Background

The coarse aggregate refers to that in concrete, sand and stone play a role of a skeleton and are called aggregate or aggregate, wherein the aggregate with the particle size of more than 5mm is called the coarse aggregate. The common coarse aggregate of common concrete includes broken stone and pebble. The broken stone is made of natural rock, pebble or mine waste rock through mechanical crushing and screening, and the particle size of the broken stone is larger than 5 mm. Pebbles are rock particles with a particle size of more than 5mm, which are formed by natural weathering, water flow transportation, sorting and stacking. The needle-shaped particles are the cobble and broken stone particles with the length 2.4 times larger than the average particle diameter of the corresponding grade of the particles; the particles having a thickness of less than 0.4 times the average particle diameter are flaky particles (the average particle diameter means the average of the upper and lower limit particle diameters of the fraction). The thick aggregate can often be used when water conservancy construction, can use screening installation to filter before using, but the screen cloth aperture of current screening installation all is fixed, when the thick aggregate of different particle diameters is filtered to needs, need change the screen cloth just can, but the change of screen cloth is more loaded down with trivial details, needs the longer time, can influence the efficiency of work like this, and we propose the water conservancy construction that an aperture was adjusted and use thick aggregate sieve for solving above-mentioned problem for this reason.
