McLanahan Sand Washing Plants process sand from its raw state into products that meet various specifications. The process requirements vary depending on the input and desired output, but plants typically scrub, liberate, deslime, wash, classify, decontaminate and dewater the sand, as well as process the effluent stream that results.
For customers who are interested in maximizing yield and producing precisely graded products to the end-user's needs and specifications, it is more likely that a custom sand plant is the correct solution. Whether the sands are natural or manufactured, fine or coarse, well or poorly graded, or required for specialty applications, McLanahan can offer a plant specifically designed to suit your needs.
McLanahan is best known for creating process solutions to address the specific needs of each customer's application. We have one of the largest ranges of robust, field-proven equipment, and we are constantly innovating. Our background and expertise in applications is second to none.
Depending on the application, McLanahan can perform lab scale tests on materials, including sieve analysis, percent solids, attrition scrubbing, sink/float, sand equivalency and durability, Hydrosizer based classification, static and dynamic flocculation/settling and Filter Press testing.
With our proprietary simulations, in-house lab and industry expertise, you get a plant designed specifically for your site with capacities to match your need. Our expertise is the envy of the industry, so when you couple this with one of the largest ranges of equipment offerings, we can offer a solution.
Sand Washing comes in many forms and covers a range of feed and products produced, including construction aggregates such as concrete, asphalt, mason, mortar, and plaster sands; sports sands such as for golf courses, ball parks, and race courses; industrial sands, such as glass, filter, foundry, and frac; specialty sands and materials such as anti-skid, roofing granules; deligniting/organics removal; and soils washing for environmental projects.
First, consider the following questions: What do you have? What do you want to make? If the answer is a very specialized gradation and a difficult natural sand deposit, then consider a Recipe Plant. If the answer is a manufactured sand and you are making concrete sand all day every day, then an Ultra Sand Plant or Modular Wash Plant may be your answer.
Many other factors, such as available investment, local competition and expanding markets, will influence this decision. Through a process of elimination starting with the simplest configuration, McLanahans experienced personnel will guide you through to the best options.
Ultra Sand Plants, which utilize Dewatering Screens, Pumps and Cyclones, offer greater separation efficiency and provide a higher product yield that can be reused almost immediately due to the effectiveness of the Dewatering Screen. Ultra Sand Plants are commonly used to wash and dewater industrial and specialty sands, as well as asphalt, concrete and masonry sands.
For high-quality sand that meets strict specifications, look no further than McLanahan Recipe Sand Plants. These sand plants make use of every grain of sand to offer customized blending for concrete, foundry, glass and plaster sands. The resulting sand product is consistent, uniform and will meet even the tightest of specifications.
McLanahan In-Line Blending Sand Plants provide high product yields, offer flexible blending options, produce drier products and improve product consistency. They are simple to operate, create accurate splits and are field-proven.
McLanahan designs each of its Frac Sand Plants to meet the specific needs of each customer. Using field-proven McLanahan equipment, Frac Sand Plants can be designed for classifying, desliming, dewatering, pumping, scrubbing, sizing, tailings management and waste solids management. McLanahan Frac Sand Plants are engineered to make the critical separations required for frac sand. They produce the highest product yield at the lowest moisture.
Classifying Tank Based Sand Plants can create multiple products from a single feed as well as remove slimes and excess water. Feed material enters the Sand Classifying Tank first, and sand grains settle in sections according to size down the length of the tank. Valves at the bottom of each section release the grains into one of several flumes used to create a primary, secondary or tertiary product, depending on the application. The discharged products are then dewatered by Dewatering Screens and/or Fine Material Screw Washers. The addition of Cyclones and/or rising current water can be used to deslime the feed.
McLanahan Industrial Sand Plants are designed with a combination of McLanahan equipment to provide extremely sharp classification of various industrial sands. This equipment can include Attrition Cells, Dewatering Screens, Hydrocyclones, Hydrosizers, Filter Presses, Fine Material Screw Washers, Pumps, Separators and Thickeners.
Although Portable Plants, which can be wheel-mounted or skid-based to provide an ease of transport, are limited in capacity, they do not limit the process. Portable Sand Plants can be used for classifying, dewatering, sizing and removing oversize and organics from feeds to produce aggregates, construction and demolition materials, and specialty sands.
McLanahan Ultra Fines Recovery Plants can recover +400 mesh material for use in many industries. UFRs are especially well-suited in the aggregates industry for effluent streams containing <100 mesh fractions and for recovering valuable coal from effluent streams in the coal industry.
