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.
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.
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 Mansfield Sand’s door. He explained that McLanahan could offer them a HydrosizerTM sand plant that would produce five different products in one pass.
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.
McLanahan also provided an Ultra Fines Recovery System to recover fines down to 40 microns to extend the life of Mansfield Sand’s lagoon system.
Since commissioning the HydrosizerTM plant, Mansfield
Sand Company has not received a single customer complaint due
to the performance of the equipment. The plant’s modern control system gives Mansfield Sand the ability to adjust the product to meet consumer demands.
In four years of operation, the HydrosizerTM plant has proven to be both stable and reliable. It produces a consistent 280 mtph, and to date, the plant has produced 2 million tons of sand for Mansfield Sand Company. Furthermore, the Ultra Fines Recovery system has doubled the life of their lagoon by allowing Mansfield Sand to capture the fine material.
Overall, Mansfield Sand is pleased with the HydrosizerTM plant and Ultra Fines Recovery System.
“Our process plant continues to manufacture our premium quality sands to Mansfield Sand’s exacting standards,” said Richard Abraham, Managing Director of Mansfield Sand. “The partnership between Mansfield Sand and McLanahan has rested on the McLanahan team’s awareness of the importance we place on the reputation of our products and our respect for their experience. The partnership had a lot to prove, and it proved to be a great success.” March 2019 - Issue 55
