Page 46 of 91 ROCKproducts • June 2019 • 45 EQUIPMENT & TECHNOLOGY SCREENING & SIZING CDE launched the Combo all-in-one wet processing plant. The Combo encompasses five processes – feeding, sizing, sand washing, stockpiling and complete integrated water management, which is a first for the industry and an import- ant innovation to address a challenge faced by all customers of wet processing systems, according to the company. Sean Kerr, chief operating officer, CDE said, "The Combo is no ordinary machine but rather a technological response to the challenges faced by materials producers. It has been designed with a focus on transferring greater reliability and efficiency benefits to customers. Offering a turnkey solution that delivers unrivaled 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." In brief, the Combo creates enhanced reliability and efficiency offering rapid onsite set-up, reduced start-up costs, the abil- ity to process a wide range of feed materials (both natural sand and crushed rock), lower power consumption, a smaller footprint and unrivaled accessibility for maintenance. Pre-tested and pre-wired before dispatch, the Combo 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 can start processing material within days of arrival onsite. Also, as it sits on its own chassis, the Combo requires minimal civils and pipework so operators can now easily relocate their plant across sites or to remote locations. Its smaller footprint also makes it ideal for tight quarries in urban settings. With all essential processes being housed onto one chas- sis, the Combo system operates as one interconnected and pre-assembled unit, which incorporates an integrated control panel with one single point of operation. Significantly, the Combo wet processing system can produce up to two in-spec products from natural sand or crushed rock turning 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 pro- cess water recycled for immediate reuse in the system. This is ideal for jurisdictions with limited resources or those with existing environmental or impending environmental legislation. A customer-focused solution, the Combo has been designed for single-operator use and unrivalled ease-of-access for routine maintenance with its patented swivel access to the pump leading to maximum production and prolonged life. Lower power consumption compared to existing technol- ogy available on the market means customers can process a higher volume of materials with reduced operating costs generating exceptional return on investment. Kevin Vallelly, director of engineering at CDE, said, "At CDE we are unlocking a new world of resource and driving alter- natives for sand production. Global demand for construction sand is more than 15 billion tons 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. "Our sustainable technology producing washed and graded manufactured sand is helping supplement natural sand, which is a finite resource and increasing in cost. By utiliz- ing 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 tradi- tional systems, which typically consume 10 to 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 result- ing in significant cost savings in the transport of aggregates," Vallelly concluded.
