4 The powerful grinding system Functionality and efficiency The ZETA grinding system represents continued development of the John system combined with the rotor-slotted pipe separation system. The enclosed horizontal agitator bead mill is designed for the highest product throughput and is equipped with a high-intensity pin grinding system. The product flows horizontally through the agitator mill from the inlet on the bearing side and exits via the slotted pipe at the bottom of the chamber. The guided flow of the product through the media intensive grinding zone ensures uniform loading within the mill. The dynamic separation system reliably holds the grinding media inside the grinding zone. This enables the highest throughput rates without the build-up of pressure in the grinding chamber and creates the ideal conditions for circulation or multi-pass operation. For precise temperature control, the agitator mill is equipped with a multiplezone cooling system. In the standard model, the grinding chamber, solid shaft and product outlet can be cooled to prevent product overheating. As an option, the slotted section of the agitator shaft can be cooled as well. Complete flow around the slotted shaft not only increases the cooling surface area, but the efficiency of the heat transfer as well. Grinding chamber designs in various materials and new control concepts expand the range of applications. Sectional view of the ZETA grinding system Your advantage is our focus Pin grinding system with the highest grinding intensity Fineness into the nanometer range Very narrow particle size distribution Highest efficiency Exact reproducibility High efficient centrifugal separation system Use of grinding media as small as 90 µm Designed specifically for the highest throughput rates Ideal for circulation/multi-pass operation Optimal energy input with effective cooling Ideal temperature control through a multiple-zone cooling system 4

5 Unlimited versatility The ZETA high-speed circulation system is a grinding system that is equally appropriate for many applications ranging from processing very low-viscosity products to grinding products with a high solids concentration and correspondingly high viscosity. NETZSCH-BEADS are grinding media ideally suited for the ZETA grinding system and are available in a variety of materials and sizes ranging from 0.09 mm to 3 mm in diameter. The product-wetted parts of the grinding system can be supplied in different materials. Depending on the application, materials such as polyurethane (PU), ceramic, wear-resistant special steels and stainless steel are available. A pharmaceutical model of the grinding system is also available. The multiple-zone cooling system allows the processing of products at very low temperatures. Standard model - in highly wear-resistant special steel for the processing of solvent-based products. Ceramic model - for iron-free grinding of abrasive, contamination-sensitive solvent-based products. The productwetted grinding chamber components are available in zirconia, silicon nitrite and silicon carbide. Polyurethane model - all productwetted parts are PU-coated for ironfree processing of contamination-sensitive, water-based products. Pharmaceutical model - the DELTAVITA series in a polished, porosity-free stainless steel design with cleaning/sterilization unit. Your advantage is our focus Universally applicable for any product Can be scaled up from laboratory machine to production machine Safe and reliable use of a wide range of grinding media from 0.09 mm to 3 mm NETZSCH-BEADS grinding media, in particular the ZETABEADS and the ZETABEADS PLUS are ideally suited for the high performance ZETA grinding system Achieve optimal product qualities with better performance and improved energy efficiency Additional product-optimized grinding chamber configurations available upon request Exchangeable inner tank 5

6 Reliability and comfort Safe and reliable operation The ZETA grinding system is in every respect a very user-friendly, low-maintenance and reliable grinding system. The structural design of the agitator mill has a number of advantages: The horizontal orientation ensures homogeneous distribution of grinding media in the grinding chamber. Thus, start-up of the mill with product is unproblematic. The highest flow rates can be set without pressure build-up. The double-acting cartridge-type mechanical seal is mounted in the low-flow grinding chamber area. The mechanical load due to grinding media is minimal. The product outlet is located directly on the grinding chamber floor and therefore easily accessible. The maintenance-free slotted pipe within the grinding chamber prevents the discharge of grinding media when the machine is idle. During operation, the bead retention screen is kept clear of the grinding media by the rotor of the separation system, thus preventing bead compression and blockage. A displacement device in the slotted pipe increases the flow speed in the outlet area and, in conjunction with short pipelines, prevents product entrainment. Optional cooling of the displacement device lowers the temperature of the product inside the agitator bead mill. Cleaning made easy The optimized cleaning concept with circulation wash system allows nearly residue-free cleaning of the agitator LMZ 25 high-speed mill with zirconia grinding chamber design bead mill with minimal cleansing agent, all without emptying the grinding chamber. Your advantage is our focus Horizontal design simplifies maintenance Homogeneous distribution of grinding media throughout the grinding chamber No grinding bead compression Double-acting cartridge-type mechanical seal Easily accessible separation system Maintenance-free slotted pipe Easy, practically residue-free cleaning Adjustable-speed circulation washing systems 6

7 Ergonomic design The machine stand for the ZETA series is of one-piece construction and is therefore very stable and vibrationfree. The feed pump is mounted directly on the machine stand, shortening distance between the pump and the grinding chamber and thus minimizing product loss. When the grinding chamber must be opened for maintenance, the removal assembly provides an expedient mounting aid. Disassembly of the grinding chamber and tank bottom requires no additional lifting equipment. The integrated service cart holds the entire bead charge and prevents loss of grinding media during maintenance. Your advantage is our focus Ergonomic design Supply pump mounted on the machine stand LMZ 60 high-speed mill with tank removal assembly and bead collection cart Short pipelines Integrated tank removal assembly Bead collection cart prevents loss of grinding media Coolable rotor 7

8 Control and monitoring with no bounds You have the choice Whether you choose the standard version or integration into higher-level process control systems: an abundance of control options are available for the ZETA grinding system. Providing the capability for efficient process control with the aid of energy input detection, the standard version NETZSCH BASE already exceeds the required safety functions. The automatic screen-cleaning sequence allows trouble-free processing of the most challenging products. Starting with the NETZSCH TEXT control system, the mill runs automatically with pre-set operating parameters. NETZSCH GRAPH offers various control strategies, the measured values are graphically associated with the test points on the display, each formula can be automatically processed according to individual parameters. In addition, we offer integration into higher-level control systems as well as data acquisition hardware and software just discuss with our specialists.
