An air classifier mill consists of several key components. The primary components include a grinding chamber, a classifier wheel, a fan, and a feed inlet. The grinding chamber houses the grinding elements, such as hammers or pins, which impact and reduce the particle size of the material. The classifier wheel, located above the grinding chamber, controls the size of the particles by adjusting the rotational speed and airflow. The fan generates the airflow required for particle separation, while the feed inlet allows the material to enter the grinding chamber.
The Air Classifier Mill is a vertical grinding mill incorporating an internal air classifying wheel with an independent drive.
The product is fed into the grinding chamber by either a feed screw or a pneumatic conveying system via a rotary feed valve.
The product is impacted by the high-speed grinding media, which causes the feed product to fracture and be thrown by the centrifugal force to the wall of the grinding chamber, which in turn, causes the product to fracture further. The fractured particles are entrained in the induced airflow liberating the outside wall of the internal baffle assembly, which is fitted with air baffles to laminar the airflow. The laminar airflow and particles pass to the internal classifier, which is rotating, in the same direction as the rotor disc. Oversized particles rejected by the centrifugal force applied by the classifying wheel are thrown to the inner wall of the baffle and move down by gravity and by the pressure created by the classifier. These oversized particles are then re-entrained into the grinding zone where further impact occurs.
The material to be crusher is conveyed from the hopper to the grinding chamber by the variable feed screw mechanism. The grinding occurs when the product meets a pin or bar-type rotor disc. As particles are reduced in size they are entrained by the Airstream which enters below the rotor and is carried up between the inner wall and shroud ring with baffles, the particles are then deflected by an air dispersion ring to the separator assembly. Acceptable product is drawn through the exhaust and is collected by a high-efficiency bag filter. Oversize particles are carried downward by the internally circulating air stream and return to Rotor for additional grinding.

Air Classifier Mill and pin mills are both used for grinding and classifying materials, but there are some differences between the two systems. Pin mills use rotating pins to grind and classify materials, while Air Classifier Mill uses a combination of impact milling and air classification. Pin mills use sieve holes to choose the powder size, but Air Classifier Mill uses air volume to choose powder so that can get a super fine powder.
When choosing an ACM, there are several factors to consider, including:
Material properties: The properties of the material being processed, such as hardness, brittleness, and moisture content, can affect the performance of the Air Classifier Mill.
Required particle size: The required particle size distribution will determine the type of Air Classifier Mill that is best suited for the application.
Throughput: The required throughput will determine the size and capacity of the Air Classifier Mill that is needed.
Energy efficiency: Energy efficiency is an important consideration, as it can affect operating costs.
Air Classifier Mills are relatively easy to maintain and require minimal cleaning compared to other grinding and classifying systems. Regular maintenance and cleaning can help to ensure optimal performance and extend the life of the machine. Some tips for maintaining and cleaning an Air Classifier Mill include:
Regularly inspect the machine for signs of wear or damage.
Clean the machine regularly to remove any accumulated material or debris.
Lubricate moving parts as needed.
Replace any worn or damaged parts promptly.

air classifier mill are used in a wide range of applications, including:
Food processing (grinding and classifying of spices, herbs, and other food products)
Chemical processing (grinding and classifying of pigments, dyes, and other chemicals)
Pharmaceutical processing (grinding and classifying of drugs and other pharmaceutical products)
Mineral processing (grinding and classifying of minerals and ores)
Plastic processing (grinding and classifying of plastic pellets and powders)
Recycling (grinding and classifying of various recycled materials)
Air classifier mills are versatile machines that offer several advantages over other grinding and classifying systems. They can grind and classify materials in a single operation, produce particles of precise and consistent size, generate less heat during the grinding process, and handle a wide range of materials. When choosing an ACM, it is important to consider factors such as material properties, required particle size, throughput, and energy efficiency. Regular maintenance and cleaning can help to ensure optimal performance and extend the life of the machine. Finally, it is important to follow appropriate safety precautions when using an ACM to minimize the risk of injury.
