Planetary Mill

PULVERISETTE 5

premium line

OVERVIEW

FRITSCH Planetary Ball Mills – high-performance all-rounder in routine laboratory work
The Planetary Mill PULVERISETTE 5 premium line with 2 grinding stations is the ideal mill for fast wet and dry grinding of hard, medium-hard, soft, brittle and moist samples as well as for mechanical alloying, mixing and homogenising of larger sample quantities with reliable results down into the nano range – and an absolutely secure automatic clamping of the grinding bowls.

WORKING PRINCIPLE

Comminution according to the Planetary Principle

The comminution takes place primarily through the high-energy impact of grinding balls and partially through friction between grinding balls and the grinding bowl wall. To achieve this, the grinding bowl, containing the material to be ground and grinding balls, rotates around its own axis on a main disk rotating in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to bounce off the inner wall of the grinding bowl, cross the bowl diagonally at an extremely high speed and impact the material to be ground on the opposite wall of the bowl. The grinding bowls reach twice the speed of the main disk during this process.

Due to the extra strong 2.2 kW drive power and centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1,600 rpm) are high-performance grindings down into the nano range possible.

FEATURES
  • Extra strong 2.2 kW drive power and extremely high centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1,600 rpm)
  • Maximum operational safety due to ServoLOCK clamping of the grinding bowls
  • Blocking of the mill in the event of impermissible operating states
  • Automatic shutoff function if an imbalance occurs
  • Reliable bowl detection via RFID chip and optimization of grinding speeds via RFID-Chip
  • Safely guided insertion of grinding bowls
  • Safe opening in the event of overpressure
  • Intuitive touchscreen operation with colour display
  • Simultaneous processing of up to 4 samples
  • Useful capacity  up to 2 x 225 ml
  • Up to 8 programmes can be saved, software MillControl (optional), USB inter face for transmission of process parameters
  • Extensive accessories for simplifying your daily work
MORE SAFETY DUE TO SERVOLOCK
  • Grinding has never been safer: With the completely brand new ServoLOCK clamping of the grinding bowls and the automatic check of the fastening of the bowls inside the mill, man and machine are optimally protected. In the event of impermissible operating states, the machine blocks the start of a grinding – and if an imbalance occurs it automatically shuts off.

    The revolutionary ServoLOCK is activated with a single hand motion by pressing down the clamp. The actual clamping is motor-driven by the mill. Your advantage: each grinding with always same conditions without screwing or other manual fastening.

SOFTWARE MillControl - EASY GTM
  • Automatic control and monitoring – Measurement of gas pressure and temperature
    The Software MillControl enables the automatic control and monitoring of the Planetary Mill PULVERISETTE 5 premium line. The actual rotational speed and power consumption are checked and documented. By using two EASY GTM-bowls with special lid and transmitter you transform your PULVERISETTE 5 premium line into an analytical measuring system for monitoring pressure and temperature during the grinding process.

EQUIPMENT / ACCESSORIES
  • Configure your Planetary Mill PULVERISETTE 5 premium line exactly to your specific application

    The grinding bowls of the Planetary Mill PULVERISETTE 5 premium line are available in the sizes 125 ml, 150 ml, 250 ml, 420 ml and 500 ml. This gives you total flexibility for optimal adjustment to your specific sample volume. If you would like to grind four samples simultaneously, simply order four grinding bowls, each with 125 ml or 150 ml volume and 2 stacking rings.

    To achieve the best grinding results and for direct prevention of contamination of the samples due to undesired abrasion, all grinding bowls and balls are available in different materials. For grinding in inert gas and for mechanical activation and alloying premium line gassing lids are recommended – quickly and safely.

FRITSCH AR-APP
  • Augmented reality (AR) is a technology that superimposes a computer-generated image on an user’s view of the real world, thus providing a composite view. In soccer broadcasts, for example, you’ll find augmented reality when superimposing distances of free kicks using a circle or a line. We took advantage of this effect and programmed an app for you. Simply download the free-of-charge app in the app store of your mobile device and place our instruments as the PULVERISETTE 5 premium line live in your laboratory.
