PARTICLE SIZE REDUCTION. Particle size reduction and control often proves itself as a critical step in industrial solids processing systems. Often times it is used as a method for enacting positive results downstream, such as increasing surface area for efficient thermal treatment or milling and homogenizing a material for consistent mixing
Now I am planning to reduce the particle size from micro to nanometer range as my UV-vis spectrometer operates for a particle size from 1nm to 100nm. ... a wet ball milling

Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and

Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

ranges from 35 to 115 percent of Nc. Where particle size reduction is quite critical, a variable speed drive is recommended. This permits the operator to control his mill speed to suit. Most mills rotate at 60 to 65 percent of critical speed (Nc). This formulation is for wet milling where as dry milling needs to be adjusted by 2 to 5 RPM faster

Sep 29, 2015 Air jet milling is found to be the most effective in reducing particle size from a d 90 of 37 m to 2.9 m compared to planetary ball milling (30.2 m) and single ball milling (10.5 m). XRD and TEM studies confirm that the planetary ball mill causes phase transformation to the less desired α-Alumina resulting in a notable decrease in surface area from 136.6 m 2 /g to 82.5 m 2 /g as measured
