Planetary Micro Mill PULVERISETTE 7 premium line. This arrangement increases the maximum rotational speed in the premium line to 1100 rpm, enabling a 150% increase in the kinetic energy of the grinding bodies. The comminution of nanoparticles for certain materials can be achieved because of a major reduction in the nanoscale grinding time.

Zinc oxide nanoparticles were synthesized by K Vojisavljevic et al[121] by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The deviation of the lattice parameters from single crystal values was related to defect creation and increase of strain inside the hexagonal lattice of milled ZnO nanoparticles.

Wet type microbead mill for grinding and nanoparticle dispersion, especially for dispersing nanoparticles with low crystal damage. Overview. Dual Apex Mill (DAM) is a dual-axial wet type bead mill equipped with a centrifugal bead separator and an agitating rotor, which are driven independently, with a high flexibility in the agitating rotor revolution.

DYNO ® -MILL NPM. The patented DYNO ® ACCELERATOR initiates the powerful, hydraulic motion of the grinding beads and guarantees a high and constant energy input for low-viscosity products. Dynamic grinding bead separation system for an optimal process when ultra-fine grinding beads with diameters from 0.05 to 0.2 mm are used.

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application.
