Device for preparing fibre-filled polymeric compositions
摘要
A characteristic feature of the proposed device for preparing fibre-filled polymeric compositions having a fibre-chopping mechanism within a blender chamber and formed by a stationary plate with a draw-nozzle having a sharpened lip and by a rotary cutter adjacent to said plate, both the cutter and the sharpened lip establishing the chopping zone for the fibre passing through the draw nozzle. The cutter, while rotating, produces a vortex-type turbulent air flow, wherein the chopped fibre is intermixed with the polymer. The draw-nozzle communicates with the intake pipe for the fibre to feed through the draw-nozzle to the chopping zone.
