The Expanding World of Crushing and Screening Equipment

Published: 31/5, 2021

In the prolific world of mobile crushing and screening, many new machines are being rolled out on the market and being put to work in exciting projects all around the globe – from Germany and Cyprus, all the way to Burkina Faso.


Waste management company uses Rotorshredder from BHS-Sonthofen

A challenge for recycling plants is contamination with other materials. A German waste management company turned to BHS-Sonthofen for a new recycling solution for the 30,000t of non-ferrous metals they recycle annually. They opted for the Rotorshredder, which shreds the feed material and breaks up composites. The Rotorshredder type RS 2018 was fitted with reinforcements for aluminum processing, including a hardened housing, double-walled base and new suspension system. The Rotorshredder uses selective shredding. Impact forces deform aluminum, causing impurities to break down. Composites are then separated from the feed material. After classification takes place, the high-purity aluminum is ready for sale.


Arjes shredders in use in Israel

Arjes shredders have been used in a variety of applications in Israel. Recycling company Gal Michsur uses the Impaktor 250 Evo to process materials. Shredded waste wood is mainly used as a substitute fuel in incineration plants and is obtained by an external company for fuel production. Prepared green waste is used for processing in composting plants. All metal contaminants are removed with the over-band magnet and the biomaterial is then screened. The generated commercial waste is shredded to reduce its volume to save transportation costs and landfilling, which are based on the material’s weight and volume, providing double the benefit to customers.

Another example is Carmel Natural Products Ltd., which shreds composted material and green waste on site with the Arjex Titan 950. The material is screened and processed with a high-speed machine to a grain size of less than .8 in (20mm). The Titan 950 also helps separate stones and metal that goes unnoticed during pre-sorting.

The Titan 950 also figures prominently at a large-scale waste collection point in southern Israel, where a large part of the waste is dumped and buried. Using the Titan 950, the volume of household and commercial waste is reduced so that more layers of waste can be deposited, which means more money for the system operator, according to Arjes. The twin shaft can be installed and removed quickly thanks to the quick-change system.


Haas – processing waste wood into biomass fuel

German waste disposal company BWE Balthasar GmbH was looking for a solution to process approximately 40,000t of waste wood annually into fuel for a biomass power plant. In a single-stage shredding process, wood chips of 3.1-4.7 in (80-120mm) with a minimum percentage of fines are to be produced. Haas supplied Tyron pre-shredder and the Alva star screen with oversize recirculation. The Tyron features a twin-shaft system that is suitable for hard wood such as railway sleepers with solid iron plates, as well as a neodym cross-belt magnet. The extra-fine tool configuration (7/6-4) provides BWE with excellent wood chip and high throughput, according to Haas. The Alva star screen separates out oversize material, which is returned to the shredder by the integrated recirculation conveyor. The integrated screw conveyor collects and discharges the usable fraction.


Lindner’s Polaris 2800 fuels one of Europe’s largest cement plants

Enerco – Energy Recovery commissioned a Lindner shredder from the Polaris series to shred high-calorific refuse derived fuels in Cyprus. Vassiliko operates one of the largest cement plants in Europe. To ensure the amount of energy needed to produce approximately 6,000t of clinker per day, they rely on Enerco’s resource-saving alternative fuels. The shredder produces onsite fuel in 2-in (50mm) particles out of end-of-life tires, mixed and bulky waste, and waste wood.

Another novelty from Lindner is their patented SF synchronous fine cutting system. The angle between knives is changed so that they act like scissors, applying force to a smaller area. This, according to Lindner, increases the tools’ impact while maintaining energy consumption. Also, the cutting edges of the shaft are not aligned in parallel. The shafts act like two Archimedean screws rotating in opposite directions. This intake increases throughput and mixes the final fraction for a homogenous output.


New mobile screen, crusher and e-Power range from Metso Outotec

Second Rockster crusher at Tropic Mining & Quarry in Burkina Faso

Tropic Mining & Quarry SASU (TMQ), based in Burkina Faso, has been using a Rockster R900 impact crusher since 2008. To increase limestone processing, a R1100S closed circuit impactor has been added to their fleet. The impactors are used to crush dolomite limestone, which is used for production of cement. The plan is to produce 600,000t of final material per year. TMQ’s R1100S also has a screening system, which consists of a screen box and return belt, to produce perfectly defined final product with an excellent quality.


Diesel-free with RM 120X hybrid

Israeli recycling and waste recovery firm Taha Zahir invested in a Rubblemaster RM 120Go! in 2018. Located in an enclosed hall, which makes low emissions essential, the crusher has been crushing C&D waste to produce road substructure aggregate. Taha Zahir has now added a second low-emission crusher—Rubblemaster’s RM 120X hybrid, which can be diesel-electric and purely electric powered. The feed material with an edge length of up to 800mm is processed electrically to produce cuboid final aggregate of less than 1.26 in (32mm). Taha Zahir also ordered a dust suppression system and installed a wind sifter on both crushers. Every day, approximately 1,000t of C&D waste, mixed with plastic, wood and textiles, are delivered to Kafr Qasim. The RM Go! principle has been developed for Rubblemaster’s new Next machines. With machine communication lights, the user can see the system’s current status. The RM 120X keeps the operator outside the danger zone during crushing. Information on the crushing process is displayed in the RM Go! Smart App.


Powerscreen reveals concept battery-powered screener

Powerscreen’s electrification strategy includes a new concept for crushing and screening – the Eco-Warrior battery-powered screener – designed to combine the company’s famed screening action with a simple, quiet engine with no after-treatment requirements. The required engine size has been cut in half compared with the diesel hydraulic unit, and the battery pack can mean emission-free running or give a power boost.

As part of Powerscreen’s decarbonization challenge, the company has broadened its product range to reduce environmental impact by making its crushing and screening equipment more fuel efficient, using direct drive systems for its crushing range and improving engine capabilities and drive-line design for its screening range.
