NOBILTA

SUPER HIGH SHEAR MIXER

The Nobilta super high shear mixer is a multifunctional processing device for high speed, precision, powder mixing, particle surface modification and shape enhancement. It combines particles into composite materials by applying mechanical force in a dry process, without using a binder.

The Nobilta is suitable for processing powders from nano to micron size, particle design and particle treatment in the nano range. It offers a compact design and high energy-efficiency.

Working principle

Mixing / dispersion typically requires the three mechanisms of convection, shear and diffusion. But for composing nanoparticles, an additional strong, mill-like mechanism (impact, compression, attrition) is required to overcome the strong agglomeration force of the nanoparticles. Typical mixers are biased towards one of the three mixing mechanisms, requiring additional equipment. The Nobilta however, combines mixing, composing, surface treatment and spheronization in one piece of equipment.

The Nobilta consists of a horizontal cylindrical vessel with a specially designed rotor rotating at a high speed of 30 m/s. The rotor configuration has been designed to exert impact, compression, and shear forces on each individual particle equally. Adjusting the rotor speed and run time controls the amount of processing (mixing, surface treatment) to the nanoparticles. The vessel is jacketed to prevent heat build-up when processing heat-sensitive materials at high energy levels, preventing sticking and degradation.

  • Composing
    Nano-scaled particles are permanently fused onto the surface of micron-scaled particles without binders, combining material properties of different particles into one particle to enhance chemical reaction, flowability, heat resistance, electric performance, and solubility.
  • Precision mixing (Dispersion)
    Enabling distributive and dispersive mixing in one apparatus to improve colour, tone, reactivity, calcination ability and mechanical intensity.
  • Shape enhancement (Spheronization)
    Improving round shape and reducing BET surface area for enhanced flowability and packing density.

  • Systems

    Hosokawa Micron has been developing innovative processing equipment and systems for a wide variety of products and markets for more than a century. As a result, we can draw on an unparalleled amount of know-how when designing new powder mixing systems.

    In a powder mixing system, the equipment, process steps and interacting parameters must all work together as an integral solution in order to ensure the optimal functionality, quality and efficiency of your total system. That's why we carefully select, configure and integrate all the components and processes when designing a powder mixing system.
