Fritsch GmbH’s Milling and Sizing division, Idar-Oberstein, Germany, has introduced its new planetary mill, the PULVERISETTE 5 ‘premium line’. The new planetary mill is the next size up from the company’s previous PULVERISETTE 7 ‘premium line’, and features two grinding stations for bowls between 125–500 ml volume. It offers 2.2 kW drive power and centrifugal acceleration up to 64 g at 800 rpm, with a rotational speed of 1600 rpm for the grinding bowl.

The PULVERISETTE 5 is capable of grinding sample quantities of up to 450 ml at a maximum feed size of 10 mm, and is said to be ideal for wet and dry grinding of hard, medium-hard, soft, brittle and moist samples, as well as for mechanical alloying, mixing and homogenising. According to the company, it produces reliable results down to the ‘nano range’.

The new planetary mill has been designed to make small-scale grinding operations easy and safe. It incorporates a guided insertion mechanism to ensure the correct insertion of grinding bowls, and incorporates a safety mechanism for secure automatic clamping of grinding bowls within the mill. ServoLOCK is a user-independent, motor-driven locking mechanism designed to ensure that both the mill, the member of staff using it and the plant are protected during grinding.

In addition, if the machine detects an operating state not permitted for safety or quality, it will block grinding operations from beginning, and if an imbalance is detected during grinding it will shut off automatically. Depending on the material of the grinding bowl itself, which is detected via RFID chip, it is also said to automatically prevent users from setting grinding speeds which are too high for safety or for good results.
