AIR CLASSIFYING MILL [ACM] REDEFINED Precision Grinding with Integrated Particle Size Control DP Pulverizers - Engineering Particle Size, Not Just Grinding

CONTROL THE PARTICLE, CONTROL THE PROCESS In modern powder processing, grinding alone is not enough. What matters is control—control over particle size, distribution, and consistency. Traditional mills grind everything and leave classification as a secondary step. That creates inefficiencies, broad PSD, and inconsistent results. Air Classifying Mills change the game. At DP Pulverizers, we engineer ACM systems that combine high-efficiency grinding with dynamic air classification, delivering precise, repeatable particle size in a single, integrated system. WHAT IS AN AIR CLASSIFYING MILL? An Air...

ACM systems operate based on the interaction of mechanical impact forces and aerodynamic classification forces. High-speed rotor generates: • Particle breakage 2. Dynamic Air Classification Airflow creates a centrifugal force field where: [Fine particles pass through Coarse particles are rejected Classifier Shaft & Bearing Housing Assembly Feed Hopper Fine Product Baffle Ring Seirated Lmei Screw Feeder Rotor Oise Feed Material Grinding Zone Rotor Shaft & Bearing Housing Assembly □P Pulveriser @ www.dppulveriser.com www.dpmills.com

Air stream transports particles upward into classification zone. Internal classifier wheel separates particles: | Fine ^ exits system Coarse ^ returns for further grinding Closed-loop system ensures: T Uniform particle size ° High efficiency • No over-grinding why ACMs are the preferred solution when: T Tight particle size control is required ° Over-grinding must be avoided ° Heat generation needs to be minimized ° High throughput...
