The ZM 300 type mill can be widely used for soft, semi-hard, hard, brittle and fibrous samples.

The touch screen display enables simple user-friendly operation.

Adjustable parameters: grinding time and rotor speed. The grinder has an extremely powerful motor, which ensures that the sample can be ground in a very short time.

Grinding is carried out by a rotor consisting of several knives (teeth), rotating at high speed, and a stationary circular screen surrounding it. The teeth shred the sample, which passes through the circular sieve into the collection container. After grinding, the sample can be easily removed together with the collection container (cassette).

The grinder is easy to clean, the rotating rotors and circular sieves in the device are replaceable, so the particle size of the final product can vary over a wide range.

Recommended combinations depending on the quantity of the sample:

for normal use, the 900 ml collection cassette (accessory), or one of the rotors listed below and a circular screen with a suitable hole size are required.
in the case of larger samples, a 3- or 5-liter external collection container (Cyclone) can be installed on the device. The grinder can also be equipped with a feeder with a vibrating tongue, which ensures uniform dosing of the sample.

"but with 1 (900 ml) cartridge. With touch sieve controller. Grindable samples: soft, semi-hard, hard, brittle and fibrous samples. The particle size of the outgoing sample depends on the hole size of the circular sieve used (0.12 - 6.0 mm). 80% of the sample falling through the circular sieve placed around the rotor will be less than half the hole size of the sieve. Loadable max. size* < 10 mm Final fineness* < 40 ?m The speed can be changed between 6,000 and 23,000. Rotor diameter: 99 mm Thanks to the particularly fast grinding, the sample is subjected to the lowest possible heat load. Graphic display, software with intelligent menu system, easy to use. Automatic door closing. Power: 1,750 VA. Voltage: 230-240 V / 50Hz. Size: 452 x 431 x 426 mm. Weight: 38 kg. Standards: CE."
