Self-Controlled Cone Crusher with Cascade and Distributor}

The present invention relates to an automatically controlled con crusher in which a cascade and a distributor are installed, and more particularly, by automatically adjusting the spacing of the crushing space between the mantle and the concave and the rotational speed of the driving unit in consideration of the amount or properties of the aggregate. It is about an automatically controlled conclave equipped with a cascade and a distributor that can produce high-quality recycled aggregate under optimal operating conditions.

Construction waste generated in the process of dismantling or redeveloping old bridges, roads, and various buildings is generally recycled as recycled aggregate for the protection of the natural environment and recycling of resources.

In general, the intermediate treatment of construction waste includes a crushing process of crushing into an aggregate size for recycling using a plurality of crushers having crushing capacity of various specifications, and a separation of sorting and separating reinforcing bars or foreign substances from construction waste that has undergone the crushing process. It is made up of a series of successive processes, such as processes.
