Industrial Sand Plants

Industrial Sand Plants are used to make extremely sharp classifications for the separation of <4 mesh sand. These plants employ various combinations of McLanahan's field-proven equipment, including Hydrosizers™, Hydrocyclones, Separators™, Log Washers, Coarse Material Washers, Fine Material Washers, Pumps, Attrition Cells, Dewatering Screens, Thickeners and Filter Presses, to create a complete wet processing solution for construction sands, specialty sands, industrial sands and even coal tailings.

Why McLanahan Industrial Sand Plants

Each Industrial Sand Plant is designed by McLanahan's experienced personnel based on decades of field results from many different applications around the world. Industrial Sand Plants are completely comprised of McLanahan equipment and engineered to provide an ease of maintenance.

How Industrial Sand Plants Work

Industrial sand applications come in all shapes and sizes, so they require in-depth conversations between equipment providers and end users in order to create an optimal process flow. Each area should be looked at for ease of transition and complementing the total system's performance.

  • Sizing - Screening off the unwanted coarse fractions
  • Pumping - Transferring slurry from one plant/process to the next, pressuring Hydrocyclones as part of a classification circuit, or in effluent disposal such as pumping Thickener underflow
  • Desliming - Removing the deleterious <200 mesh (75µm) materials prior to classification and after scrubbing
  • Classifying - Making sharp separations with Hydrosizers™  or Hydrocyclones
  • Scrubbing - Utilizing Attrition Cells to scrub the surfaces of the particles to improve turbidity, meet color requirements or improve downstream separation
  • Dewatering - Applying Fine Material Screw Washers, Dewatering Screens or Separators™ to achieve the level required for the next step in the process
  • Effluent Management - Thickeners can be built on the ground or Paste-style for recovery of 85% of process water
  • Waste Solids Management - Filter Presses to process fine waste solids from Thickener underflow into a cake that can be handled by conveyor of front-end loader
  • Sampling - Belt and slurry sampling can provide timely insight to the process performance and improve problem resolution response

Popular Applications for Industrial Sand Plants

McLanahan Industrial Sand Plants can be used to process a variety of specialty sands and minerals, including: frac sand, glass sand, filter sand, foundry sand, sports sand, concrete sand, plaster sand, mortar sand, coal, gold, silver, and garnet. They can also be used to remove lignite and other organic material and separate plastic from the sand, as well as slag beneficiation, closed circuit grinding and spiral circuit feeds.

Benefits of McLanahan Industrial Sand Plants

  • Make extremely shap classifications
  • Separate minerals according to their specific gravities
  • Ease of maintenance without needing to enter the tank
  • Lignite and other organics removal
  • Low cost to operate
  • Quicker ROI

Frequently Asked Questions

Why should I include McLanahan in the design process?

While the end user is the expert on the process, McLanahan personnel have significant experience, which can provide unique insight and a different perspective. McLanahan has been solving problems for decades by applying the right piece of equipment for the job to get the most out of the application.

I have some unknowns. Is there anything that can be done?

In addition to the lab services of sieve analysis, percent solids, attrition scrubbing, sink/float, sand equivalency and durability, Hydrosizer™ based classification, static and dynamic flocculation/settling and Filter Press testing, McLanahan can design and build a pilot plant to prove-out concepts.

What if I have some unique requirements on my equipment?

McLanahan manufactures its equipment in-house, and can provide fabrication and lining material substitutions that meet most requirements.
