Description: The rotating disc is the core rotating working component of the needle mill (vertical impact mill), widely used in the starch industry. Together with the stationary disc, its high-speed rotation achieves the impact-driven separation and disintegration of starch and fiber in the slurry.
Driven by the main shaft at high speed; once material enters the center, strong centrifugal force accelerates the slurry and throws it outward.
The moving needles on the disc repeatedly strike the stationary needles on the stationary disc, breaking cell walls so that bound starch peels away from the fiber, achieving pulping and dissociation.
Controls outward material transport, determining the grinding effect, capacity, and slurry-to-residue ratio.
A disc base, moving needles (grinding pins), needle seats, positioning and locking bolts, and a main-shaft hub; the whole assembly is dynamically balanced and is mainly made of wear-resistant stainless steel.
