Analysis and Optimization of Wet Grinding Processes
from Laboratory to Production Scale
THEORY | Analysis and Optimization of Wet Grinding Processes – from Laboratory to Production Scale
User seminar with the goal to impart the theoretical background and the function of agitator bead mills. The effect of important operating parameters on the grinding process will be discussed and various procedures will be explained.
Practical tests on the LabStar laboratory mill as well as on a production size machine will be used to demonstrate the effects discussed. Afterwards we will address the topics of particle size characterization and stabilization of suspensions (dispersion of ultrafine particles into the nanometer range).
Seminar Content:
- Introduction to the NETZSCH Business Unit Grinding & Dispersing
- Characterization of Successful Comminution – Terms and Definition
- Overview of Grinding-media-free Dispersion Systems – Mixing, Wetting and Dispersion
- Overview of NETZSCH Grinding Systems, Agitator Bead Mills
- Effect of various Process Parameters
- Model of the Stress Energy and the Stress Rate
- Effect of the Dwell Time Distribution
- Selection of the Grinding System and the mode of operation
- Rheology
- Grinding Media Selection and Scale-Up
- Calculation – from Laboratory to Production Scale
- Tour of Assembly area
- Summary and Discussion
Optional (can be arranged after consultation):
- Limits of Wet Grinding, True Comminution and Gentle Dispersion
PRACTICAL TRAINING | Implementation of laboratory tests – planning, performance, analysis, documentation
After the user seminar, the theoretical knowledge acquired is now applied directly to our machines. In working groups with a maximum of 3 participants each, various tasks are carried out on different machines.
Here, the test materials undergo either true comminution or dispersion. During this workshop, advisors are available to provide support, but these are hands-on tasks for the participants.
Content:
- Execution of a complete laboratory test, including setup and preparation of the test facility
- Changing of the barrier fluid and measurement of the no-load curve
- Filling of the machine with grinding media
- Recording of a pump curve
- Recording of important characteristics curves
- Sampling and sample preparation for analysis of the test results
- Processing of the sample material, including sampling and sample preparation
- Characterization of the starting material
- Troubleshooting basics
- Handling Iris V3 system control
- Documentation and discussion of the results
