AIR CLASSIFIER MILL - ACM

The cylindrical casing is vertically split into a lower ultra-fine milling zone and an upper air classifying zone. Raw materials are introduced via a speed-controlled screw dosing mechanism on the inner wall, ensuring continuous, volumetric, and uniform feeding into the milling chamber to maintain a dynamic flow balance from the source.

The grinding disc and classifier wheel are driven independently by separate drive assemblies and bearing housings. Upon entering the milling zone, materials encounter high-frequency mechanical impact, shearing, and intense friction between the high-tip-speed disc and peripheral liners, instantly pulverizing into ultra-fine particles.

Milled particles are carried upward into the classifying chamber, where the dynamic rotor utilizes the balance of centrifugal force and centripetal drag to separate the fines. Qualified products pass through the discharge pipe to the cyclone collector, while oversized particles recycle along the inner wall back to the milling zone for re-grinding.

Breaking away from traditional integrated structures, the machine utilizes an innovative separate shaft design paired with a completely independent bearing housing layout to block heat accumulation at the source, efficiently dissipating bearing friction heat in real-time. This ultimate thermal control delivers unparalleled mechanical stability while eliminating risk of high-temperature lubrication failure, consequently perfecting its capability to meet rigorous industrial demands for 24/7 non-stop, zero-downtime, and continuous high-load production lines.

Featuring a shaft-within-a-shaft structure that integrates the classifying shaft inside the grinding shaft, this coaxial design is ideal for the ultra-fine milling of high-cleanliness materials like medicines, food, and battery components. Furthermore, because the classifying wheel bypasses direct elbow discharge, it significantly reduces outflow resistance, making the system highly efficient for processing sticky materials.

Featuring a unique center-feeding system on the grinding disc, this mill delivers greater kinetic energy and accepts larger input sizes up to 50mm, eliminating the need for fine pre-crushing. Its extended classifying chamber leverages gravity classification before centrifugal sorting, ensuring superior fineness, strict control over large particles, and exceptional drying performance for high-moisture materials.

Furthermore, it applies the "stone-on-stone" milling principle to process needle-shaped materials with an impressive 15:1 aspect ratio, while the composite wear-resistant grinding blocks and gear rings guarantee an extended service life.

Engineered for strict fineness control and precise top-size cuts, this mill features an innovative horizontal classifier wheel design that breaks away from traditional vertical structures. The horizontal orientation creates an exceptionally uniform flow field and stable centripetal balance at high speeds, eliminating air short-circuiting or oversized particle bypass. This breakthrough delivers unparalleled classification precision and an ultra-narrow Particle Size Distribution (PSD), making it the ideal solution for high-fineness demands in advanced materials and fine chemicals.

Featuring dual-sided grinding blocks on the disc, this mill expands the milling zone for more thorough processing, making it highly effective for material deagglomeration and particle shaping. To streamline maintenance, the feeding side incorporates a hinged device for effortless opening and cleaning, while the upper classifier can be customized with a quick-open wheel for rapid servicing.

Furthermore, the internal aerodynamics are optimized to ensure no areas fall below a flow velocity of 6m/s, completely eliminating material accumulation and internal residual zones.
