Proven Excellence. Agitator Bead Mill Alpha® The next Generation of Agitator Bead Mills CHEMICAL INDUSTRY a Business Field of NETZSCH Grinding & Dispersing

NETZSCH Alpha® The next Generation of Agitator Bead Mills Agitator bead mills are grinding machines for ultra-fine processing of solids in liquids. Their area of application covers the particle size range from 200 µm (max. 500 µm) down to the submicron (nanometer) range. With a comminution factor down to 1 : 10 000 (200 µm  20 nm), the application range is extensive and the variety of tasks extremely diverse. The wetting and homogenization of solids in liquids, deagglomeration and dispersion, all the way to true comminution of primary particles make the agitator bead mill a universal wet...

Fresh creative standards were also set for the new Alpha® from the very beginning and a new expression of form was used that distinctly communicates the innovative strength of NETZSCH in the design as well. In place of the cast housing, external instruments and pipework there is a clear, dynamically-curved welded construction of heavy plating which also fulfills a load-bearing function. The ergonomic design of the machine stand was a primary consideration during the development phase. The Alpha® has a self-supporting grinding chamber, which ensures good accessibility to the grinding area...

NETZSCH Alpha® Modular Machine Platform for Customized Solutions The new Alpha® sets the standard when it comes to flexibility and handling and, thanks to its modularity, allows customer-specific solutions: different grinding systems can be mounted on one base stand – customized for the requirements of the product you need to process. The advantage this modular system brings you is cross-system standardization and thus the option to economically convert a machine to a new grinding system. In addition, the Alpha® is also the platform for future NETZSCH technologies, which guarantees you...

Focus on Your Benefits Common platform for three grinding systems allows easy conversion to the respective optimal process conditions Long-term investment security, since the Alpha® is also the platform for future NETZSCH technologies Self-supporting grinding chamber for optimum accessibility to the grinding area during maintenance All supply lines feed into the machine from the top, which prevents obstructions at ground level Optimal accessibility to the parts in the machine stand that must be maintained Spatial separation of rotating machinery and media-carrying fittings ensures a high...

The NETZSCH Alpha® Discus system is the quantum leap in disk grinding technology. The further optimized Discus disk agitator combined with the NETZSCH DCC® separation system guarantees you extremely high throughput rates with significantly narrower dwell time distributions and therefore more intensive grinding with uniform impact intensity. The power input of the mill increases considerably, with a simultaneous increase in energy efficiency. The Discus grinding system activates and optimizes the movement of the grinding beads between the disks, which leads to a higher power input and a...

Continuous agitator bead mills with horizontal disk agitator With the Discus grinding system, the movement of the grinding media between the disks is activated and optimized. This leads to a high power input and a grinding efficiency with low specific energy consumption The product flows axially from the inlet through the grinding chamber and is stressed by the shearing, pressure and impact action of the grinding beads and thus ground or finely dispersed A highly effective centrifugal separation system allows the product to flow out, while the grinding beads are retained in the mill Discus...

NETZSCH Alpha® Discus System Highest Efficiency with Low Energy Consumption The Further Optimized Model DCC® Pre-Classifying Separation System The highly-efficient, dynamic centrifugal separation system makes it possible to use grinding media of various densities, matched to the task at hand. In addition, grinding beads as small as 0.2 mm in diameter can be used with this system. The separation system ensures that even with high viscosities the mill can be operated far below the critical point of grinding media compression. This means you maintain extremely stable operational performance,...

Material Options for any Product In order to meet the requirements of the widest range of products and to guarantee product compatibility, we offer a variety of grinding chamber materials. Matching the grinding chamber material to the product properties facilitates low-wear operation of the mill. The use of a low-contamination grinding chamber design leads to an enormous expansion of the possible product applications for the machine. Selection of Grinding Chamber Materials ■ Highly wear-resistant special steel ■ Stainless steel ■ NETZSCH-Ceram Z ■ NETZSCH-Ceram N ■ NETZSCH-Ceram C ■ NElast...

Suitable for every viscosity and almost any product, with this technology you will achieve the highest product qualities and finenesses into the nanometer range using a wide variety of grinding media from 0.1 mm to 3 mm in diameter. The closed horizontal agitator bead mill is designed for the highest product throughput rates and has a peg grinding system with extremely high grinding intensity.

Easy and Reliable Operation The Zeta® grinding system is, in every respect, a user friendly, low-maintenance and very reliable grinding system. Starting with the structural design of the agitator mill, there is already a number of advantages: the horizontal orientation guarantees a homogeneous fill of the grinding media in the grinding tank. The start-up performance of the mill with product is therefore unproblematic and very high flow rates can be set without pressure build-up. The product outlet is located directly on the bottom of the grinding tank and is therefore easily accessible....
