Method of diatomite concentration and activation

The method is as follows. Preparation of diatomite consists in grinding and zatvorenii water dispersant. The suspension obtained is fed to the separating device, for example, liner, hydrocyclone, centrifuge, and other centrifugal or vibration forces allows you to select target fraction with a minimum content of sand and clay impurities.

Investigation of particle characteristics and enhancing ...

The grinding procedure ensured effective particle size reduction and produced an ultrafine diatomite (D 50 below 10 μm) with low energy consumption. The decline in particle size caused an increase in the specific surface area (SSA) of diatomite without significantly changing pore volume and size.
