McLanahan continues to support aggregate customers across the UK and Europe.

McLanahan is continuing to support aggregate customers across the U.K. and Europe with wet and dry processing solutions for natural sand and gravel applications and for recycling aggregate from C&D debris streams. With compact, modular plants for rapid deployment and fast setup on site as well as bespoke equipment tailored for specific applications, McLanahan ensures producers get the right solution for their processing needs.

One example that highlights McLanahan’s commitment to its customers is the recent sale of an UltraWASH Modular Wash Plant and UltraCRUSH Modular Crushing Plant to Cemex, one of the U.K.’s largest aggregate producers. McLanahan’s process engineers and design engineers worked closely with Cemex on the design of the plant to ensure it was the right solution for the Shepperton, U.K., site.

The plant features an UltraWASH consisting of a feeder, primary rinsing screen, slurry pumps, hydrocyclones, dewatering screens and product conveyors. The raw aggregate material will be introduced into the primary rinsing screen by the feeder. The primary rinsing screen will separate the feed into 20 mm and 10 mm sizes and discharge them onto corresponding product conveyors for stockpiling.

Any material over 20 mm will be directed to the UltraCRUSH Cone Crusher to be reduced in size before being recirculated back into the UltraWASH for further processing.

The sand fraction, along with the water from the primary rinsing screen, will fall into a sump underneath the screen, from where the slurry will be pumped up to a bank of hydrocyclones. They hydrocyclones will classify the material to meet the required specifications by separating out fines and silt from the product-sized sand. The sand will discharge from the hydrocyclones onto a dewatering screen to remove excess moisture before stockpiling.

The McLanahan UltraWASH and UltraCRUSH plants will allow Cemex to produce essential building materials to support local infrastructure demands.

“We are proud to be continuing to form strong relationships in the U.K. with companies like Cemex, and we look forward to seeing where this partnership can take both companies,” said Donal McNicholl, McLanahan’s Director of Sales for the U.K and Ireland.

McLanahan is also committed to supporting customers who need bespoke solutions, whether for new builds, plant upgrades or retrofitting equipment into existing setups. An example of this can be found in just one of McLanahan’s many recent screen sales.

New Milton Sand and Ballast needed to replace a primary rinsing screen that had reached the end of its usable life, but the company did not want to change the main frame on which the screen was installed.

McLanahan engineers worked with New Milton Sand and Ballast to design an Inclined Screen that was tailored to fit into the existing plant structure. They also interviewed New Milton Sand and Ballast about its pain points with the old screen to determine how to best design the screen to meet the company’s needs.

The solution was a 1.8m x 5m double-deck Inclined Screen outfitted with spray bars on the top and bottom decks that were tailored to alleviate challenges New Milton Sand and Ballast had with its old screen.

One of these challenges was the clearance between the screen decks, which made changing the screening media a hassle. McLanahan increased the clearance between the top and bottom deck to improve maintenance access for New Milton Sand and Ballast.

Another issue the company had with the old screen was increased wear from the sand slurry mix hitting the first few panels of the screen media on the bottom deck. McLanahan decreased the aperture size in the first few panels to allow for even wear.

McLanahan also increased the aperture size of the spray nozzles so that they wouldn’t clog up from the grit and organic matter in the recycled water New Milton Sand and Ballast uses for rinsing the aggregate on the screen.

It was these and other screen design updates reflecting McLanahan’s commitment to supporting its customers that impressed New Milton Sand and Ballast the most throughout the project.

Besides supporting customers throughout the design, installation and commissioning phases, McLanahan also provides after-sales service and support for the lifetime of the equipment. This after-sales support includes everything from supplying spare parts, to sending technicians to perform plant audits and make recommendations for operational improvements, to offering field service assistance for component repairs or replacements.
