Abstract: Apparatus, systems and methods for controlling the amount of air introduced into the forming hood area in the manufacture of mineral fiber insulation products utilize one ore more cyclonic separators to remove great quantities of moisture, heat and air before laying fibers down on a collection surface, such as a conveyor. In some embodiments, binder is applied (if at all) only after the cyclonic separator, so that any presence of binder chemicals in emissions or downstream forming components is minimized. The system reduces the many air, moisture and energy inefficiencies existing in present forming systems.

Abstract: A differential axle assembly includes an axle housing having a pair of opposed openings. A differential gear set includes a pair of side gears. Each of the side gears are supported within one of the opposed openings. A plurality of pinion gears engage the side gears. A hypoid ring gear is rotatably supported within the axle housing and a pinion shaft is supported by the hypoid ring gear. The pinion shaft supports the pinion gears in engagement with the side gears. The hypoid ring gear includes a cylindrical inner diameter having a pair of axially spaced inwardly facing annular surfaces and the axle housing includes a pair of axially spaced outwardly facing annular surfaces. The hypoid ring gear is rotatably supported within the axle housing by a pair of roller bearings positioned between the annular surfaces.
