Dry screening plant proves its worth in the field

The R2500 is a static primary screening unit capable of processing more than 500 tonnes per hour in quarrying, recycling and mining operations.

It is an expansion to the CDE portfolio of products and broadens the range of CDE?s services. The R2500 seamlessly integrates into an existing or new washing system and ensures an increase in efficiency. It is electric, resulting in a substantial saving in fuel costs and a quieter, green-friendly operation.

The R2500 has been designed at CDE?s new innovation centre, at the company?s headquarters in Northern Ireland.

In providing solutions to the world?s leading global construction companies, CDE is constantly researching and developing new products, and a particular focus in 2013 was the development of equipment solutions capable of processing more than 500 tph. This included the M4500 wash plant, which is capable of processing 450 tph and was launched to the international market at ConExpo-Con/Agg in March 2014.

CDE sales director Enda Ivanoff said the company recognised an opportunity to increase the processing capability of its washing solutions with the R2500 for customers that require higher outputs.

The R2500 can be introduced to quarrying, recycling and mining operations where a range of difficult materials are being processed, including crushed rock, topsoil, scalpings, iron ore and construction and demolition waste.

Features of the R2500 include a patent-pending laminate side wall design on the ProGrade P2-75/R screen that has zero welds.

The welds result in a stronger, lighter screen that requires less power and is galvanised as standard. The lattice design screen has a reduced mass and ensures more energy is transferred to the material, guaranteeing superior screening performance.

The ProGrade P2-75/R screen has finite element analysis (FEA) verification, and is an integral part of the CDE range, featured on the R2500, M2500 and M4500. All FEA results are verified with on-site physical testing procedures. Physical tests have also been carried out on the R2500 within the dedicated ProGrade screen testing facility at CDE.

Creagh Concrete is the largest land-based sand and gravel producer in Northern Ireland.

The sand and aggregates Creagh produces at various locations is used in the production of a range of pre-cast products as well as ready mix concrete.

The Creagh reserve is characterised by heavily clay-bound material with about 30 per cent waste. A modular CDE plant was installed in 2012 and consisted of three modular components from the CDE core product range ? an AquaCycle A1500, an AggMax portable log washer and an EvoWash sand washing plant.

In early 2014, Creagh Concrete introduced the R2500 to its production as a primary screening unit directly feeding the CDE AggMax.

The R2500 seamlessly integrated with the other CDE modular plant items. Its main function is to protect the CDE plant by screening off large stones and boulders and stockpiling this material ready for crushing.

Creagh Concrete has already praised the design and functionality of the R2500. ?The combination of processes on one chassis really sets this machine apart from others on the market, as it can handle extremely rough material, like ours, with ease,? Creagh quarry manager Conor McGlone said.

?With a 20 tonne hopper capacity we are confident the R2500 can more than meet our processing requirements. Overall, the machine is fit for purpose, quiet and visually appealing.

?Our raw material is among the worst that I?ve seen and at the outset, in 2012, all options were on the table, including ceasing production at our Draperstown quarry and looking for reserves at a new site.

?The CDE plant has allowed us to continue working at the existing site and the introduction of the R2500 has highlighted further efficiency improvements we can make to the washing plant.?

Effective from May 2014, the R2500 became operational in the Stuttgart area in southwest Germany.

A new project, backed by the Eco-Innovation Fund from the European Union, is operating with the aim of enhancing infrastructure for the recycling of construction, demolition and excavation waste in Europe.

The project is a partnership between CDE Global and the Eco-Innovation Fund and will see the introduction of a new construction, demolition and environmental (CD&E) waste recycling system, which includes the R2500. It will deliver on a number of key objectives, including reduced plant footprint, enhanced mobility and an increased return on investment from CD&E waste recycling operations.
