Synthesis of Highly Active Nanozeolites Using Methods of ...
Abstract Methods for preparing zeolites with the particle size of 50–200 nm using mechanical milling on bead mills (top-down approach) are analyzed. The milling can be described by a first-order rate equation, but mathematical models allowing prediction of the particle size and degree of crystallinity of zeolite after milling, based on the process …

This implies that smaller MNA particle size could be achieved at shorter milling time. The average particle size for 3, 5 and 7 h was obtained in the range of 10 to 22 nm. As the milling time increases, the micro-strain in the sample also increases . Hence, prolonged milling hours will produce more strain to the samples.

Particle Size Distribution of Settled Dust
Particle size determinations were made with both the coulter counter and the Bahco micro-particle classifier. The two methods yielded comparable results. It was found that set-tled dust particles for all practical considerations were all greater than SO microns in equiv-alent diameter. Regulations based on these findings are being developed.
