GRC / GFRC Fibre Choppers and Dispensers
Power-Sprays has developed a range of glass fibre cutting systems which enable GRC manufacturers to utilise Alkali Resistant glass fibre supplied in a roving format for Premix GRC production. In many locations, glass fibre supplied in rovings is an economic option due to the higher quantities which can be accommodated inside a standard shipping container (up to nearly 20 tonnes versus under 10 tonnes if factory chopped fibres are transported). Systems range from “hand-held” cutters through to multi-roving choppers mounted directly on the mixer and which control the quantity of glass fibre delivered by weight.
For Premix GRC product manufacturers who prefer to use factory cut “Chopped Strands”, Power-Sprays offers the “loss-in-weight” fibre dispenser with its unique “anti-bridge” system. This ensures a smooth delivery of the precise quantity of chopped fibres. The unit is also extremely low maintenance.
The addition of fibres to standard concretes to replace secondary steel mesh reinforcement to control cracks etc. in ground slabs and other applications is rapidly gaining popularity worldwide. For Volumetric Mixer operators, Power-Sprays has developed a truck mounted electric glass fibre chopper which can be regulated to provide glass fibres at the required rate of delivery.
