Modern Quarrying Q3 2019

CDE used bauma 2019 to unveil its CDE Combo™, the world’s first all-in-one wet processing plant.

If the plant is running at below optimal utilisation where weightings and output are unbalanced against set targets or failing to maximise on production capacity, the plant will respond to address the issue itself in real time by, for example, adjusting feed rates. At the centre of Intelligent Plant is OptiMax technology, the latest addition to CDE CORE – an innovative range of technology solutions developed to give customers greater control of their plant. CORE uses automation and sensors to monitor and enhance productivity, minimise downtime, automate processes and lower operating costs while maximising profitability. Examining how an OptiMax Intelligent Plant would boost plant efficiency, a 5% increase in production on a 150 t/hour plant would produce 7,5 extra tonnes every hour. Over the course of one year, this would equate to 2 000 additional hours. Where 1 t of C&D material is worth ZAR 274 / £15 in total revenue (incoming gate fee and sell price), an Intelligent Plant would generate ZAR 4,112-million / £225 000 in extra revenue. New world of resource “At CDE we are unlocking a new world of resource and driving alternatives for sand production. Global demand for construction sand is more than 15-billion t per year. Sand accounts for 35% of concrete which is used in the building construction industry. Large parts of the world face increasing demand for infrastructure and civil projects in the face of diminishing natural resources,” says Kevin Vallelly, director of Engineering at CDE. Vallelly adds that CDE’s sustainable technology producing washed and graded manufactured sand is helping to supplement natural sand which is a finite resource and increasing in cost. By utilising normally low-value crusher fines for sand production, CDE can extend the life of natural resources and add huge commercial value to its customers’ enterprises. “The Combo requires a small supply of fresh water compared with traditional systems which typically consume 10-15 times more water, allowing its deployment in quarries and urban areas not previously known for sand production. In addition, sand can be produced closer to where concrete is required, resulting in significant cost savings in the transport of aggregates. The Combo is industry-leading technology designed to unlock a NewWorld of Resource essential to protect our environment and build the world of the future,” concludes Vallelly. l
