Soil Texture: Sand, Silt and Clay

Nov 30, 2016Coarse sand = diameter 2-0.2mm Fine sand = diameter 0.2-0.02mm Silt = diameter 0.02-0.002mm Clay = diameter less than 0.002mm. Note how the clay particles are much smaller than the sand particles – this is important as it means the total surface area of a clay soil is much greater and so the capacity to hold water is also much greater.

Die Casting Vs. Sand Casting

Oct 20, 2015Die casting can also produce features that cannot be made in sand casting, reducing the secondary costs over sand. If your company is a high-volume producer of products with a long service life (casting runs of 1,000 or more), the die casting process is most likely going to be the right choice over sand

Glass Beads Vs. Sand Blasting

Sand blasting is achieved by blasting sand on to a metal surface through very high air pressure. Sand blasting is a much quicker process but is also harsher on the underlying metal material. While glass bead blasting does not compromise the metal, sand blasting, similar to sand paper, has the capability of shaping and smoothing the underlying
