Combo encompasses five processes: feeding, sizing, sand washing, stockpiling and complete integrated water management.
Sean Kerr, chief operating officer at CDE, said the Combo is a technological response to the challenges faced by materials producers.
“Offering a turnkey solution that delivers unrivalled control of in-spec washed products from a wide range of feed materials, the Combo can be used in the construction, C&D waste recycling, industrial sands, mining and environmental sectors,” said Kerr.
According to CDE benefits include rapid onsite set-up, reduced start-up costs, the ability to process a wide range of feed materials (both natural sand and crushed rock), lower power consumption, a smaller footprint and easy accessibility for maintenance.
The Combo is pre-tested and pre-wired before dispatch and arrives on-site in a single unit ready to plug and play either as a standalone plant or as part of a larger turnkey solution. The plant is built for rapid assembly and set up and is designed to start processing material within days of arrival onsite.
It sits on its own chassis so operators can now easily relocate their plant across sites or to remote locations.Its smaller footprint is designed to make it makes suitable for tight quarries in urban settings.
With all essential processes being housed onto one chassis, the Combo system operates as one interconnected and pre-assembled unit which incorporates an integrated control panel with one single point of operation.
The wet processing system can produce up to two in-spec products from natural sand or crushed rock, enabling it to turn what is often considered a waste by-product into a product that adds value to the business.
In addition, the new technology allows customers almost total independence of water supply with up to 90% of process water recycled for immediate re-use. This is ideal for jurisdictions with limited resources or those with existing environmental or impending environmental legislation.
“Global demand for construction sand is more than 15 billion tonnes per year, said Kevin Vallely, CDE director of engineering. “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.
“Our sustainable technology producing washed and graded manufactured sand is helping supplement natural sand which is a finite resource and increasing in cost. By utilising normally low-value crusher fines for sand production we can extend the life of natural resources and add huge commercial value to our 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. Sand can be produced closer to where concrete is required, resulting in significant aggregates transport cost savings.
