Steel fibre dosing - INCITE AB
Dosing operation
Fibre dosing is filled with synthetic fibres from paper bags or Big-Bags. Desired quantity (in kg) can be adjusted on a box or from the control unit of the plant.
Fibres are fed directly into the mixer or via the aggregate transfer belt (sand, gravel). It is also possible to add the mixture directly into the mixer truck.
Design
Fibre dosing is designed in the form of a cylindrical container equipped with a spiral-shaped feed coil inside. This container is arranged on a rigid frame, in which 2 vibrating motors are attached to the supporting structure. Quickly changing the type of fibre used is possible by opting for additional containers, making the original container removable.
The equipment complies with EC and EMC directives.
Feeding capacity
Dosing capacity in kg/min varies depending on the type of fibre and the level of fibres in the dispenser. Filling capacity of the dispenser in kg also varies according to the type of fibre. Dispensers are suitable for dosing free steel fibres with L/D up to 60 or all types of glued steel fibres. Fibre dosing can also be used to measure the most common synthetic fibres. For the determination of free steel fibres with an L/D greater than 60, ask for a special quote.
BSC has the solution!
Standard version of the dosing units is designed for 220-400 V/3 pH/50 Hz. Dosing units for other voltages and frequencies can be supplied on request.
Weighing and control
Fibre dosing are mounted on load cells. We use negative weighing with two control system options, MS, and FS.
MS control system is a complete system with integrated weighing automation. FS control system is used for full integration of the unit into the concrete mixing computer system.
With the FS control system, the start and stop of the batching unit is controlled by the mixing computer. Accuracy for normal batches of ± 0.5 to 2 %. Accuracy depends on the type of fibre used.
Installation and starting up
Units are delivered ready for quick installation and instant connection.
They are installed on concrete slabs or steel constructions with counterweights of 5-7 tonnes to ensure the stability of the fibre feeder. Weather and wind protection is necessary for the synthetic fibre.
Today, there are more than 1000 fibre dosing units installed in more than 50 countries. Lists of references and contacts should only be made on request.
