Description

Technical Field

[0001] The utility model relates to the technical field of aggregate production, in particular to an aggregate pretreatment device for a mixing station. Background Art

[0002] Aggregate, also known as "aggregate", is a granular material that acts as a skeleton and filler in concrete and mortar. There are two types of aggregate: fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5 mm. Natural sand, such as river sand, sea sand and valley sand, is generally used. 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, but crushed stone is made by crushing rocks, and its cost is higher than that of pebbles. Commonly used coarse aggregates in lightweight aggregate concrete include natural porous rocks such as pumice, and artificial porous aggregates such as ceramsite and expanded slag.

[0003] The existing aggregate pretreatment device of the mixing station needs to crush and screen the aggregate step by step during use, and then crush and screen the unqualified aggregate again. It is impossible to perform this series of steps on the aggregate in an integrated manner, and it is also impossible to rinse and dry the crushed aggregate. Utility Model Content
