Continuous measurement of gas pressure and temperature during grinding

For monitoring of thermal effects, physical and chemical reactions and much more directly in the grinding bowl

With the new EASY GTM Gas Pressure and Temperature Measuring System you can turn the Planetary Mills PULVERISETTE 5 and PULVERISETTE 6 of the FRITSCH classic line into analytical measurement systems.

Due to the continuous measurement of gas pressure and temperature, thermal effects as well as physical and chemical reactions or pressure variations can be monitored directly in the grinding bowl.

For this, simply insert the grinding bowl with the radio transmitter integrated in the lid, without any modification to the mill itself. The monitored data is transmitted to a computer via a receiver. The EASY GTMControl software included in the scope of delivery generates a graphical presentation of the measured values, which can also be offered as a PDF report and transferred to an Excel™ table.

The EASY GTM-System provides valuable information

  • Investigations in the area of mechanical alloying for the production of new amorphous and nano-crystalline materials
  • Monitoring and optimisation of grinding processes in industrial applications

The measurement of the grinding bowl temperature allows an integral statement on the process variable temperature, which takes account of the effects of all friction, impact and transformation processes. The continuous and highly sensitive measurement of the gas pressure in the grinding bowl enables the detection of very rapid reactions. The measured gas pressure describes, among other things, the interactions of the gas with the surfaces created during grinding (adsorption and desorption of gases).

Extremely rapid phase formations can be observed for the first time IN SITU as an adiabatic process without heat exchange with the system.

Technical data

  • Temperature measurement range of the transmitter component: -40 to 110 °C
  • Resolution of pressure signal: 1 mbar
  • Permissible pressure in the grinding bowl: 0 – 20 bar – measuring range up to 30 bar
  • Operating time with fully charged battery: approx. ½ year continuous operation (depending on operating temperature)
  • Radio transmission: 2.4 GHz standard

High final fineness for large quantities
Fast and fine - Disk Mill PULVERISETTE 13 classic line - Particularly ideal for medium particle sizes in the areas of mining and metallurgy, glass industry, ceramics industry, soil research, rocks and soils. The Disk Mill PULVERISETTE 13 classic line is the ideal instrument for fine grinding of up to 150 kg per hour of soft to hard-brittle and temperature-sensitive solids – even in continuous operation. The maximum feed size per piece is approximately 20 mm edge length, the final fineness is freely adjustable between 12 mm and 0.1 mm. Powerful fine grinding The material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth. The ground material automatically falls down through an output gap into the collection drawer. The desired final fineness can be defined from the outside by changing the gap width. Your advantages - High throughput up to 150 kg/h - Fine grinding down to 0.1 mm - Grinding disks are available in 5 different materials - Metal-free grinding with grinding disks made of zirconium oxide and a polymer interior coating of the mill - Simple operation - Fast grinding disk

Dynamic Image Analysis – the fast alternative to sieving
Results in less than 5 minutes in a measuring range from 5 µm – 20 mm If you perform many and frequent sieve analyses, the Particle Sizer ANALYSETTE 28 ImageSizer is the ideal, time-saving alternative in just three steps: Add the sample, start the measurement, read the result. Without a preparatory and concluding weighing, assembling the sieve stack and time-consuming cleaning. And with substantially reduced follow-up costs, as there is no need to calibrate or purchase new sieves. Additionally, you receive besides the equivalent results about the particle size distribution, also valuable statements about the particle shape. The measuring time depending on the sample quantity, is under 5 minutes and the result is available immediately digitally for further processing. Your advantages compared to classical sieve method - Short measuring times of less than 5 minutes - No time-consuming manual weighing - Fast and safe cleaning of the measuring system - Result immediately available due to the software - Easy handling Display of

FRITSCH Cutting Mill PULVERISETTE 19 – optimized for cannabis processi
The FRITSCH PULVERISETTE 19 with Cyclone is an efficient instrument to quickly comminute large volumes of cannabis. Plant material is fed into the FRITSCH Universal Cutting Mill PULVERISETTE 19 through a large funnel for fast throughput. Due to an efficiently designed cutting geometry of the rotating cutting edges of the rotor and the fixed knives in the grinding chamber, the sample material is automatically moved and comminuted increasingly fine by shearing forces between the knives. The negative pressure in the cyclone ensures a continuous flow through the cutting rotor and the selected sieve cassette for precise final fineness in a narrow particle size range. It prevents sample material from escaping during feeding and opens up new possibilities in the cannabis processing. The high throughput of up to 60lbs per hour is supported by large collection vessels of up to 65 liters. While you are still tightening the screws on other mills, your FRITSCH Cutting Mill is already clean. The design of the grinding chambers in these mills results in minimal dead space and exchangeable

Innovative measurement of the pH value during particle sizing
This method covers fluctuations much more effectively than the zeta potential As the first supplier ever, FRITSCH has now developed a way to measure the pH value of the dispersion liquid almost directly in the measuring unit. The new pH sensor is installed as a module in the dispersion bath and connected to the Laser Particle Sizer. It continuously measures the pH value during the measurement and automatically transfers the determined values to the software for documentation. This method covers fluctuations much more effectively than the zeta potential and offers many advantages, especially in the area of research and development. The pH value is much broader, especially with measurements in the field of nano-suspensions. Its monitoring provides valuable information about how and when a chemically inert material, for example, reacts to alkalis, depending on the environment. If the curve is unstable and varies during measurement, the pH value helps with stabilization and interpretation. The pH measurement process now introduced by FRITSCH
