Terex Washing Systems (TWS) at Hillhead 2018 will unveil its latest modular concept that it says is set to be an innovative game-changer in the mining and construction/demolition recycling markets. “Pit and quarry operators can look forward to more intelligent ways to wash sand, gravel, aggregates, and C&D waste thanks to this new high performance solution that brings together rinsing, screening, scrubbing and sand washing capabilities on a single plant.”
TWS says this latest offering has been months in design and development, engineered specifically with large-scale production processing in mind. It has primarily been designed for the efficient processing of C&D waste but equally suited to virgin mined material applications. The plant will have the capability of producing up to six grades of saleable product, and has been designed with an uncompromising approach towards robustness and reliability.
Hillhead 2018 will also be the stage for the global premiere of TWS’ new water management offering, Terex AquaClear™. The range includes clarifying tanks, flocculant dosing systems, filter presses and all associated equipment enabling TWS to offer an end-to-end solution for washing and water management. There was a small demo of the technologies at CONEXPO-CON/AGG in 2017 but this is the first global showcase of the full scale equipment.
TWS has a dedicated technical team to support Terex AquaClear™, consisting of a product manager, engineers and applications specialists, together with a new, cutting-edge laboratory specifically designed for material testing and sample pressing. This ensures optimum equipment selection and specification for customers. Water Management Solutions are typically comprised of three main components; a floc dosing plant and thickener tank can be used to recycle up to 80% of the water used in the washing process. This basic method still involves the use of ponds but on a smaller scale as the sludge sent to the ponds is of a much higher specific gravity (1.5 SG). The next stage is to incorporate a filter press which hydrates this thickened sludge even further typically down to 25% moisture. The filter press eliminates the need for ponds as the sludge is hydrated to a material/cake which can be handled by a loading shovel. This cake can be used as a lining or capping material.
