Experimental Grinding Machine "Retch Rotavita Mill SR 300"
Rotavita Mill SR 300
A grinder capable of crushing soft to medium-hard dried organic and inorganic materials, from coarse crushing to fine grinding!
The "Rotavita Mill SR 300" is a grinding machine capable of coarse to fine grinding of soft to medium-hard dried organic and inorganic materials, adjustable through screen and rotational speed settings. It can grind in batches or continuously. The rotational speed can be adjusted between 3,000 rpm and 10,000 rpm, allowing for condition settings tailored to the sample. It is suitable for sample preparation in laboratories as well as for prototype production in pilot plants and production facilities. All components, including the grinding chamber and hopper, are made of high-quality stainless steel. 【Features】 ■ High processing capacity suitable for batch use ■ Usable for pre-grinding to fine grinding ■ Variable rotational speed ■ Hold frame, rotor, and cassette can be detached without tools ■ Grinding with a 180° screen and grinder is ideal for hard and brittle samples ■ Distance rotor is suitable for heat-sensitive samples ■ Removable hopper for easy cleaning ■ Equipped with a motor brake ■ Grinding particle size is determined by screens with hole shapes ranging from 0.08 to 10 mm ■ Central locking system ■ A wide range of accessories available for various applications *For more details, please refer to the PDF document or feel free to contact us.
