A METHOD OF CONTROLLING FIBRE GENERATION IN THE MANUFACTURE OF MINERAL FIBRES FROM MINERAL MELT WITH THE AID OF CENTRIFUGAL FORCE AND AN APPARATUS FOR THE IMPLEMENTATION OF THE METHOD

摘要

The invention relates to a method for contolling fibre generation in the manufacture of fibres from mineral melt using several cooperating rotating wheels within a defibration unit. The melt route over the wheels is controlled by changing the position of one or more of the rotating wheels (1-4) within a defibration unit on the basis of the various factors affecting defibration process. The control may take place in such a manner that all rotating wheels are turned as a rigid entity around an axle parallel with the rotating wheel axles. Alternatively, one or more wheels are controlled individually in relation to each other. All position changes are essentially executed within the rotation level of the wheels. The invention also relates to the device used for implementing the method.
