Recycling
A tailored solution
Marc Sopransi, Business Development Manager at CDE, explains how the commissioned plant is the result of a detailed site audit and clear understanding of aims and objectives of the Pélichet operation.
“The technical approach around this project was based on the resolution of four objectives. The main one being to maximize the incoming material, to be able to process more complicated materials than Jérôme was able to treat before. The second, improving the quality, so treating more dirty materials – ultimately to bring them to a better quality. The third, on the environmental side, to be self-sufficient in terms of consumption of water. And the fourth, to be able to implement according to the constraints of the site.
Using CDE’s co-creation approach, a solution that married CDE’s technical expertise and Pélichet’s commercial and environmental objectives was developed. CDE's client approach is unique,” Marc said. “Jérôme found it interesting to be able to develop this solution live with the designer.”
Jérôme added, “CDE offered me a complete installation – turnkey – with a very strong analysis at the beginning to understand my needs.”
An innovator in cyclone technology, CDE has designed and delivered almost 2,000 projects globally since 1992 to increase the efficiency of materials washing operations. The solution is “based on the latest patented innovations from CDE,” explained Marc Sopransi.
“Each customer has their own unique challenges, be they geographic – or site limitations – or related to feed material.
Every wet processing solution we commission is tailored to the customer. Of the near 2,000 projects CDE has commissioned worldwide, each plant would feature something unique to respond to the particular challenges of that site or project, and Pélichet is no different.”
In response, CDE presented the blueprint of a bespoke wet processing plant, including the R2500 primary scalping screen designed to handle heavy clay-bound gravel, rock and mineral ores and construction, demolition and excavation waste. The R2500 ensures the efficient delivery of difficult material to the wet processing plant.
It feeds the AggMax 251 modular scrubbing and classification system, engineered to maximise product yield from clay-bound feedstock.
CDE’s flagship EvoWash technology – a compact, modular sand washing system – integrates a high frequency dewatering screen, sump and hydrocyclones to provide unrivalled control of silt cut points and eliminate the loss of quality fines producing a range of high-quality sands.
Addressing the company’s desire to completely self-sufficient in terms of water supply, the plant design incorporates a full water management system which recovers and recirculates up to 95% of process water.
The system includes an AquaCycle thickener which uses a flocculant to separate clean water from the solid particles. The solid particles form a sludge which is dried further in the Filter Press, recovering more water for recirculation and creating a dry filter cake which can be used for pipe bedding and landfill capping.
