Generally, recycled aggregate is also referred to as recycled aggregate, and refers to aggregate manufactured so that construction waste or waste concrete can be crushed and selected for reuse.

In addition, a large amount of washing water generated in the production process of the recycled aggregate is required. If a large amount of the washing water generated in such a manner is caused to flow, the used washing water must be recycled.

Since the used washing water contains various foreign substances, it is necessary to remove various foreign substances contained in the used washing water, so that it can be recycled as washing water again, but it has been difficult to remove the foreign substances.

Since the foreign substances contained in the used washing water are generated mostly as floating matters, the present applicant has proposed a floating material removing device using centrifugal force. In the floating material removing device using centrifugal force, the floating material contained in the washing water used while rotating by centrifugal force, It was a method to remove it after allowing it to float.

In order to reduce the volume of soil particles contained in water, a compression process is performed. At this time, in order to smooth the compression, an aggregate is used to effectively carry out the compression process, and inorganic sludge is generated.
