Majac Acucut High Energy Air Classifier

As requirements in the pharmaceutical industry continue to ask for tighter particle distributions, additional steps such as on-line classification may be required. The Acucut air classifier utilizes dual stage operating controls to ensure sharp cuts and narrow band particle size distributions typically below the 10 micron range. This permits control of maximum and minimum particle size diameters with unparalleled accuracy. With precise control of the air flow and rotor speeds this unit will produce the same sharp cuts each time, every time. The high energy dispersion also ensures that the maximum percentage of fines is reclaimed. Easily operated, cleaned and maintained, the Acucut air classifier keeps downtime to a minimum.

Options are available for effective control of product contamination, protection against corrosion, handling abrasive materials and classifying adhesive powders. The Acucut air classifier is ideal for chromatography materials, alumina, silica, toner and metal powders. Extremely high dispersive energy applied to the process material ensures unparalleled yields even with sticky and difficult to disperse products.

The Acucut air classifier is a forced vortex unit designed to disperse, then classify fine particles into coarse and fine fractions. High energy dispersing air enters the rotor radially around the entire outer edge. Feed material enters this dispersion air zone through an inlet in the rotor ring. Particles are acted upon by centrifugal and drag forces. Air carries the dispersed fines inward to the central fractions outlet, coarse move outward to the rotor periphery. Cut points are adjusted by airflow, rotor speed or both.

Advantages:

  • High energy dispersion
  • Ideal for temperature sensitive products
  • Reproducible results from batch to batch
  • Tight band widths/ distributions
  • High recovery on coarse fractions
  • Compact design
  • Easy cleaning
  • Easily fluidizes high density materials

Available options:

  • 316 or 316 L stainless steel construction
  • Nitrogen inerted systems
  • Abrasion protection

The Acucut is ideal for applications which require specific particle size cuts and tight distributions, such as DPI's (Dry Powder Inhalants) and parenterals.
