OVERVIEW

Ideal for comminution with 2 working stations

The Planetary Mill PULVERISETTE 5 classic line, with two working stations delivers fast and reliable, due to the particularly high-energy effect of the grinding balls, loss-free grinding results of hard, medium-hard, soft, brittle, tough and moist materials down to colloidal fineness. Depending on the desired final fineness, can the grinding be performed dry, in suspension or in inert gas. Besides for comminution, the Planetary Ball Mill can be utilized for mixing and homogenizing of emulsions and pastes or for mechanical activation and alloying in material research.
WORKING PRINCIPLE

Comminution according to the Planetary Principle

The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. To achieve this, the grinding bowl, containing the material to be ground and grinding balls, rotates around its own axis on a main disk whilst rotating rapidly in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding bowl. The grinding balls then cross the bowl at high speed and further grind the sample material by impact against the opposite bowl wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process. Due to the rotational speed of the main disk – up to 400 rpm – achieves the PULVERISETTE 5 classic line a centrifugal acceleration of up to 22 g.

SAFE GRINDING BOWL CLAMPING

Reproducible grinding results and absolutely safe grinding bowl clamping

The constant transmission ratio, the regulated rotational speed and precision quartz timing, ensure exactly reproducible grinding results. The Safe-Lock System, which is delivered with a torque wrench, enables simple and safe clamping of the grinding bowls - absolutely risk-free.
MEASURING GAS PRESSURE AND TEMPERATURE

EASY GTM classic line - Gas Pressure and Temperature Measuring System

With the new EASY GTM Gas Pressure and Temperature Measuring System you can turn the Planetary Mill PULVERISETTE 5 classic line into an analytical measurement system.

Configure your Planetary Mill PULVERISETTE 5 classic line exactly to your specific application

The Planetary Mill PULVERISETTE 5 classic line with 2 working stations, operates with 2 respectively 4 grinding bowls of sizes 80, 250 or 500 ml, which turn with a transmission ratio of 1 : -2,19 relative to the main disk. To achieve best grinding results, grinding bowls and grinding balls are available in various sizes and 6 different materials.
Contamination of the samples due to undesired abrasion can be directly prevented. For grinding in inert gas, for mechanical activation and alloying are gassing lids recommended.

Applications / Solutions
- Comminution of organic material
  
  Milling organic samples can be challenging, because they may contain oils or resins. A sample of hops is comminuted in this video using our Planetary Mill PULVERISETTE 5 classic line.

- Influence of properties of grinding bowls in the planetary system
  
  A clean and constant wear on the inner grinding bowl surface is a question of the amount of grinding balls and size, material amount and size (coarse or fine), the grinding condition like wet or dry grinding, the grinding duration and the adjusted rotations of the planetary system.

- From “Boulder” to Nano-Particles
  
  Medium-hard to hard materials with edge lengths up to 95 mm can be pre-crushed with the FRITSCH Jaw Crusher PULVERISETTE 1 so an additional fine comminution with many FRITSCH mills is possible.

- Additives for dry milling
  
  During a dry grinding, often only after a short grinding period hygroscopic material tends to stick. A second factor causing this is the static charge respectively adhesive powers of fine particles.
  more information
- Crushing concrete coarsely and fine
  
  Concrete is a complex material, which its characteristics due to its composition and as a result of the systematic addition of additives can be adjusted very differentiated. However, this results in the demand to monitor this composition for two reasons: in order to ensure the desired useful properties and also to ensure the quality of the mixture.
