Terex Washing Systems Bring Latest Technological Advancements to Market
Wed July 11, 2018 - National Edition terex
AquaClear enables TWS to offer end-to-end solutions for washing and water management from a single supplier. The range includes clarifying tanks, flocculent dosing systems, filter presses and all associated equipment.
The spotlight was firmly on Terex Washing Systems (TWS) at the Hillhead Show in Buxton, UK, with two new products on display — the AggWash 300, a screening, scrubbing, sizing and sand recovery for recyclable aggregates, all on one modular chassis, and 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. 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,” TWS Director Oliver Donnelly said.
AggWash 300 — A Game Changer in Wash Recycling
The AggWash was designed to address higher production requirements for recycling customers and quarry owners, particularly in the construction, demolition and excavation waste recycling market. The high performance solution brings together rinsing, screening, scrubbing and sand washing capabilities on a single plant.
While it's readily portable format makes it particularly suitable for green-field applications, contractor use and temporary planning permission sites, operators more used to static installations will still appreciate the small footprint and minimal site preparations required.
Paul McWilliams, TWS engineer manager, said, “In all cases, installation time is significantly less than conventional builds thanks to the high level of factory pre-fitting and connections. The no-compromise design ethos ensures maximum serviceability and performance despite numerous innovative features, including easily removed pumps, ready access to screening media and intuitive controls.”
AggWash 300 Highlights
The AggWash incorporates two 16 by 5 ft. (4.9 by 1.5 m) triple deck Terex Cedarapids LJ-TS Series horizontal screens, incorporating a triple shaft vibrator mechanism that provides high G force along with efficient oval motion. The compact installation height of horizontal screens compared to conventional inclined circular motion screens is conducive to the condensed working envelope of the AggWash 300. The “rolling chutes” feature provides easy access for maintenance of the screen.
The machine boasts a high capacity logwasher with twin shaft angle adjustment to scrub gravel fraction and float out organics and adhered contaminants. There is a 6 by 4 ft. (1.8 by 1.2 m) 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. Critical for ease of servicing and maintenance, the AggWash 300 also features walkaround access for maintenance.

AquaClear - The Icing on the Cake
In addition TWS showcased its new water management offering, AquaClear, enabling TWS to offer end-to-end solutions for washing and water management from a single supplier. The range includes clarifying tanks, flocculent dosing systems, filter presses and all associated equipment. The first ever installation is currently being fitted in New England, 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, which will ensure optimum equipment selection and specification for its customers.
Efficient Water Solutions
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 percent 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 percent 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.
Raising the Bar
“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.,” Donnelly said. “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 optimised solutions which present customers with a unique opportunity to maximize their return on investment.
“The reaction and interest to TWS new products and our stand presence was simply overwhelming. The flow of traffic onto the stand was incredible throughout the three days. We had the opportunity to meet with existing satisfied customers, prospective new customers, as well as many of our distributors from around the world. We were delighted to receive a large number of orders throughout the show, which is testament to our commitment to providing enhanced and unique washing solutions to meet customers' needs and demands,” Donnelly said.
