Abstract: An apparatus for producing fibers from molten material includes a drive shaft rotatable about an axis, a slinger basket including a base, a side wall, and an interior void. The side wall extends axially upward from the base and includes a plurality of distribution holes. The interior void extends radially from the drive shaft to the side wall and extends axially from the base to an upper opening which extends radially outward from the drive shaft toward the upper flange. A spinner body is coupled with the slinger basket and includes a roof contacting and extending radially outward from the upper flange such that the upper opening is substantially unobstructed by the spinner body. A spinner side wall extends axially downward from the roof and includes a fiberizing region including a plurality of fiberizing holes provided therein.

Abstract: An additive injection system can be a part of a cementitious slurry mixing and dispensing assembly. The additive injection system can be used to inject an additive into an auxiliary slurry discharge conduit carrying a secondary flow of cementitious slurry produced in the assembly such that the secondary slurry stream is different from a main slurry stream discharged from a main slurry discharge conduit.
