Hywell machinery air classifier mill is an air classifying mill with integrated grinding, classifying, conveying, and collecting operations for achieving ultra-fine grinding (up to 2 microns) depending upon the nature of the product.
Operating in the medium to fine particle size reduction range the delivery guaranteed, accurate particle size because of the highly efficient, variable speed dynamic integral air classifier and achieves a steep particle size distribution with minimum ultra fines.
This type of air classifier mill operates on the principle of impact grinding and employs high rotor speeds with a striking edge velocity of up to 120 m/s. the air classifier mill also named as air swept classifier mill.

Air classifier mill material would be conveyed by the feeding system evenly to the milling chamber, and would be impacted by a high-speed rotating beater, and also under the centrifugal force, it would impact the grinding track. By several different pulverization powers, the material would be milled into fine powder. The milled powder would go with air flow up to the classifying chamber. With the help of an adjustable classifier wheel, coarse powder and fine powder would be separated. The qualified fine powder would go through the wheel vane and then into the cyclone separator or dust collector, while the mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again. The air classifier mill to grinding the dry powder into 150-500mesh , so if it just want to get 20-100mesh dry powder, it can use the pin mill and cost also lower more.

Hywell machinery super fine air swept classifier mill had the following advantages over conventional solutions.
1. Air classifier mill gets fineness powder
Air classifier mill crush and classifying in one system. Required product size is achieved by the adjustment of the classifier wheel.
2. Air classifier mills have a compact structure
Small space occupation, low installation power, wide application, and high-performance cost.
3. Air-swept classifier mills have high milling efficiency constructure
Different beater designs, pin shapes, hammer shapes, and tooth shapes, for different materials.
Hywell machinery Air Classifier Mill is supplied for either batch process or for continuous operation. They are utilized in industries that produce fine powders where control of the particle size distribution is required. the air classifier mill systems are designed to handle both inert and explosive applications where venting or containment is required.

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 crushed 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.
Hywell Machinery is able to offer our WF Series air classifier mill with contact parts to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. Electrical parts of the control system of the powder Air classifier mill can be adapted to the customer’s needs.
