4 The Efficient Grinding System Functionality and efficiency The ZETA grinding system represents the evolutionary development of the John system in combination with the rotor-slotted pipe separation system. The enclosed horizontal agitator bead mill is designed for the highest product throughput rates and is equipped with a pin grinding system to provide the highest grinding intensity. The product flows horizontally through the agitator mill from the inlet on the bearing side and is discharged through the slotted pipe at the bottom of the tank. The compelled flow of the product through the media-intensive grinding zone ensures uniform exposure within the mill. The dynamic separation system reliably contains the grinding media in the grinding zone. This allows the highest possible throughput rates without pressure build-up 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 multi-zone cooling system. In the standard model, the grinding tank, agitator shaft and product outlet can be cooled to prevent overheating of the product. Optionally, the slotted section of the agitator shaft can be cooled as well. Complete flow around the slotted section of the agitator shaft not only increases the cooling surface, but the heat transfer efficiency as well. Grinding chamber models in different materials and new control concepts expand the application possibilities. Sectional view of the ZETA grinding system Your advantage is our focus Pin grinding system for highest grinding intensity Finenesses down to the nano range Very narrow particle size distribution Highest efficiency Exact reproducibility Efficient centrifugal separation system Use of extremely small grinding beads from 90 μm Specifically designed for maximum throughput rates Ideal for circulation or multipass operation Optimal energy input with efficient cooling Multi-zone cooling system for ideal temperature control 4

5 Unlimited versatility The high-speed ZETA circulation system is a grinding system with many different applications. It is equally suitable for processing products with very low viscosity and grinding products with a high concentration of solids and a correspondingly high viscosity. NETZSCH-BEADS are grinding media ideally tailored to the ZETA grinding system and are available in various materials and sizes ranging from 0.09 mm to 3 mm diameter. The product-wetted components of the grinding system can be made of different materials. Depending on the application, materials such as NElast, ceramic, wear-resistant special steels and stainless steel are available. A pharmaceutical version of the grinding system is also available. The targeted multi-zone cooling system allows processing of products at very low temperatures. Standard design - optionally available in highly wear-resistant special steel for processing products containing solvents or in stainless steel for waterbased products. Ceramic design - for iron-free grinding of abrasive, contaminationsensitive, solvent-based products. The product-wetted grinding chamber components are available in a choice of NETZSCH-CERAM Z, NETZSCH-CERAM N and NETZSCH-CERAM C. NElast design - all product-wetted parts are coated with NElast for ironfree processing of contaminationsensitive, water-based products Your advantage is our focus Pharmaceutical design - the DELTAVITA series in a polished, dead-space-free design is easy to clean and sterilize. Universally applicable for every product Can be scaled up from laboratory machine to production machine Reliable use of a wide variety of grinding media from 0.09 mm to 3 mm NETZSCH-BEADS, in particular the ZETABEADS and ZETABEADS PLUS, are grinding media ideally tailored for the high-speed LMZ ZETA grinding system Achieve the best product quality with increased output and improved energy efficiency Additional product-optimized grinding chamber configurations available upon request 5

6 Operational Reliability and Convenience Easy, dependable operation The ZETA grinding system is in every regard a very user-friendly, lowmaintenance and extremely reliable grinding system. The many advantages start with the structural design of the agitator mill: The horizontal orientation guarantees uniform filling of the grinding media into the grinding tank. Start-up of the mill with product is therefore unproblematic. The highest flow rates can be set without pressure build-up. The double-acting cassette-type mechanical seal is mounted in the reduced-flow area of the grinding chamber, so the mechanical load from grinding media is minimal. The product outlet is directly at the bottom of the grinding tank and is therefore easily accessible. The maintenance-free slotted pipe inside the grinding chamber prevents loss of grinding media when the machine is idle. During operation, the grinding media are kept away from the slotted pipe by the rotor of the separator system, thus preventing flow-induced bead compression and blockage. A displacement element 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 discharge temperature of the product after it passes through the intensive grinding zone but while it is still inside the agitator bead mill. Cleaning made easy The optimized cleaning concept with a wash cycle system allows practically residue-free cleaning of the agitator LMZ 25 high-speed mill with NETZSCH-CERAM Z grinding chamber bead mill with minimal cleaning agent, all without emptying the grinding chamber. Your advantage is our focus Horizontal design facilitates maintenance Homogenous grinding media distribution in the entire grinding chamber No grinding media compression Double-acting cassette-type mechanical seal in the reducedflow area of the grinding chamber Easily accessible separation system Maintenance-free slotted pipe Easy, practically residue-free cleaning Adjustable-speed wash cycle systems 6

7 Ergonomic design The machine stand for the ZETA series is of one-piece construction and is therefore very stabile and practically vibration-free. The feed pump can be mounted directly on the machine stand, shortening distance between the pump and the grinding chamber and thus minimizing product loss. If the grinding chamber is 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 Feed pump 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 for loss-free exchange of grinding media Coolable rotor 7
