  • OVERVIEW

    Powerful pre-crushing

    The FRITSCH PULVERISETTE 25 is our heavy duty Power Cutting Mill for fast, reproducible pre-crushing of dry, soft to medium-hard or fibrous materials and plastic with a feed size of 120 x 85 mm and a throughput quantity of up to 85 l/h with a low rotor speed of 300 – 360 rpm with a high-torque 2.2-kW geared motor.

  • WORKING PRINCIPLE

    Unique grinding chamber geometry

    The sample material is comminuted according to the cutting principle of scissors between the cutting edges of the rotor and the fixed knives in the grinding chamber until the desired final fineness is achieved.
    Unique grinding chamber geometry: The grinding chamber is designed with minimal dead space and progressive cutting geometry between rotor and fixed knives. The sample material is continuously moved during comminution and cannot settle anywhere. In conjunctions with the special air flow, this is the basis for swift, blockage-free operation and fast cleaning without residue.

  • EASY CLEANING

    Unmatched easy cleaning!

    While you are still tightening screws on other mills, is your FRITSCH Cutting Mill already clean. Because the entire grinding chamber can be opened easily in seconds and both the rotor and the sieve can be simply be removed with simple motions. The housing and closing lid can be lifted back completely, and the grinding chamber lid can be completely removed from its hinges.

    The result: A completely open, empty grinding chamber with minimised dead space for simple quick cleaning and reliable protection against cross-contamination.

    FRITSCH–Advantage: The rotor of the Cutting Mill is easy to remove without tools. For quick cleaning in between, the rotor can also be turned by hand while the mill is open.

  • Applications / Solutions

    • Inspecting natural rubber analytically

      The production of homogenous composite samples is a prerequisite. Latex the white milky juice of the rubber tree, is sold in liquid or solid form as natural rubber. For the production of the liquid state, the tree juice is thickened and stabilized with ammonia. For the production of the solid state, the suitable chemicals are added to the juice of the plant and will coagulate. This solid is washed in various ways, dried and shaped mostly into thin slabs.
