RETSCH SR 300 and SK 300 rotor mills

The RETSCH SR 300 and SK 300 rotor mills are claimed to have been greatly improved with regard to performance, handling and flexibility. Due to their robust design, the rotor mills are suitable for applications in the laboratory as well as for small-scale production.

The speed of the rotor beater mill SR 300 has been increased and can be set between 3000 and 10,000 rpm, thus allowing for optimum adaptation to application requirements. Further features are the removable cassette and push-fit rotor that can be easily taken out for cleaning without using tools, just like the removable hopper. The cassette allows for almost 100% sample recovery. The grinding chamber, feed hopper and material inlet and outlet are made from high-quality stainless steel. The product is therefore suitable for use in pharmaceutical and food laboratories.

The cross beater mill SK 300 now also operates with higher speed, which can be set from 2000 to 4000 rpm. The grinding insert and rotor are as easily removable as in the SR 300. Both mills can be equipped with an optional cyclone, which improves material discharge, particularly for very fine particle sizes, and provides additional cooling of the sample.
