Grinding System Zeta®

The Grinding System for Circulation and Multi-Pass Operation

Suitable for a wide variety of 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. During operation, 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 tank.

The forced conveyance of the product through the grindintensive grinding media fill guarantees a uniform load inside the mill, while the dynamic separation system reliably retains the grinding media in the grinding zone. This enables extremely high throughput rates without pressure build-up in the grinding chamber and creates ideal conditions for circulation or multipass operation. For precise temperature control, the agitator mill is equipped with an optimized cooling system. A coolable agitator shaft is also available as an option.

Versatility without Limits

The NETZSCH Zeta® grinding system has a wide range of applications and is equally suited both for processing very low-viscosity products and grinding products with a high solids concentration and correspondingly high viscosity, and everything in between. The product-wetted components are available in various materials. Depending on the application, materials such as NElast, ceramic, abrasion-resistant special steels and stainless steel are available.
