[0002] The diameter of fine aggregate particles is between 0.16 and 5 mm. Natural sand is generally used, such as river sand, sea sand and valley sand. When natural sand is lacking, artificial sand ground from hard rocks can also be used. The diameter of coarse aggregate particles is greater than 5 mm. Commonly used ones are crushed stone and pebbles. Under the same conditions, the strength of crushed stone concrete is higher than that of pebble concrete.

In addition, after the existing fine aggregate feeding dust reduction and dust removal device adopts spraying to reduce dust, it is not convenient to recycle the sprayed water source, which easily causes waste of water resources. For this reason, we propose a fine aggregate feeding dust reduction and dust removal device. Utility Model Content
