Description

A device for manufacturing a sand using a construction waste matter

The present invention relates to a wet regeneration crushed sand manufacturing apparatus using construction waste, in particular to remove the soil and foreign matter contained in the input construction waste in advance to produce a high quality crushed sand and reduce the load of the crusher The present invention relates to a wet regeneration crushing sand manufacturing apparatus that can increase the yield.

An example of an aggregate processing apparatus is shown in Korean Utility Model Registration No. 4300 of 2002, and a process diagram thereof is shown in FIG. This processing equipment is equipped with a first hopper to which high-quality aggregates are injected, a second hopper to which aggregates already processed through recycled aggregates, and a third hopper to which construction wastes collected from various construction sites are put. .

The recycled aggregate or high-quality aggregate put into the first hopper is fed to the first vibrating separator, which is a sorting means for separating the aggregates by the size of the aggregate through the first charity which discharges the metals contained in the aggregate. After being returned and crushed, it is fed back to the first vibrating separator.

Aggregates of 5 to 25 mm passing through the first vibrating separator are discharged to recycled aggregates, and fine aggregates of 5 mm or less are introduced to the classifier together with water introduced from the water tank.

Sand of 5 mm or less introduced into the classifier is discharged to the recycled aggregate. On one side of the classifier, a cyclone sump is installed to reduce the throughput of the classifier when there is a large amount of water and sand put into the classifier, and sand and water introduced into the cyclone sump are re-introduced into the classifier. Only sand is discharged.

In addition, in order to reduce the amount of sludge generated from the floater or foreign matter discharged from the classifier, the water discharged while being compressed with water is transferred to the water tank, and the compressed sludge from the filter press is transferred to the sludge silo and discharged to the outside. To be.

Recycled aggregate, etc., put into the second hopper is transferred to the first vibrating screen so that aggregates of a predetermined size or more are conveyed to the cone crusher, and are put into the roll crusher where the surface of the aggregate is processed via the second vibrating screen.

Aggregate that has undergone a roll crusher is introduced into the impact crusher through a second charity, crushed, and then introduced into the first vibrating separator.

The construction waste put into the third hopper is put into the jaw crusher which is crushed to a certain size through the vibrating feeder and then into the third vibrating screen. Aggregate added to the third vibrating screen is put into the crusher together with the aggregate conveyed from the first vibrating screen and is subjected to the re-crushing process, thus repeating a series of processes introduced to the first vibrating screen again.

The processing device as described above has the advantage that it is possible to simultaneously process the construction waste and the recycled aggregate already processed through one device, but the construction waste injected into the hopper 3 is directly put into the jaw crusher and the fine particles such as dust By crushing together, the production efficiency of aggregate is reduced.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wet regeneration crushing sand production apparatus using construction wastes whose structure is improved to increase the production efficiency of crushing sand.

It is another object of the present invention to provide a wet regeneration crushing sand production apparatus using construction waste to reduce the load of the crusher by bypassing the crushed matter of a certain size to increase the production.

Another object of the present invention is to provide a wet regeneration crushing sand production apparatus using the construction wastes improved to improve the sorting efficiency of the vibration screen for sorting the crushed material according to the size.
