Terex to unveil new washing solutions at Hillhead

Terex Washing Systems (TWS) says aggregate producers can look forward to more innovative ways to wash sand, gravel and C&D waste thanks to its two new offerings, which will be officially launched at Hillhead 2014, in Buxton, England, this month. Hillhead will provide the stage to showcase the Terex Aggresand lineup to include the 165 (up to 250 tph) and the latest addition, the new, larger Aggresand 206 (up to 400 tph), as well as the Aggrescrub 150 (up to 150 tph).

The Aggresand wash plants from Terex Washing Systems include sensors, providing the operator with information on water pressure, cyclone feed pressure and power consumption.

The Aggresand 206 wash plant is the larger model of the recently launched Aggresand line and comprises a 20-ft. x 6-ft. screen with two- and three-deck options. Customers will benefit from the unique design, which includes full containerization of the machine for ease of transportation, rapid set-up time, pre-wired and pre-plumbed plug-and-play componentry, isolated spray bars and an HMI control system. In addition, the level of serviceability within the Aggresand wash plant range is unrivaled, according to the company, with innovative features such as rolling chutes and rolling centrifugal pumps. TWS has also included sensors throughout the machine, providing the operator with information on water pressure, cyclone feed pressure and electrical power consumption, making the operation and management of the machine highly efficient.

High-attrition scrubbing
The second innovative product to be unveiled at Hillhead 2014 is the Aggrescrub 150, particularly suited to the C&D recycling market. Key benefits for customers include the improved wear characteristics, reduced costs, and the ability to effectively scrub aggregates and float out clays/silts/lights (wood/plastics) on one chassis. In addition, there are a number of paddle options available, including the traditional hard-wearing Hardox blades in 15- and 30-mm variances, as well as a new high-manganese steel option.

It shares many of the innovative features of the Aggresand line, including modular design, quick-and-easy setup, pre-plumbed pipework, pre-wired electrics, an HMI control panel and a web-frame chassis design.

The hull acts as a scrubber and also as a water bath. The TWS Aggrescrub 150 model is fitted with a newly orientated DW062 (6 ft. x 2 ft.) trash dewatering screen, which dewaters any floated-off trash including plastics and organics. The scrubbed aggregate is rinsed and sized on a DW125-2D (12 ft. x 5 ft.) two-deck screen, to produce three clean aggregate products for stockpiling.

Seamless integration
Another unique benefit to customers is the ability of the TWS Aggresand wash plants and Aggrescrub 150 plant to combine to provide the perfect solution for customers dealing with recycling applications, as well as pit owners with high agglomerations of clay.

The innovative, intelligent and user-friendly control system on both plants allows full integration between the two systems through the connection of a single plug-and-play cable. Through this control system, seamless communication allows the plants to work as a single entity with all interlocks, including start-up and shutdown sequences automatically synchronizing, which further minimizes the amount of on-site installation and commissioning required.
