Although highly suited to primary aggregate production in quarries and sand and gravel plants, Screencore’s mobile and modern range of mobile solutions has found a real niche in processing materials from construction operations. Possessing exceptional productivity while being fuel efficient, the crushers, screens, and stockpilers are now at work throughout the world processing a variety of materials, turning what was once considered to be waste into a valuable resource.
Companies working in the demolition and recycling industries have quickly seen how Screencore material processing and handling equipment can aid their business operations. Playing a major part in the success of Screencore has been the company’s extensive international distributor network. The relationship forged has led directly to several compact Screencore tracked jaw crushers, Trident scalper-screens, Orbiter trommels and radial stockpilers being used to recycle construction and demolition materials. A bespoke selection of stationary recycling plants can now be added to this. These solutions are designed to benefit users, helping them turn waste into high-quality aggregates and other valuable products.
The adoption of Screencore equipment by distributors in such countries as the US, France, the UK, Australia and South Africa (often alongside existing product portfolios) directly points to the versatility and processing efficiency of the Screencore range. “The Screencore product range was developed to meet the needs of the modern contractor and materials handling operation. We have set out to build the highest standards of equipment that helps people in the field be more profitable, efficient and effective in what they do. We have also incorporated environmental efficiency into our processes to minimise customers’ carbon footprint. All this has meant that working with our distributors has seen Screencore equipment adopted on numerous projects, turning construction waste into reusable and/or resaleable products,” explains Screencore director Ciarán Ryan.
A typical application – in this case in the US – sees, in the first instance, a Screencore XJ Dual-Power Crusher being fed the demolished or excavated material, usually by an excavator or loading shovel. The Screencore XJ itself is a dual-power 1000mm x 650mm (40″ x 27″) jaw crusher designed with a compact footprint. It has proved to be ideally suited to the modern demands of a recycling contractor, rental fleet or inner-city demolition/recycling site. It weighs in at just 30,000kg (65,000 lbs), so it can be easily relocated without permits. It is designed to be environmentally and acoustically friendly while delivering impressive throughput even on hard rock applications or concrete with rebar.
Following crushing to -100mm (4″), the material is then fed into a 17,000kg (37,500lb) Trident 124 scalper/screener to produce 0/25mm,25/60mm and +60mm (1″, 2.36″ and +2.36″) products. In addition, any ferrous metals, such as rebar or wire, are easily removed for resale/recycling by the overband magnet on the XJ crusher’s discharge conveyor before being fed into the screen. In many applications, the 0/25mm material is generally used for pipe bedding; 25-60mm directly as road subbase or as feed material for secondary crushing for concrete production, whilst the +60mm is used as drainage stone. The combined set-up time for this crushing and screening combination is less than 30 minutes.
Due to the equipment’s easily transportable and modern nature, contractors and rental fleets have found that the Screencore crusher and screen combination can be readily transported to where the material is. This means that the material can be processed where it originated, and generally where it is needed, resulting in no unnecessary emissions, material handling or transport costs. In addition, the local environment is not subject to unnecessary traffic disturbances, and the contract’s overall carbon footprint is dramatically reduced. “Quick set-up times, easily adjusted closed side settings, fuel efficiency (dual-power) and ease of transport are just some of the reasons contractors and recyclers have adopted Screencore equipment,” explains Ryan.
For some operations, however, mobility is not essential. This has led Screencore to use its expertise to develop a range of bespoke stationery solutions based around its Orbiter trommel range, which works alongside Screencore stockpilers and scalpers.
Ryan continues: “Screencore provides a variety of customised stationery solutions tailored to suit individual applications. Our dedicated in-house design team collaborates with our distributors and customers to develop an efficient and long-lasting material handling system. Leveraging our electrical power expertise, we ensure that any system satisfies requirements.
“Screencore will custom-design conveyors, stockpilers and feeders to meet application requirements. Our designs are renowned for their quality and ease of assembly, arriving in neatly packed containers and specified to over-deliver on throughput expectations. We also supply a range of air separation systems for stationary and mobile plants. Engineered for plastic or ‘lights’ contamination removal from C&D, compost and mulch, the Revac and AirKnife units are available in diesel or electric power to suit customer requirements.”
Screencore’s stationary and mobile equipment have power solutions for various customer requirements. Stationary and increasingly mobile plants are electrically powered, which makes efficient and cost-effective use of main electricity to provide a low-cost and low-emission solution. “Screencore has gained much experience using electric power from various sources. Main electricity has proved to be an ideal power source, delivering a cost-effective and environmentally efficient solution. Through this power source, or the dual-power solution, precision processing of materials is accomplished without producing the emissions that would be of concern, and at the same time, at a low cost,” concludes Ryan.
