The plants range from uncomplicated mobile mixer and conveyor units to high production fixed operations with multiple silo and feeders utilising the latest control systems. Paddles are arranged in spiral pattern for thorough mixing.
Paddles are also adjustable outward on arms to three posi tions for wear compensation.
Division plates between compartments prevent intermixing of materials between compartments. A vertical silo is provided for each fine component, with a fluidising system for consistant flow. A low silo level sensor, coupled to the control system warns of filler depreciation and shortfall in the mix. The liquid feed, water and additives is fully piped to the mixer with supply tank, pump, meter and quick close valves via the mixing bar with carefully selected spray nozzles. Delivery rate is interlocked to the cement and aggregate feed rates with automatic alarms to control water addition within close tolerances.
