JPE Aggregates to host demonstration days

JPE Aggregates are to host a series of demonstration day events at their site in Birmingham during February. The events are being organised following the installation of a new modular washing plant for construction and demolition waste material purchased from CDE Global in late 2010. The new plant includes the M2500 mobile washing plant, AggMax attrition system and AquaCycle thickener and has a capacity of 100 t/h with the capability to produce 70 t/h of a single washed sand. Representatives from CDE will also be present at the series of demonstration days and visitors will include construction and demolition waste processors from throughout the UK as well as a number of international visitors. Visitors will witness material being processed through the M2500 mobile washing plant which includes feeding, screening and sand washing on a compact chassis (Fig.). The sand washing element is achieved through the integrated EvoWash sand plant and an integrated 9m conveyor stockpiles this material.  
The aggregate material is delivered from the M2500 to an AggMax attrition system which includes a RotoMax RX80 Logwasher and double deck rinsing screen. Once the aggregate materials have been scrubbed they are then given a final rinse on the double deck screen and classified into the required aggregate sizes. This stage also allows for any -5 mm material to be recovered from the recycled aggregates and returned to the EvoWash to ensure maximum sand production. As is the case with many construction and demolition waste processors the issue of space available on site to accommodate the new washing plant was critical for JPE Aggregates. This has been addressed on the new plant with the inclusion of the AquaCycle thickener which allows for recycling of 90 % of the water used in the washing process.
 
Waste water from the plant containing the minus 63 µm material is delivered to the AquaCycle thickener where the dosing of polyelectrolyte forces the sludge to settle and the recycled water to be returned to the washing plant. The sludge is subsequently pumped from the thickener and the specification of the AquaCycle system greatly reduces the volume of waste material to be handled by JPE Aggregates while also minimising the use of fresh water. The demonstration events will be hosted during the week beginning 28th February and those interested in visiting the site can register for further information at www.cdeglobal.com/section/Eventscalendar
