ABSTRACT:
An apparatus for producing mineral fibers by low pressure air fiberization having a housing defining a substantially toroidal air chamber formed of a forward vertical wall and having a substantially circular central opening, an annular slot provided around the central opening, and an air inlet provided at a portion of the chamber. A cup-form spinner is mounted on a substantially horizontally oriented shaft arranged to be rotated. The spinner is mounted in front of the forward wall of the plenum and with the open end facing the forward wall. A duct is provided to direct molten slag into the spinning cup which ejects molten slag into an air stream emitted from the annular slot of the chamber, thereby producing mineral fiber of excellent quality.
