[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. When preparing recycled concrete, the discarded concrete must first be crushed into particles, so special concrete recycling equipment is required for processing. Concrete in construction waste can also be recycled and reused. Construction waste usually contains recyclable metal substances. If these metal substances are not separated, it will not only cause waste of resources but also affect the quality of recycled concrete.

The metal substances fall on the second guide plate and enter into the second box for collection. However, when too much concrete is put in at one time, the metal substances away from the rotating drum will be blocked by the concrete and difficult to be adsorbed by the magnet, resulting in poor recovery effect of the metal substances in the concrete, which has certain limitations.
