McLanahan UltraWASH Plants

With a long history of designing, manufacturing and installing modular wash equipment, McLanahan’s line of UltraWASH modular wash plants are the latest line from the company. Engineered to include all McLanahan equipment that helps producers meet their process requirements, the UltraWASH provides the reliability, simplicity and efficiency that producers need from a modular plant.

All equipment that make up an UltraWASH plant, including the vibratory screen, hydrocyclones, dewatering screen, sump and pump, is based on the company’s well-known, field-proven designs. UltraWASH plants provide a quick, easy-to-install processing system. These modular wash systems are ideal for producers facing criteria such as planning permits, multiple locations, short-term deployment, or an unknown/variable feed stock (e.g. C&D waste streams applications) that make implementing a customized, fixed processing solution difficult.

Currently available in six sizes and configurations, the UltraWASH can produce up to three aggregate products and up to two sand products. There is a single process water feed point, as well as a single effluent discharge point.

McLanahan currently offers several additional configurations and add-ons to the UltraWASH, including:

  • Single or dual sand product
  • Feed preparation (log washer, blade mill, coarse material screw)
  • Attritioning module for specialty sand production
  • Organics removal module
  • Water treatment with high density or paste style thickener
  • Filter press for complete wastewater treatment

Ease of maintenance

McLanahan knows the importance of uptime, so the UltraWASH is designed with ease of maintenance in mind. The pump trolley service platform allows the pumps to slide out from underneath the chassis for greater access when performing maintenance activities, such as changing the impellers or replacing casing liners. A foot pedal for lifting the discharge pipe from the pump and a locking mechanism for then holding the pipe aloft offer the clearance needed for the pumps to roll out on the trolley service platform unrestricted.

A retractable feed conveyor is an option that allows easier access to the feedbox when it comes time for servicing. Rather than lifting personnel to the height of the feedbox to perform maintenance, we bring the feedbox to them. With the push of a button, the conveyor will retract and the feedbox will be brought closer to ground level, making it both easier and safer for your personnel to maintain the UltraWASH.

Another maintenance feature included in the UltraWASH Modular Wash Plants is easier access to the aggregate hood. Simply remove the section of grating from the walkway behind the aggregate hood, slide the aggregate hood back and reattach the grating in front of it. This creates a platform for accessing inside the aggregate discharge hood when needed.

Quick setup

Because modules arrive in individualized containers, they are quick to set up and easy to move around for different configurations. This also makes them easy to transport to other sites. Assembling each module is simple and takes less than a day to get the whole plant up and running.

McLanahan has carefully thought of all the details and features that will make maintenance and efficiency easier – including two truly unique features. The Eze-Riser allows the operator to cut pump maintenance time in half, and the Fines Forward Slide and Aggregate Discharge Hood are included to increase your efficiency.

Modular Plant For All Your Needs

UltraSAND Modular Sand Plants:

With the greater separation efficiency of Hydrocyclones/Separators™, the UltraSAND is proven to provide a higher product yield compared to stand alone processing equipment. Producers can achieve a much lower moisture content from the Dewatering Screen, depending on the characteristics of the sand.

UltraSCRUB Modular Scrubbing Plants

Capable of removing water soluble materials from the toughest of clays, McLanahan UltraSCRUB Modular Scrubbing Systems provide a flexible washing option for aggregate feeds. Arriving on-site in containerized modules, producers will benefit from the shorter lead times, quick set-up and ease of transportation offered by the UltraSCRUB.

UltraFINES Modular Fines Recovery Plants

UltraFINES Modular Fines Recovery Plants are a combination of a Sump, Pump, Hydrocyclones and a Dewatering Screen in a module that is specifically designed to recover fine solids from a wash plant effluent stream. The recovered material is conveyable and stackable, and is suitable for multiple industries, including sand, iron ore, coal recovery, ash, industrial sands, frac sand and more. UltraFINES modular plants recover fine solids to produce a standalone product and reduce the amount of solids reporting to the settling pond or downstream equipment.

UltraDRY Modular Dewatering Screens

The UltraDRY Modular Dewatering Screen has a quick set-up that can be easily added onto any new or existing equipment. The slow travel speeds of material through the Dewatering Screen allow for longer sand retention, which generate better drying time for a consistently dry product.

McLanahan’s Dewatering Screens use the highest G force on the market, which enables them to handle the largest loads. An optional pump add-on can provide ideal water placement for a cleaner product, while limiting water usage.

EcoPRESS Modular Filter Presses

EcoPRESS Modular Filter Presses provide the ability to optimize tailings management with the recovery of clean, reusable water. The EcoPRESS Filter Press can address many typical issues associated with fine material processing, including full slurry ponds/tailings dams, high material handling equipment repair costs, limited expansion capabilities, environmental permit restrictions, high waste material handling costs and limited water availability.

EcoCYCLE Modular Elevated Thickeners

EcoCYCLE Modular Elevated Thickeners provide a compact and modular solution for water recycling and sludge handling. EcoCYCLE Thickeners come complete with motor, pump, floc dosing station, control panel and control cabin.

Helping Customers Across The Globe

James Nolan, who owns Tri-Parish Sand and Gravel with his wife, Gail, has always been concerned about the cleanliness of the products they use in their ready mix facility. They strive to deliver quality products on the concrete side of their business, which starts with the material used to make those products. Tri-Parish Sand and Gravel is a dry mining operation located in Louisiana, USA. They produce C-33 concrete sand, pea gravel and #57 concrete gravel for use in their ready mix operation, Parish Ready Mix.

To better control the quality of their concrete products as well as lower their production costs so they could pass those savings onto their customers, the Nolans purchased land for dry mining their own sand and gravel. They looked at a few wash plants in different parts of the country for processing the feed and separating it into the various products needed at their ready mix facility.

In 2020, Tri-Parish purchased the McLanahan UltraWASH 6206 Modular Wash Plant that debuted at CONEXPO/CON-AGG in Las Vegas. Availability was a key factor in the purchasing decision. Tri-Parish needed a wash plant quickly, and the McLanahan UltraWASH offered an entire wet processing plant in one compact, modular unit that was ready to run.

“We bought the plant, and we’re very, very pleased with it,” James Nolan said. “It definitely does way more than they said it would do.”

While there are a number of modular plant solutions available in the market, McLanahan is one of the only companies offering both custom and modular washing solutions. This, combined with years of processing design knowledge, provides unmatched industry expertise in providing the correct solution for your application.

McLanahan Corporation was founded in 1835 in Hollidaysburg, Pa., USA. Today, the company is in its fifth and sixth generations of family ownership with offices that provide local service and support in Asia, Australia and Asia Pacific, Europe, Latin America and North America.
