Air Classifying Mill | Pulvocron

Air Classifying Mill

The Pulvocron air classifying mill utilizes high-speed impact and internal particle size classification to produce fine powders with a narrow size distribution. Adjustable operating conditions, including tip speed, air flow, and classifier speed provides control over resultant particle size, material temperature, and capacity. Thermally conditioning the inlet air stream provides optional heating to simultaneously dry and mill wet solids, or cooling to reduce resulting material temperatures.

HIGHLIGHTS

  • Resulting particle size averaging as low as 3-5 micron, depending on the material being processed
  • Unique horizontal cantilevered design provides easy access for maintenance, reducing downtime
  • Incoming air can be heated or cooled to simultaneously dry or cool while grinding
  • Hinged access door offers quick and easy access to internals for maintenance, inspection, and cleaning
  • Optional multi-plate configuration available for additional milling
  • Wide variety of wear-resistant materials available to mitigate component wear
  • Internal independently driven classifier instantaneously separates particles into on-size and overs for recycle

Feed material enters the grinding chamber at a steady, controllable rate. Feed is dispersed by the primary hammers, then impacted between the beaters and the stationary liner. Material enters the internal dynamic classifier where it is classified by mass into oversize and on-size. Oversize particles are rejected and recycled back to the inlet for reprocessing. On-size particles pass the classifier and are conveyed to the ensuing cyclone or baghouse separator.

When needing to simultaneously dry and grind your feed material, we employ an air heater to heat the inlet air stream. This provides the ability to dry and grind simultaneously, drying along the constant rate drying portion of a typical drying curve. High-speed milling breaks apart materials, exposing additional surface area for more efficient drying.

The Pulvocron air classifying mill is just one of the size reduction technologies we employ to develop industrial process systems that meet your application requirements. At Bepex, we are committed to developing the best industrial process systems using the right technology. Between our proven industrial process equipment and decades of experience serving the industry, we are able to design a fine grinding system that is right for you.
