The PAXAA HEPAX Classifier represents a highly versatile, energy-efficient system for the consistent separation of particles in 6-150 micron range. This separator has a compact design requiring minimal space for installation. Its simple circuit layout allows the highly flexible separator to be applied in a variety of systems and to fit any new process requirement or existing system. Installation time for the separator is minimized by its bolted-flange design.


  •   Features & Benefits:

    • Optimized and better separating efficiency over 1st & 2nd generation separators
    • Compact design allows easy retrofit into existing facilities
    • Saves on operating expenses on Low energy consumption
    • Durable, wear-resistant design minimizes maintenance
    • Consistent, high-quality product, regardless of variations in feed material, through easy-to-make changes in air flow and variable-speed rejector cage
    • Wear protection targets specific abrasion mechanisms for each separator component
    • Energy savings of the grinding plant with a fineness of separation up to 40%


  •   Standard specifications:

    • Direct Drive Coupling
    • A cartridge containing all bearings guarantees a long lifetime and protection against dust
    • Easy accessibility to all separator parts

  •  Working Principle:
    • The material is generally fed at the top of the separator. There are 1 or 2 gravity feed chutes or air slide feed chutes in order to improve the dispersion of the material on the distribution plate. Material falls and is dispersed in the circulating air by the distribution plate. The feed forms a thin cylindrical curtain of material in the classifying zone. The air stream is generated by an external fan. According to the type of circuit, it is possible to have 100% of fresh air, a part of the air recirculated or 100% of the air recirculated. Often, there are a primary air inlet, a second air inlet depending of the design. The airflow leaves the guide vanes almost tangentially to the outside of the cage. Material is arriving in the separation zone between the guide vanes (or louvres) and the rotating cage.

    The particles are driven by three forces: The centrifugal force due to the dispersing plate, the drag force due to the air flow and the gravity due to the mass of the particle. The drag force is trying to pull the material into the rotating cage. The centrifugal force is trying to push the material toward the guide vanes. It is the balance of these forces which induces a regular cut size of the separator.  This balance remaining steady because the material in the classifying zone has always the same radius of rotation, then the centrifugal force is the same in all areas. On the other hand, the air and material are normally distributed uniformly, the air velocity (then, drag force) remains equal.

    The coarse material doesn't enter in the rotating cage and goes out by gravity up to the bottom device (cone or other). The fine material enters in the cage and exits with the air flow by the upper or lower part of the separator.
