For the use of Micro Grinding Beads CHEMICAL INDUSTRY a Business Field of NETZSCH Grinding & Dispersing

Zeta® RS High-performance Mill The future begins today The demand for materials with particle sizes in the range far below 1 µm is steadily growing. This is due to the functionoriented benefits that these materials bring to the finished product. In the colloidal particle size range, it is important to distinguish between true comminution, dsagglomeration and disaggregation. While with true comminution of coarse primary particles, compression and impact loads must be transferred to them, these direct loads often damage them during dispersion of agglomerated nanoscale primary particles that are...

During development of the Zeta® RS machine series, special emphasis was placed on ease of use. Filling and emptying as well as servicing and cleaning the machine are easily accomplished without the loss of grinding media. Positionable grinding tank Integrated, removable grinding media collection tray For even greater usability, an optional swivel-mounted grinding chamber is available for models Alpha® Lab Zeta® RS to Zeta® RS 10 Filling Position Operating Position

Grinding System & Mode of Operation Grinding System The Zeta® RS series agitator bead mills were developed for the use of so-called micro grinding beads (30 µm - 300 µm). This was achieved through the adaptation of the geometric dimensions of the NETZSCH System Zeta® circulation mill and the use of innovative separation systems. Peg grinding system with small length/diameter ratio and high power density Highly effective centrifugal separation systems The grinding media retention systems can be selected according to the product requirements Mode of Operation With the Zeta® RS agitator bead mills,...

Separation Systems, Convertibility & Ma Separation Systems High throughput rates in circulation operation and the use of micro grinding media in the range of 30 µm 300 µm are necessary for dispersion and true comminution into the nanometer range and place special demands on the grinding media retention system. The advanced centrifugal separation system can be constructed either as a rotating screen or, in a patented ODC (Open Dynamic Classifier) or SDC (Separately Driven Open Dynamic Classifier) version, it can be screen-free. The Zeta® RS can be operated with an ODC (Open Dynamic Classifier)...

Convertibility For the preparation of smaller product quantities, a special conversion kit was developed that facilitates very quick conversion of the Zeta® RS 4, with a grinding chamber volume of 4 l, to the grinding chamber of the smaller Zeta® RS 2, with a volume of 2 l. Two easy-to-install adapter rings guarantee accommodation of the smaller-diameter grinding tank and the agitator shaft. Grinding Chamber Materials The Zeta® RS series machines are available in various wear- and corrosion-resistant materials in proven NETZSCH quality for metal-free fine grinding. ■ NETZSCH-Ceram Z, NETZSCH-Ceram...

■ Compact design for minimum space requirement ■ Easy handling with swiveling grinding unit and sliding grinding tank ■ Prevention of grinding media loss, very easy cleaning and ease of use ■ Reliable use of micro grinding beads in the range of 30 pm - 300 pm ■ No screen blockage thanks to the ODC/SDC separation system ■ Variety of materials available for grinding systems (can be interchanged) ■ Large selection of grinding chamber materials (can be combined) Zeta® RS with SDC System

With the new Alpha® Lab laboratory agitator bead mill, the concept of the new generation of agitator bead mills, first introduced in 2015 with the Alpha® platform, has been systematically carried over to the laboratory mill. During redesign of the machine stand, special attention was given to ease of use and ergonomics. The grinding chamber of the Alpha® Lab Zeta® RS is swivel-mounted so that filling with grinding media, emptying the grinding system with minimal hold-up and discharging the grinding media after the run all involve the least possible effort. In addition, different grinding systems...

Unlimited Flexibility The possible variations of the multifunctional Alpha® Lab Zeta® RS laboratory mill offer yet another feature. In addition to the different scale-up-capable grinding systems in a variety of material options, the machine can also be converted to the smaller grinding chamber designs of the MiniSeries with a 230 ml capacity and the MicroSeries with a 110 ml capacity. A special conversion kit that facilitates short installation times was developed for this purpose. L abStar conversion kit on the MicroSerie L abStar conversion kit on the MiniSerie

The control system of the Zeta® RS high-performance mill facilitates efficient and automatic process control. Acquisition of the energy input, temperature and pressure along with the existing safety functions, enables automatic operation by which preselected parameters start up automatically. NETZSCH GRAPH offers various control strategies, the measured values are graphically assigned to the test points on the display, each formula can be processed automatically according to individual parameters. In addition, we offer integration into higher-level control systems as well as data acquisition...

Data Acquisition The data acquisition system serves to record the values measured by a machine and comprises the hardware required to transfer the existing measurements via an Ethernet connection and the software for installation on a PC. The measured and input data are stored in a CSV file and the current measured values are displayed. The acquisition rate can be pre-set by the operator to intervals ranging from 1 s to 10 min. After successful data acquisition, further evaluation is possible in a spreadsheet program. Your Benefits ■ High operational reliability ■ Various control methods ■ Quality...
