giving it a longer lifecycle even when shredding challenging material flows.

There is also a clutch between the rotor shaft and the drive that protects the motor from damage and can stop the rotor immediately if foreign objects enter the cutting chamber. A frequency inverter allows exact adjustment of the torque and rotational speed to achieve an optimal result regarding throughput and the quality of shredded material.

In addition to the options described above, WEIMA also offers a conventional electromechanical drive, which is used, for example, in the FineCut series and the smaller WL or WLK machines. This reliable drive option is extremely low maintenance and low wear. A safety clutch protects the shredder from impurities and major damage.

WEIMA expands product range with PÜHLER presses

 

Swabian company on an expansion course: In addition to classic waste shredders, WEIMA is for the first time also presenting the recycling presses of subsidiary PÜHLER. PÜHLER develops recycling presses with a focus on drainage solutions and has been a subsidiary of the WEIMA Group since 2019. The EVP disposable packaging press on display is designed to open, drain, compress and press filled packaging. This allows filled TetraPaks, PET bottles, milk cartons, tins and other packaging to be reduced in volume and cost-effectively disposed of.

The press operates electro-hydraulically by means of different hydraulic cylinders. It can be filled manually, with a conveyor belt, tilting lifter or forklift turning device. Focus markets include the beverage, milk and brewery industries.
