Three fraction starscreen from Backers

Backers’ three fraction starscreen can, as the name suggests, screen in three fractions, or four with bar or grizzly screen. Coarse fractions fall off in the front, while medium and fine fractions fall to the rear and side. The model can screen cohesive oil with a high throughput, according to Backers, and after a short modification, it can be used as a screening and mixing machine and for the production of stabilised and liquid soil. For this, the fine screen must be replaced by a binder container. Both the sieving, and sieving and mixing machine, are designed to be used for areas of 700m² or more. The excavated soil is filled into the bunker and screened with the starscreen set at 60mm or finer. The soil falls loosened onto the lower belt, is weighed by the belt weigher, and conveyed to the blending station. Based on the belt weigher, the binder is fed from the binder container. It is mixed with the sieved and loosened soil by a hammer roller, and remaining agglomerates are broken up. Only as much compound as needed for the application is mixed into the soil, which is usually 1%-3%. Less can be carried out onsite, in accordance with BBodSchV. An output of up to 250t/h is possible when producing stabilised soil, according to Backers. The screening and mixing machine generates compressed air with which the binder is conveyed from a storage silo to the binder container. When the soil-compound mixture is transferred, water is pumped into the truck mixer. The liquid soil is produced in batches, documented with a delivery note, mixed in the truck mixer, and then poured.

Lindner’s ’Urraco 4000’ Series

Lindner’s mobile Urraco 4000DK twin shaft shredder and the ‘Zeta Star 4000DK’ screen were showcased at the RecyclingAktiv trade fair in Karlsruhe, Germany. Lindner’s mobile shredding solutions feature location independent flexibility and application options, being designed to deliver results ranging from efficient volume reduction to the production of specific, homogenous particle sizes. The Urraco 4000 diesel models are equipped with a Scania engine, while the models with Abb’s e-drive feature an independent power unit which makes it possible to move the mobile e-shredder without a power chord. Different cutting systems can be used for various particle sizes depending on the input material. Since Lindner’s patented cutting system shreds particles to a homogenous P100 size in the first production step, the system solution consisting of the Urraco 4000 and the Zeta Star 4000 is used to archive particle sizes in accordance with classification P63 F5 in line with EN ISO17225-1. For mobile shredding, the service packages, ‘Shaft Reconditioning – Mobile’, the ‘Urraco Filter Package’ and associated services are available. The Urraco Filter Package includes engine and hydraulics maintenance.

‘CBF’ and ‘CBF-L’ crusher buckets from CM

CM’s new CBF and CBF-L Series crusher buckets reduce the volume of inert material directly on site. They work synergistically with CM's ‘CBR’ series screening bucket which has been renovated with the basket lengthened by 80% depth wise and increased in diameter. As a result, the surface area of the basket is increased. The CBF-L Series is applicable to skid steer loaders, mini excavators, and backhoe loaders from 3t to 12t, while the CBF Series is applicable to excavators and wheel loaders from 10t to 45t. They have been redesigned structurally, mechanically and productively to meet the standards of the market. The CBF’s have a lower structure, resulting in greater penetration force in the loading phase and better weight balance, according to CM. The mouth is wider, which allows the crushing of blocks with larger dimensions than previously. The eccentric unit has been revised with increased with oversized bearings, and the transmission and flywheels have been increased in diameter and weight to provide more inertia while working. In the new CBR screening buckets, the basket consists of interchangeable bolted grids, and the basket grids are produced from 10mm to 150mm. None of the models requires a drainage line, and all models are birotary with speed adjustment in both directions.

New developments from Screencore

Screencore has broadened its scope to produce a range of dual power crushers and mobile pugmills. The company offers a range of mobile – and now stationary – crushing, screening, stockpiling and pugmill solutions. “While our product line has expanded to encompass the formidable 237 trommel and the 30t Trident 165 scalper, our fundamental concept remains consistent: simplicity of use,” says company director Ciarán Ryan. “This is evident in features like hassle free transport, swift setup time, intuitive control systems, and distinctive design elements such as full-sized bottom decks on scalpers or augers within the trommel hoppers.” The Screencore Boxer pugmill for precision mixing, blending and dosing has been added to the Screencore range.

Kleemann’s new ‘Mobibelt’ stackers aid worksite logistics

Kleemann’s Mobibelt mobile stackers are used to improve worksite logistics processes. They extend the action radius of crushing and screening plants, making large stockpiles. In modern crushing and screening, machine operators have a strong influence on product quality and daily output since they control the input with their excavators and wheel loaders. Users also coordinate the final products by means of building up stockpiles, intermediate storage areas and loading. With the new Mobibelt models MBT 20(i) and MBT 24(i), site logistics can be organised and adapted to the respective situation. Both stackers are equipped with a 1.25m³ feed hopper comprised of ‘Kleemann Resistant Steel’, which permits the feeding of material with an edge length of up to 200mm. An optional hopper extension up to 2.5m³ is provided with an additional impact bar that prevents direct impact of the feed material on the conveyor belt. Thanks to the hydraulically adjustable feed and discharge height, the stackers can be used behind screening and crushing plants with different discharge heights. The stackers feature the ‘Spective’ operating concept, which offers support with a central operating position, local operation and the option of troubleshooting help via ‘Spective Connect’.

New hybrid scalper and digital solution from Rubble Master

Rubble Master’s new H50X hybrid scalper saves up to 50% on fuel in a hybrid crushing and screening train, according to Rubble Master. As a hybrid variant, the screen can be operated electrically whilst also providing modularity. RM hybrid systems are said to achieve fuel savings of up to 25% in stand-alone operation and up to 50% when linked together and are flexible thanks to modularly combinable crushing and screening trains. When a diesel-direct crusher drives the new RM hybrid screen, the customer saves up to 33% on fuel, and in combination with an RM hybrid crusher which drives the RM hybrid screen, the savings potential reaches up to 50%, according to Rubble Master. If only one engine is running because the crusher is driving the screen, the customer only has to refuel and service one engine. In other news, Rubble Master has developed its digital solution ‘RM XSmart’, which is designed to provide operators with an overview of all machines, receive machine data and save time evaluating the situation. RM XSmart is available as a mobile app and web app.
