Cement & Concrete Precia-Molen seals the deal
Precia-Molen installs a fully automated loading & weighing system for RockTron at its new £30m eco-mineral processing plant
At a cost of £30m RockTron’s new eco-mineral processing plant at Fiddler’s Ferry, near Widnes, Cheshire is now fully operational. Designed to process 800,000 tonnes/annum of both fresh and stockpiled fly ash (PFA), this has immediate implications for the UK’s cement and concrete industry in that RockTron can now offer a consistent supply of superior main constituents for cement and blended cements which can outperform GGBS on price. The environmental benefits are highly significant, as over 100 million tonnes of waste fly ash is currently dumped in long-term storage in UK landfills. Extremely effective, the technology developed by RockTron is designed to process 100% of both fresh and stockpiled fly ash. The company’s proprietary process offers five valuable new eco-minerals; two of the most significant are alumino-silicate solid glass spheres classified as Alpha & Delta. It is claimed that these two cementitious products will provide the single biggest environmental opportunity for the cement and concrete industries to reduce CO2 emissions over the next 25+ years.
The company has calculated that, in the UK alone, by using 500,000 tonnes of its eco-minerals on a one-to-one basis with
CEM1 cement, some 400,000 tonnes of CO2 could be saved. RockTron Alpha fully conforms to BS EN 450-1:2005 + A1:2007, and in fact exceeds the highest standards on particle size fineness and very low levels of LOI (Loss On Ignition) - the carbon content. The company’s main aim is to demonstrate that its recycled materials can outperform on quality, durability and price, especially when applied in the cement and concrete industry. From the outset of this high profile project, RockTron picked its build partners with care, commissioning market leading weighing specialist Precia-Molen to design and install a fully automated loading & weighing system at the Fiddler’s Ferry site, allowing vehicles to collect the eco minerals from the plant without the need for intervention of by our operators. Precia-Molen installed its widely regarded GeneSYS system which is fully integrated with the RockTron business management system. The GeneSYS system offers unique security and network systems allowing unparalleled levels of reliability and control; a solution which demonstrates Precia- Molen’s market leading expertise in driver operated system design, manufacture and installation.
