FRAC SAND MINING classification( density separators) to produce coarse frac sand products( ie 30 / 50, 40 / 70), while other frac sand deposits are naturally fine and simply require scalping off top end material( at nominally 20 mesh) on the wet sizing screen and washing out the bottom end material( nominally-140 mesh) via larger diameter cyclones to produce an industry accepted‘ 100- mesh’ product – a product that has nominally 10- 12 % + 70 mesh and 10-12 %-140 mesh.”
Rautiola states that whether the plant requires a single- or two-stage coarse separation( McCloskey Washing Systems CombiSand™ range) or just a single stage of cyclone separation( McCloskey Washing Systems SandStorm™ range), MWS offers a solution fit for each application.“ The standard plants are fully inclusive starting at the feed hopper all the way through to the sand product radial stacker. The sizing screen is fully urethane-lined, double or triple deck, with a modular urethane panel layout on each deck for easy changing of panels. The pumps, cyclones, and density separators are all Weir Linatex ®, rubber-lined, and all piping is rubber or ceramic lined. The high frequency dewatering screens produce an absolute drip-free product onto the radial sand stackers, significantly reducing the amount of natural stockpile decanting time required for the sand to be dry enough to feed the dry plant.”
The systems are completely modular, and delivered to site in semi-assembled form, meaning the customer has absolutely no structural design or civil work to worry about, other than pouring a concrete pad on which to set the plant.“ Within five days of the MWS systems arriving on site, the plant can be producing spec frac sand, beginning the very short ROI period that comes with the production of valuable frac sand. McCloskey Washing Systems have designed these plants with the operator in mind: productive, safe, efficient, and accessible. All these factors come together with
EduMine the MWS Sandstorm ® and MWS Combisand ® sand plants.”
Terex Washing Systems offers flexibility
Terex Washing Systems( TWS) offers a broad product portfolio, including: modular wash plants, sand wash and fines recovery plants, log washers, hoppers, feeders, conveyors, dewatering screens, static screens, mobile, static and modular rinsers, as well as the addition of combination plants and water management.
The Terex Washing Systems FracStac can be seamlessly combined with the AggreSand in frac sand applications
The company told IM:“ One of the most specialised and diverse sectors within materials processing is the rapidly evolving world of industrial sands. High quality frac sand has become a much sought after commodity and whilst the range of clients is almost as diverse as the range of end uses for their sands we find they have a number of notable core requirements in common. Our systems have been used within the industrial sand sector and we are committed to understanding current and future market needs and offering equipment today which will solve tomorrows’ problems.”
TWS systems are also highly flexible to accommodate industrial sand applications beyond the fracking sector; for example sports sand product, filter sand, glass sand and foundry sands.“ From a single unit scope of supply through to a complete project solution TWS are ready to add value to your materials and to your operations.”
One TWS machine widely used in frac sand processing is the AggreSand ™ 206 wash plant, which offers feeding, rinsing / screening and sand processing together on one chassis, pre-wired and pre-plumbed. The AggreSand™ 206 can be delivered fully containerised, for streamlined transportation, swift commissioning and ease of relocation. It has a full electric drive making it a clean, environmentally friendly solution resulting in reduced operating costs. It also has the ability to integrate with other TWS equipment, depending on the customer’ s specific application. A seamless HMI communication system provides real time data on pressures, flows, amp usage, production data etc; while the machine has a fully automatic start up and shut down sequence.
In 2015, TWS also launched the FracStac™, at the time one of the world’ s first modular frac plants. At the launch, Sean Loughran, Director of TWS, commented:“ The use of high quality‘ frac’ sand in the process of oil and gas extraction has seen significant growth in recent years, especially in North America. With no signs of this trend abating, despite falling oil prices, coupled with the spread of this activity across the globe in the coming years, we believe this presents an exciting opportunity for TWS particularly with the announcement of our new product, the FracStac™. This truly modular plant allows customers to produce up to three grades of frac sand using proven technology and state of the art controls. Considering the extremely positive feedback we have received from customers and industry experts to date, I am confident this machine will be a game-changer in the frac sand industry.” IM
