Grit screening plant for construction

Technical Field

The utility model relates to a grit field, in particular to grit screening plant for construction.

Background

Sand, which refers to a loose mixture of sand and gravel. Geologically, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size greater than 2mm are called gravel or cobble (the difference is that the particles are rounded to different degrees, and the terms conglomerate and sandstone can be seen in detail). If the crushed stones in the sand are mostly gravel, the sand is called sand gravel. Sandstone is also known as sand in daily life. Different sandstone structures have larger difference, and some sandstone structures have uniform particle thickness and different sizes; some gravels have good grinding roundness of the fragments and some gravels have sharp edges and corners of the fragments. Sand is a loose material, but its particles are generally hard and chemically stable in the surface environment.
