Mixing, Dispersing, Kneading and De-aeration
Mixing is one of the basic operations in mechanical processing engineering. In this way, at least two starting substances are combined into one substance that should be as homogeneous as possible.
The mixing process is commonly followed by de-aeration since, during the processing of liquid to highly-viscous products, pockets of air or gas often cause problems. Pockets of air, hence oxygen, can have negative effects on the product – such as oxidation, rancidity of fats or oils, discoloration or deterioration of aroma and taste for example – and, for materials that are to be coated, can lead to porous and pitted surfaces. In contrast, de-aerated products are usually more chemically stabile and more durable.

For processing large batches of moderate- to high-viscosity product, the PMD and PMD-VC intensive mixers are the machines of choice. The stationary mixing and dispersing units are successfully utilized primarily in the paint, printing ink and pigment industries.
The NETZSCH MasterMix® dissolvers are fast, high-powered dispersing units for simple mixing tasks. They can easily process products with viscosities up to 100 Pa·s from a broad range of applications.
The NETZSCH planetary mixing and kneading machines show their true magnitude with difficult-to-disperse products and high viscosities. In particular, dispersion of finely-powdered and lightweight components in liquids is accomplished extremely quickly with product-specific mixing elements such as crossbeam and butterfly agitators or various dispersion disks.
Compact enough to be included at virtually any point in your process. The self-pumping portable unit features rotor/stator based technology with multiple stator configurations available.
Featuring a precision high-speed rotor, which creates a vigorous pumping action as it draws liquid into the stator inlet. Liquid is discharged at high velocity through machined slots in the stator.
Portable Stand Mount for various mixing applications, accepts high-speed to low-speed variable speed mixers and dispersers.
The NETZSCH vacuum de-aerator offers a simple way to remove even micronized gas and air pockets from liquids of various viscosities or from viscous compounds and pastes.
