Title:
PROCESS AND APPARATUS FOR CONTROLLING MINERAL WOOL PRODUCTION USING A CASCADE ROTOR
Document Type and Number:
WIPO Patent Application WO2004000742
Kind Code:
A3
Abstract:
A cascade spinner process is controlled by monitoring the torque ratio on one or more of the fiberising rotors (7, 8, 9, 10) which are rotating at a preselected speed, and adjusting the conditions on the first rotor (7) in response to deviations of the monitored torque ratio from a predetermined target torque ratio. The torque ratio is generally a ratio of torque on one rotor (usually the last rotor) to the torque on one or more other rotors. An apparatus for use in the process is also disclosed and claimed.
