CDE Demonstration Events Feature Logwasher, Thickener

Materials washing manufacturer CDE Global hosted a demonstration event in Cologne, Germany, in April, and will host another in Stuttgart in June. A future event will take place in the United States.81 CDE1 400

The Cologne event was hosted at a site operated by Joseph Bohnen GmbH where CDE equipment is being used to process sand and gravel. The plant includes the M2500 mobile washing plant, AggMax portable logwasher and an AquaCycle thickener which facilitates the recycling of 90 percent of the water used in the washing plant.

Introduction of the AquaCycle thickener was critical to the success of the plant for Joseph Bohnen GmbH as a result of difficulty accessing the volumes of water required to feed the washing plant. “Water is not readily available at the quarry and we also required a plant that would require minimum space on site,” said Matthias Haus, company director at Joseph Bohnen GmbH.

The plant was designed with a focus on resource and energy efficiency and as a result of the solution offered by CDE the company was able to secure funding from the BMU Environmental Innovation Program. This was made possible due to the capability for the plant to recycle 90 percent of wash water by introducing the AquaCycle thickener and also as a result of the reduced CO2 omissions from the efficient deployment of clean, electric power and small plant footprint.

“The modular nature of our equipment is proving very popular,” said CDE Business Development Manager Paul Larkin. “It is increasingly the case that operators are looking for equipment with a small overall footprint, that is quick to set up and can be operated efficiently in relation to both the power required and the water volumes needed. Our equipment design also highlights that mobile and modular does not involve compromising on access or safety for site personnel. Our design simply integrates a number of processes onto a single machine ensuring the most efficient transfer of material from one processing phase to another and maximising product yield for our customers.”

81 CDE2 400The Stuttgart event in June will take place at a site operated by Feess Erdbau in Kircheim Recycling Park where a CDE plant for the recycling of construction, demolition and excavation waste has been operating for the last 18 months.

This will be the second demonstration event hosted at the Feess Erdbau site – the first taking place in September 2014. This was a project that was supported by the EU Eco Innovation Fund as a result of the product developments it launched including enhanced mobility, reduced plant footprint, a reduction in CO2 emissions from the plant and the development of new sludge management technology.

“We expect visitors to the June event to come from all over the world,” said CDE Regional Manager for Europe and Russia Eoin Heron. “We had visitors from throughout Europe as well as Australia, the U.S., Middle East, Africa and Brazil in September, and we’ve already taken registrations for the June event that indicate it will have the same international appeal.”

The plant at Feess Erdbau includes M2500 mobile washing plant, AggMax portable logwasher, AquaCell thickener and a decanter centrifuge for sludge management. “The application of the M2500 and AggMax on these contrasting applications is evidence of the versatility of the machine,” said Heron. “As well as sand and gravel, crushed rock and construction and demolition waste we have also developed specific machines for silica sands, iron ore and other mineral ores.”

According to Heron the two events in Germany will be followed by additional demonstration events in Europe as well as Brazil, Australia, India and the United States.
