Finnish ready-mixed concrete producer Kymppibetoni has deployed two mobile concrete batching plants from Northern Ireland-based Rapid International for the production of wind farm foundations.
The Rapidbatch 120’s compact modular design is designed to be easily transportable and can be fully erected in one working day, reducing downtime. Installation can be carried out via a single crane lift and no foundations, and it features plug-and-play electrics.
The integral Rapid twin shaft mixer offers reduced wear with extra thick chill cast tiles and paddles and an aerofoil arm design.
The plant’s integral 3m³ Rapid twin shaft mixer batches up to 120m³ per hour of high-quality homogenous concrete. The mixer’s arm design allows fitment at either 60°/90° and creates an area of high turbulence designed to ensure a homogeneous mix, in a reduced timeframe.
Kymppibetoni required a mobile batching solution capable of withstanding the often harsh weather conditions faced on wind farm construction sites in Finland.
To ensure maximum output of concrete in adverse weather, the Rapidbatch 120 was fully winterised to include insulated composite cladding, lined doors and a heating system for aggregates, water and the integral Rapid twin shaft concrete mixer. Leevi Grönlund – process designer at Kymppibetoni Grönlund, commented that as a result of these measures: “The Rapidbatch has proven its applicability in our projects.”
Jarlath Gilmore, sales & marketing director at Rapid International, said the company has supplied a number of Rapidbatch plants for wind farm foundation projects around the world.
