Chopped Strand Fiber Feeder

The new Power-Sprays Chopped Fibre Feeder (patent application 0607670.7) is designed for the accurate dispensing of pre-cut glass and synthetic fibres.

The unit comprises a material holding hopper (the capacity depends on the bulk density of the fibre), a rotary valve which incorporates a unique agitating “anti-bridging” system to ensure that the fibres are kept moving, a delivery hopper and a feed duct, plus 3 load cells and programmable weigh batch control system.

The unit is operated by entering the weight required and pressing a “Start” button. Once entered, the target weight is stored ready for each batch. The control system incorporates an automatic “in-flight” correction system, which improves the accuracy of the weight dispensed with repeated operation.

The output rate can be adjusted by changing the speed of rotation of the rotary dispenser. Tests to date indicate that the accuracy of the unit is plus/minus 3% when dispensing a quantity of 2.27kgs of 13mm long glass fibres.
