Choosing the Right Dry Grinding System for Pigments

Dry pigments are powders with various hardness or stickiness features depending of their origin, composition or production process. Milling them is thus a real challenge specially because this step strongly influences the end qualities of the product as dispersibility, coloration intensity and appearance of the surfaces.

The target of this webinar is to give you criteria for selecting the right grinding technology appropriated to your pigment.

During this webinar, 3 different milling system will be presented. Their operating process, their specific advantages and the influence of the working parameters will be described and discussed.

Rapid Formulation Development, Feasibility Studies and Screening for Paints, Coatings and Inks with the Dual Centrifuge DeltaVita® 1

In the area of formulation development or in quality control, many companies make do with modified planetary ball mills, sample shakers or special mixers on a very small scale. This practice certainly allows predictions to be made from very small sample batches, but it provides results with very limited transferability to production scale on agitator bead mills.

The DeltaVita® 1 dual centrifuge is based on the advanced development of a classic centrifuge. In contrast to a conventional centrifuge rotor, the rotor is equipped with two symmetrically arranged rotary plates. The rotary plates can be fitted with different adapters for holding sample vessels with volumes between 2 ml and approx. 150 ml.

Extensive investigations have shown that this universally applicable laboratory instrument for comminution, dispersing and mixing processes can be used to make predictions regarding pigment quality, grindability, formulation stability, the correct grinding media size and the achievable product quality. In addition, it was shown that these results can be transferred with very good reproducibility and accuracy to results obtained with agitator bead mills using the same grinding media.

Industry 4.0 - Increasing the efficiency of grinding and dispersing processes

Production processes in industry are being optimized more and more in order to become more energy efficient, safer, more environmentally friendly and to increase their production capacity. Digital solutions such as Notify can make a decisive contribution to this.

Notify is a software solution with which "real time monitoring" of machine and process parameters, i.e. a display in real time, can be realized on a computer, cell phone or tablet. Notify is independent of the operating system of the end device. The only basic requirement is an Internet connection and a corresponding connection to the machine via a gateway, which is already available at NETZSCH Machines with the state-of-the-art IRIS control system.

With Notify, process managers or operators can obtain an overview of the operating states and process parameters of the machines in production from anywhere at any time. With the appropriate authorization, threshold values or limit values can be defined that define a critical operating state. Notify then sends "notifications" to a defined group of recipients so that the machine operator can intervene in the process before a shutdown occurs or the product is damaged and economic damage occurs.

Notify thus makes a direct contribution to increasing process and operational safety. In addition, downtimes and rejects are avoided. Employees responsible for processes can thus optimize time sequences and analyze and optimize process sequences with the digital data pool via dashboards.

Furthermore, maintenance and service intervals can be optimally planned and machines and systems can be ideally utilized.

Machine safety - NETZSCH has solutions to build safe machines and ensure good handling!

If solutions that ensure safe operation of mixers are not practical, then you are limiting the handling with the machine.

Nevertheless, nothing is more important than protecting machine operators from machine hazards and avoiding risks or even accidents!

For this reason, we constantly check the latest regulations and guidelines regarding machine safety and adapt our design so that the machines are safe and easy to operate. This applies to the mechanical construction as well as to hazards due to the processing of flammable substances according to Atex.

In this webinar, you will get an overview of the topic of machine safety for mixers and dissolvers and we will show examples of solutions that NETZSCH has developed for this purpose.

Efficient Mixing of High Viscosity Product with NETZSCH PMD VC Mixer

For production of pasty products like texture coatings, fire retardant coatings and other highly viscous product, with traditional multi-shafts using multi mixing tools on the same shaft, the need to prevent “slinging” of materials to the vessel wall meant slow powder feeding rate and poor wetting. Hence when all the powders are added, it will required a long dispersing time to reach desired dispersion quality.

This webinar will show how the Netzsch PMD VC Mixer with its, unique vessel and large mixing arms design, and in combination with a single high speed shaft and mixing tool enable a fast controlled powder feed for an efficient production of high viscous product.

Milling of coatings into the ultra-fine range

The quality of coatings is related to different criteria regarding weathering, mechanical resistance, application behavior as well as the decorative or coloristic attributes like the hue, chroma, color strength and the gloss.

All of these properties are influenced by the formulation and the homogeneity of the coating systems as well as the particle size distribution of the pigments.
The desire for higher energy efficiency and for increasing production capacities but also more and more expectations regarding the quality of modern coating systems necessitates an optimization of process parameters in the grinding and dispersing process.

New developments regarding equipment used for pre-dispersion, pre-grinding and fine grinding as well possible improvements regarding efficiency and product quality will be discussed in this webinar.

Powder handling - modern solution for TiO2, pigments and dust free area

The handling of solid raw materials when mixing initial slurries and suspensions today requires increasing attention to eliminate or reduce the operator exposure and contamination of production the environment.

Recent ECHA regulations are moving towards to more stringent rules on the safety and handling of powdered raw materials, nevertheless manual handling by bags is still a widespread operation in the paint industry.

NETZSCH is glad to offer a wide range of modern, high-performance solutions for the automatic and semi-automatic handling of the powders used for paint &coating manufacture, such as carbon black, titanium dioxide and color pigments.

Flexible solutions for clean and efficient powder discharge will be evaluated for different cases, such as the handling of high volume single products, fast discharging of problematic products, multi-purpose pigments handling with a focus on a fast cleaning and reduced contamination.

The aim is to help our customers to find solutions for creating dust free environments that are safe areas for operators whilst also to improving the efficiency and operation of the industrial processes.

All these solutions can be integrated with the range of pre-dispersion systems offered by NETZSCH both traditional HSD or the newer generation of inline disperses.

Pre-Grinding Mill – ProPhi

ProPhi is the NETZSCH solution for the fast and efficient coarse and pre-grinding of suspensions in a high flow recirculation process.

The initial particle size for some products in applications contain coarse crystalline particles, or are agglomerated to particle up to the mm range. Most pre-dispersion processes are not able to comminute these particles to the required size, to receive either the final quality or to allow the subsequent fine grinding process step.

ProPhi provides particle size distributions that allow the final fine grinding step using smallest grinding media and thus significantly reducing the total energy requirement for the preparation of such products.
