Terex Washing Systems (TWS), Dungannon, Ireland, was at the recent Hillhead show in Buxton, U.K., with two new products on display—the AggWash 300, a screening, scrubbing, sizing and sand recovery for recyclable aggregates, and the Terex AquaClear, the first water management treatment system from Terex.
“Terex Washing Systems is focused on bringing to market products that deliver value to our customers and offer solutions that serve their needs,” Oliver Donnelly, TWS director, says. “The AggWash 300 and AquaClear we brought to Hillhead do just that. Customers to the stand were excited to see up close these latest innovations and had the opportunity to speak to our technical experts to discuss bespoke solutions for their specific needs.”
The AggWash was designed to address higher production requirements for recycling customers and quarry owners, particularly in the construction, demolition and excavation debris recycling market. The system brings together rinsing, screening, scrubbing and sand washing capabilities on a single plant. Its portable format makes it suitable for green field applications, contractor use and temporary planning permission sites.
The AggWash incorporates two 16-foot by 5-foot triple deck Terex Cedarapids LJ-TS series horizontal screens, incorporating a triple shaft vibrator mechanism. The rolling chutes feature is designed for easy access for maintenance of the screen. The machine includes a logwasher with twin shaft angle adjustment to scrub gravel fraction and float out organics and adhered contaminants. There is a 6-foot by 4-foot trash screen for dewatering of lightweight contaminants from the logwasher, and the plant has an integrated sand plant incorporating rubber lined pumps and hydrocyclones available in various configurations and capacities.
In addition, TWS showcased its new water management offering, the AquaClear. The range includes clarifying tanks, flocculent dosing systems, filter presses and all associated equipment. The first ever installation is currently being fitted in the New England region of the U.S., where TWS is planning an open day for its customers later in the year. A new dedicated team is in place to lead this aspect of the business.
Water management systems are typically comprised of three main components. A floc dosing plant and thickener tank can be used to recycle up to 80 percent of the water used in the washing process. The next stage is to incorporate a filter press which hydrates this thickened sludge down to 25 percent moisture. The filter press is designed to eliminate the need for ponds as the sludge is hydrated to a material or cake, which can be handled by a loading shovel. This cake can be used as a lining or capping material.
“TWS are due to begin manufacturing the Terex AquaClear water management solutions in Dungannon, Northern Ireland, later this year, working alongside strategic alliance partners in the U.S,” Donnelley says. “We are already handling enquiries for AquaClear from Europe and North America markets. Through our strategic alliance, [for North American customers] we can send a filter press fully built up, rather than in its component parts in containers. Working with partners who have been in the industry for many years, we are confident that we have the technical capability to devise optimized solutions which present customers with a unique opportunity to maximize their return on investment.”
