Gravel scribing to remove foreign matter by rubbing the aggregate

The present invention relates to a gravel scrib that removes foreign substances by rubbing aggregate, and more particularly, to recycle construction waste as recycled aggregate, or to remove foreign substances mixed in the process of manufacturing crushed stone aggregate and sand and earth dust buried in aggregate It relates to a gravel scrib that removes foreign substances by rubbing aggregate raw materials for the purpose of removing them, and rubbing the input raw materials together to separate and separate sand, earth dust, and foreign substances.

Recently, a large amount of various construction waste has been generated due to the redevelopment of houses and apartments and the repair of roads, etc., and the concrete mix that requires high strength at the construction site must be a clean aggregate without foreign substances and soil particles.

Although waste concrete and raw stone are crushed and recycled as recycled aggregates or fine recycled aggregates, the amount of recycled aggregates is less than that of processing due to quality problems, so a lot of crushed aggregates are accumulated. The high quality of concrete mixed ready-mixed concrete products is required by removing soil powder from aggregates produced at forest aggregate sites or selective crushing sites and removing foreign substances.

There are very few sites with effective treatment facilities for this.

Aggregate containing soil powder and foreign substances adversely affects the ready-mixed concrete product, which causes poor construction, causes environmental pollution, and lowers the quality of the ready-mixed concrete product. The removal of soil dust and foreign substances from aggregates is essential, and active improvement of the quality of aggregates is being emphasized.

Recycled aggregates and crushed stone aggregates contain a lot of fine powder, earth dust, cement waste yeast, foreign substances, etc., or because of irregular grain size, the overall quality of recycled aggregates decreases, and products that do not conform to the recycled aggregate quality regulations are produced. It acted as an important factor impeding technological development as the profitability of construction waste companies, which were avoided and found an appropriate way out, and which required huge facilities and costs, did not improve their profitability.

When producing recycled coarse aggregate by crushing conventional construction waste or manufacturing crushed stone coarse aggregate, coarse aggregate raw materials are injected while spraying water for the purpose of removing soil dust and foreign substances, and the spatula-shaped wings rub the aggregate and transport the aggregate. In the process of rubbing sand, soil powder and foreign substances adhering to coarse aggregates to separation, washing and separation, or in the process of manufacturing recycled fine aggregate or artificial sand, in the process of crushing and grinding or water washing, the cleaning effect of the aggregate is not good. Removal is not good.

However, due to the defect that the wear plate wears easily during collision with the aggregate and needs to be replaced frequently, the maintenance and replacement cycle is shortened, making it difficult to manage, and it is impossible to provide aggregate of uniform quality.
