THE PRODUCT IN FOCUS

Model overview

A fixed-speed mill for versatile sample preparation

A 2.2 kW drive, double-acting cutting bars and optional cyclone collection make the SM 200 a versatile choice for soft, medium-hard, tough, elastic and fibrous samples. It adds power and collection flexibility while retaining straightforward operation at 1,500 rpm.

Feed must be below 60 × 80 mm. Choose a rotor, hopper and bottom sieve around the sample’s shape, cutting behavior and analytical requirements. The published fineness range is 0.25–20 mm; actual results depend on the material and method.

PERFORMANCE & OPERATION

Features. Operation. Handling.

Cut. Screen. Collect.

Rotating blades shear the feed against stationary cutting bars. The parallel-section rotor applies a strong cutting action, while the six-disc rotor uses spirally arranged reversible hard-metal plates to cut in sequence. Material leaves the chamber through the bottom sieve once it can pass the openings, limiting residence time.

Double-acting cutting bars increase the number of cutting events. A parallel-section rotor produces 18 cutting events per revolution. Use gravity discharge for suitable samples, or the optional cyclone and suction combination to improve removal of light material and help cool the sample and cutting tools.

Access for cleaning and safe operation

Smooth internal surfaces, removable sieves and a push-fit rotor simplify cleaning and sample recovery. The hopper folds back for chamber access and the rotor removes without tools. An engine brake, central locking and electronic safety checks control access: operation is prevented with the door open, and the door remains locked while the motor is running.

APPLICATIONS & METHODS

Build the process around the sample.

Biological, agricultural and food samples

Explore preparation of plant material, straw, wood, animal feed, feed pellets, food, spices, nuts and suitable bone or fish samples. Check moisture, toughness and temperature sensitivity when setting up the method.

Polymers, textiles and recycling

Typical cutting-mill samples include PET preforms, plastics and polymers, plastic toys, foils, rubber, resins, leather, paper, cardboard, textiles, cables, electronic components, refuse-derived fuel and other heterogeneous waste. Pharmaceutical products and material mixtures are additional areas to review.

Some applications include lignite, aluminum slag or nonferrous metal-containing samples. These require a material-specific review; they do not establish suitability for arbitrary hard metal or mineral pieces.

TOOLS & CONFIGURATION

The right tools for the task.

Rotor and cutting-tool materials

Choose a parallel-section or six-disc rotor. Stainless steel and steel configurations for heavy-metal-free preparation are available; tungsten carbide is also listed among cutting-tool materials. Match cutting bars, plates and the complete contact-material arrangement to contamination limits.

Rotor selection for cutting and shearing

Feeding and screening

The universal hopper suits many routine samples; the long-stock hopper handles elongated feed. Stainless or heavy-metal-free steel bottom sieves are offered with trapezoid openings of 0.25, 0.50, 0.75, 1.00 and 1.50 mm, and square openings of 2, 4, 6, 8, 10 and 20 mm.

Bottom sieves with different aperture sizes

Collection and installation

Collection choices include a 5 L receptacle, optional 30 L receiver and 0.25 or 0.5 L collecting units. Receiver volume is not a working batch or throughput rating. The optional cyclone supports receivers of 0.25, 0.5, 1, 2, 5 or 30 L. It can improve discharge, cooling and throughput for suitable light or heat-sensitive samples; validate the complete airflow and collection setup.
