  • Screening and Classification

    DSM screens (or sieve bends) are a fixed screen commonly used for dewatering. They are a fine screen and are able to process particles sized down to 500um due to their shape. The screen is fed from the top with slurry where the slope is practically vertical, while the deck changes in an elliptical fashion such the discharge is almost horizontal.

  • Classification of Sand The Construction Civil

    The sand is classified according to the size of grains, the sand are classified as fine, coarse and gravelly. The sand which is passing through a screen with clear openings of 1.5875 mm is known as the fine sand. It is mainly used for plastering jobs.
