Based on a century of experience RETSCH develops size reduction and sieving equipment which is characterized by excellent performance, operating convenience, safety and a long lifetime.
How are nano particles produced? The “Bottom-Up” method synthesizes particles from atoms or molecules. The “Top-Down” method involves reducing the size of larger particles to nanoscale, for example with laboratory mills. Nano particles are produced by colloidal grinding which involves dispersion of the particles in liquid to neutralize the surface charges. Factors such as energy input and size reduction principle make ball mills the best choice for the production of nanoparticles.
