Air Classifying Mill

We are a trusted Manufacturer and Supplier of Air Classifying Mill. Air Classifying Mill, offered by us, performs classifying, grinding, collecting, and conveying operations. It also offers milling in a closed loop operation with inert gas or dry air if necessary. This flexibility enables the plant to handle explosive heat sensitive, explosive, or hygroscopic materials. This Air Classifying Mill consists of safety devices, electrical equipment, machine frame, rotor assembly, grinding chamber, and drives.
Principle
The material to be ground is conveyed from the hopper :

• to the grinding chamber by the variable fees screw mechanism
• The grinding occurs when the product comes into contact with a pin or bar type rotor disc.
• As the product size is reduced it is conveyed by an airstreams which enters below the rotor assembly via shroud and baffle ring
• 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 Dust Collector

Oversize particles are returned by the internal airstreams to the rotor disc for further reduction.
Safety Devices
All ACM mills are required with protection devices for safe operation. These measures include a safety switch on he cover of he grinding chamber. It is there by ensured that the drive motors cannot be switched on when the grinding chamber cover is open.

• Electrical Equipments : The plant is supplied along with a control panel and MCC, which provide the necessary interlocks and operating switches
• Machine Frame : The mill and all drive components are mounted on a rigid welded steel frame. All rotating parts are dynamically balanced floor smooth operation. There is no need for special foundation.
• Rotor Assembly : The assembly comprises of the following components: the separator wheel assembly, the rotor disc, bearing housing and the V-belt pulleys. The complete assembly is secured to the grinding chamber housing by four retaining bolts. All bearing is lubricated and are protected against ingress of ground product and dirt, moisture by means of special sealing rings.
• Grinding Chamber : The Grinding Chamber is sealed by a hinged cover held in position by hand wheels. When the hand wheels are released the entire cover assembly tilts upwards giving access to the milling components, these consist of: the air dispersion ring, the shroud and baffle ring, multiple deflector liners and the rotor assembly.
• Drives : All driven motors are fixed to the chassis and are easily accessible, power is transmitted by V-belts. A tachometer is supplied to indicate the speed and allows operator at a glance to select the correct speed for any pre-determined product fineness.

ACM Plant Includes

• ACM Mill for grinding and classifying.
• Dust Collector fully automatic Pulse Jet cleaning ensures dust free operation.
• Rotary Airlock used as an air seal and discharge material from dust collector.
• Fan to provide air flow through the mill and the collector for product conveying and cooling.
• Control Panel for sequential starting and stopping of the milling plant.
