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.
