FIBRE DOSING Fully Automatic Equipment For Steel and Synthetic Fibres

Steel Fibre Dosing Equipment Power supply The doser is filled with steel fibres from paperbags, boxes or big-bags. The desired batch, in kg, is set on a weighing instrument or in the mixing computer. The fibres are fed into the mixer, on to aggregates on belts, into a skip in the weighing bins or to the mixer outlet. Direct addition into the truck mixer is also possible. In standard execution, the dosers are built for 220 400V/3ph/50 Hz. Dosers adapted for other voltages and frequencies can be supplied upon demand. Design A cylindrical container, with a spirally shaped feeder coil on its inside,...

Steel fibre dosing data: D (mm) Capacity (kg/min*) Doser content (litre**) * The capacity varies, depending on type of fibre ** Theoretical volume. The doser content in kg varies, depending on type of fibre. Installation example from Ishibe-Machi, Japan. Dual dosing equipment for optimisation of steel fibre concrete production for flooring and shotcrete. Installation example from AB Fardig Betong, Sweden. Dosage feeder mounted on a concrete slab. The fibres are transported via a conveyer belt in connection with the discharge from the mixer. 3

Synthetic Fibre Dosing Equipment Power supply The fibre doser is filled with synthetic fibres from paperbags, boxes or big-bags. The desired batch, in kg, is set on a weighing instrument or in the mixing computer. The fibres are fed into the mixer, on to aggregates on belts, into a skip in the weighing bins or to the mixer outlet. Direct addition into the truck mixer is also possible. In standard execution the dosers are built for 220 400V/3ph/50 Hz. Dosers adapted for other voltages and frequencies can be supplied upon demand.

Synthetic fibre dosing data: D (mm) Capacity (kg/min*) Doser content (litre**) * The capacity varies, depending on type of fibre ** Theoretical volume. The doser content in kg varies, depending on type of fibre. Dosing unit type MD500SX Tray with up to 400 kg PP-fibre content. Feeding capacity: up to 15 kg/min. Dosing unit type MD500SX Dosing of pucks of macro fibres. Tray content 600 kg. Feeding capacity: 20 kg/min. Dosing unit type MD400 Filling from big-bags of 150 kg. Tray capacity max 250 kg of PP-fibres. Feeding capacity: up to 15 kg/min. 5

Additional Equipment Special equipment / custom made systems Continuous dosing in kg/min for specific applications, for example units like the MD500SX/MD250C (below) or the SF1200SR with a sieve system and a by-pass path for extremely difficult fibres (to the left). Other sizes available upon demand. SF1200SR for dosing of loose steel fibres with L/D above 60! Buffer belts for large fibre quantities The addition of fibres from the buffer belts to the fibre doser can follow automatically or manually. Standard buffer capacities can vary from 1 to 8 big bags. Other sizes available upon demand.

Conveyer belt as intermediate batch storage The fibre batch is pre-fed on to and stored on a conveyor belt. The addition to the aggregates or into the mixer can than flow rapidly, or with a controlled speed to achieve a pre-mix. The belt is equipped with frequency-controlled drive. Vertical fibre elevator This specially developed bucket elevator allows a rapid (2.2 m/s) vertical transport of steel fibres, up to 30 m height. Fibres are fed into the weighing bin or directly into the mixer. Over 50 elevators are installed world-wide. Dosing of loose macrofibres Fibre doser, type Macroflex 1000....
