The 1.5 in. (3.8 cm) minus material is fed into the Terex AggreSand machine and three clean gravels and two sands are produced.
Powerscreen Mid-Atlantic Inc. recently hosted an event premiering the AggreSand from Terex Washing Systems (TWS) at the Carolina Sunrock facility in Kittrell, N.C., as well as an event that followed at Carolina Sunrock’s facility in Butner, N.C., featuring the Matec System.
In Kittrell, approximately 155 guests saw shot blasted rock — hard granite rock indigenous to the area — fed into the Powerscreen Premiertrak 400 jaw crusher at 24 to 30 in. (61 to 76 cm). After being crushed down to a 4-in (10 cm) minus product, the material was fed into the Powerscreen 1000 Maxtrak equipped with a 40 in. (102 cm) cone for secondary crushing, and then fed to the Powerscreen Warrior 1400X equipped with a 12-ft. x 5-ft. (3.7 x 1.5 m) two-deck screen box. This process reduced the size of the shot rock to 1.5 in. (3.8 cm) minus and was ready for the Terex AggreSand wash plant. All of these machines work together to create five finished products, three types of clean gravel and two types of sand.
The Terex AggreSand system combines aggregate washing and screening with sand processing on a modular chassis. It brings together Terex Washing Systems components in a modular design. The Terex AggreSand has multiple applications including virgin aggregate; manufactured sand; sand and gravel; crushed rock; crusher dust; scalpings; iron ore; other mineral ores and construction and demolition waste material.
At Carolina Sunrock’s Butner, N.C., location, customers saw the Matec system in action that Carolina Sunrock purchased from Powerscreen Mid-Atlantic earlier in 2013. The Matec is a completely automated system designed for recycling waste slurry water from an aggregate wash plant. It removes the silt and clay from the slurry water and produces a dry silt cake and then sends the clean filtered water back to the wash plant for use. This eliminates the need for any settling ponds at the quarry and saves the customer the expensive maintenance costs that come with these traditional ponds.
The system at Carolina Sunrock consisted of a filter press, thickener tank, buffer tank, flocculant dosing station and clean water tank. Matec is a world leader in custom designed water treatment systems. Based in Italy, Matec has installed more than 1,000 systems worldwide, with more than 75 working in the United States.
Also during the event, Powerscreen Mid-Atlantic demonstrated the new Trakpactor 320SR impact crusher.
The Trakpactor 320SR is a mid-sized horizontal impact crusher redesigned to offer operators and contractors excellent reduction and high consistency of product shape for performance in quarry and recycling applications. The crushing chamber features a 44.5 x 31.5 in. (1130 x 800 mm) feed opening, hydraulically assisted CSS adjustment, four bar rotor and twin apron design and hydraulic overload protection as standard. New to this model is an optional fully independent hydraulic pre-screen, which improves fines removal and reduces chamber wear costs.
The plant features rapid set-up time, a fuel-efficient direct drive system and excellent output potential of up to 352 tons per hour (320 tph). The plant features a recirculating conveyor, which rises for transport, allowing more ground clearance under the machine when moving on site and loading for transport. A main feature of the Trakpactor 320SR crusher is the quick-detach post-screen section that converts it to a standard Trakpactor 320 unit.
“We were very happy with the success of our recent open days here in North Carolina,” said Mark Keenan, sales manager of Terex Washing Systems and Matec product lines of Powerscreen Mid-Atlantic Inc. “It gave us a great opportunity to showcase our various machinery to our customer base. The main emphasis for the shows was the official U.S. launch of the Terex AggreSand and we think this machine will be very popular in the U.S. market. The ease of set up and installation due to its modular design enables us to provide the customer with a complete turnkey solution, which can be moved from one site to another in a short space of time. We feel like Terex Washing Systems have really set themselves apart from the competition with the modular concept and look forward to installing their products with many of our customers.”
