ACM GRINDING SYSTEM

          

 

                 

The Air Classifying and Grinding System ACM series are well designed to grinding and classifying of different materials such as power coating,resin,pigment ,fine chemical and heat sensitive materials.
Main Characteristics:
High efficiency
Low temperature grinding
Easy cleaning
Excellent performance
No air pollution
24 hours continue working
Parts in contact with materials made by stainless steel.
 
The materials feed into the grinding chamber by a variable speed feeder.
The particle size reduces by impact of a pin disc and to teeth ring in a air current area.
The right sized powder pass through the variable speed blade classifier into the high efficiency cyclone collector.
From the cyclone collector,the powder pass through a centrifuge sieve to ensure that all the powder are in right size before weighting and packaging.
An air jet pulse bag filter clean the air by special filter and collect the under size powder.

Their working principle :

Product is fed into the grinding chamber by either a feed screw or a pneumatic conveying system via a rotary feeder valve.

Impact by the high speed grinding media causes the product to fracture and be thrown to the wall of the grinding chamber by centrifugal force. This, in turn, causes the product to fracture even further. Fractured particles are entrained in the induced airflow liberating around the periphery of the rotor disc which spirals upwards around the the outside wall of the internal baffle assembly (itself containing air baffles to help laminate 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 then move down by gravity and by the pressure created by the classifier. These oversized particles re-entrain into the grinding chamber where further fracture can occur.

This recycle action continues until all the particles pass through the classifier wheel. Product being emitted from the classifier is conveyed in the process airstream where it is either collected in a cyclone or enhanced by further classification in a cyclonic classifier

  • Temperature controlled grinding
  • Constant Output
  • Tight particle size distribution
  • Easy clean with the unique side opening design
  • Particle size control through fully adjustable rotor speed, classifier speed, airflow rate and feed rate.
