Characteristics of Sand and Criteria for its Comminution
17 Jan 2013Sand is a very common unconsolidated sedimentary rock. Due to its physical and chemical characteristics sand is mainly used in the construction and glass industry. Therefore, the analytical evaluation of the chemical composition and aptness for its intended use makes the comminution of quartz sand a prerequisite. This application note discusses the use of Planetary Mills developed by FRITSCH and their suitability for the characterization of the particle size distribution.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.

Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
