Mansfield Sand Meets Production Goals with
McLanahan HydrosizerTM Plant
Mansfield Sand Company Limited has been quarrying sand in North Nottinghamshire, England for more than 170 years. They are known countrywide as a supplier of materials for top class sports and sporting venues across the United Kingdom and Ireland. They supply sand material to 16 Premier League Clubs, 16 Championship Clubs and 120 other football league and non-league clubs for use in their stadiums and training ground facilities.
Besides sand for football stadiums, Mansfield Sand also produces a wide range of products for landscaping and equestrian uses, including championship golf and world class show jumping arenas, as well as asphalt sand, foundry sand, and sand for concrete and brick products.
Challenge
In 2014, Mansfield Sand wanted to upgrade their plant and control system to process a new deposit. They required a plant that would process 300 metric tons per hour of -65mm sand to manufacture their various products, including golf sand that
meets United States Golf Association standards, block pavior sand and asphalt sand.
In addition to this requirement, the local planning commission also set a noise restriction in place so the new plant would not disturb some rare birds nesting near the boundaries of the site.
It was at this time that Neill Rowland, McLanahan Applications Engineer, knocked on their door. He explained that McLanahan could offer them a HydrosizerTM sand plant that would produce five different products in one pass.
“One of the things that sold the plant was McLanahan’s technical ability to offer this,” said Rowland, noting that experience and confidence also played a role in Mansfield Sand’s decision to work with McLanahan.
Mansfield Sand was familiar with HydrosizerTM systems from an existing plant they had been operating for several decades, so they had already realized the benefits of HydrosizersTM for what they were trying to achieve.
“When you start getting down to really fine sizing, HydrosizerTM classification is really more efficient and more cost-effective,” explained Rowland. “The HydrosizerTM is the only piece of equipment suitable for the application to achieve the tight tolerances.”
Solution
McLanahan installed a HydrosizerTM plant incorporating McLanahan Pumps, Sumps, Hydrocyclones, SeparatorTM, Dewatering Screens and Blending System with the ability of blending to 1% accuracy to help Mansfield Sand meet the strict specifications required of their final products. The final products are discharged at less than 15% moisture, which creates stockpiling efficiency and allows for further drying processes.
To meet the requirements set forth by the planning commission, the entire plant is housed within a galvanized structure, clad and insulated to reduce the noise level. The plant’s components are also lined with rubber to protect them from the abrasiveness of the sand.
