Description

Sand screening machine for constructional engineering

Technical Field

The utility model relates to the technical field of constructional engineering, in particular to a sand screening machine for constructional engineering.

Background

Sand, the name of the substance, or sand, is one of the particulate substances, sand is naturally occurring and is divided into very fine rocks, and the thickness of the sand refers to the average thickness of sand grains with different grain sizes mixed together. There are generally coarse, medium and fine sand fractions. The grain size distribution of sand refers to the proportion of sand size particles. If the sand is the sand with the same thickness, the gap is the largest, the sand with two particle sizes is matched, the gap is reduced, and the sand with three particle sizes is matched, so that the gap is smaller. Thus, the void ratio of the sand depends on the collocation degree of the particle sizes of the sand material. The graded sand not only can save cement, but also can improve the compactness and strength of concrete and mortar. The thickness of the sand is expressed as a fineness modulus Mx. The larger the fineness modulus, the coarser the sand. According to the fineness modulus size range, the sand is divided into coarse sand, medium sand, fine sand and extra fine sand.
