Description

Technical Field

[0001] This utility model relates to the field of recycled concrete technology, specifically to a device for secondary crushing and refining of coarse aggregates in recycled concrete. Background Technology

[0002] Aggregates, also known as aggregates, are divided into coarse aggregates and fine aggregates. They are one of the main components of concrete. They primarily function as a skeleton and reduce volume changes caused by the drying shrinkage and wet expansion of cementitious materials during setting and hardening. They also serve as inexpensive fillers for cementitious materials. Aggregates are classified as natural or artificial. Natural aggregates include crushed stone, pebbles, pumice, and natural sand; artificial aggregates include cinder, slag, ceramsite, and expanded perlite. Aggregates with an apparent density of less than 1700 kg / m³ are called lightweight aggregates and are used to manufacture ordinary concrete. Particularly heavy aggregates are used to manufacture heavy concrete, such as radiation-shielding concrete. When utilizing coarse aggregates, they need to be refined; therefore, a secondary crushing and refining device for recycled concrete coarse aggregates is required.

[0003] However, existing crushing and refining devices have weak refining functions. During use, they are difficult to crush and further refine the coarse aggregates that have been refined in batches. This results in incomplete refining of the coarse aggregates by a single refining process, affecting the refining effect. Moreover, existing crushing and refining devices have poor filtration effects. After refining, they are difficult to filter the refined coarse aggregates, resulting in a small amount of incompletely refined coarse aggregates mixed in, which affects subsequent use.
