Description

Aggregate Continuous Crushing Mixer

The present invention relates to an aggregate crushing mixing device for producing pavement aggregate and vegetation earth and sand packaged in the order layer or road of waste sanitary landfill, more specifically, to aggregate aggregate continuously input through the aggregate mixing process And the wear efficiency of aggregates is high, and the replacement and repair work of the shredding blade which performs the shredding wear function at high speed rotation is easy, and the rotating centrifugal force is added to the shaft to significantly reduce the power consumption during operation. The present invention relates to an aggregate continuous crushing mixing apparatus for increasing the processing capacity by improving the granulation efficiency and mixing efficiency of aggregates.

In general, in order to prevent leachate from leaking at waste sanitary landfills or construction sites such as dams, reservoirs, and drainage channels, a water-repellent layer is installed. Since clay is difficult to purchase depending on the region, raw soil sand (granite soil), which is widely distributed in Korea among mixed order materials, is selected and used.

However, ground clay is not suitable for its own application, and it is used to make mixed materials including lime, cement, fly ash, bentonite, hardener, etc. in conventional ground soil. In general, a backhoe is used to mix raw materials using an excavator equipped with a bucket and a stabilizer, or, in some cases, a screw-type mixer or a cylindrical mixer. .

Conventionally, the mixing method of raw materials for ordering is not only the measurement of aggregates (soil, masato, sand, etc.) and water or emulsifiers, which are the main components of the mixed materials, but also the ratio of mixing is not constant and mostly depends on the snow mass. It is also the biggest factor of, and because the ground soil and mixed materials are installed in the order layer in a state where the different mixture materials are not sufficiently mixed, not only the compaction of the order layer is made firmly but also due to the imbalanced mixing of the mixed materials. There were problems of strength and downgrade.

That is, in the conventional method of mixing the raw materials for the order, the work is performed depending on the loading rate of the mixed material or the eye weight of the field worker, so that the mixing ratio cannot be constantly adjusted to an appropriate value while the excavator or generalized screw type As the mixing process proceeds using a mixer and a cylindrical mixer, the mixed materials are not sufficiently mixed in a uniform distribution.

Therefore, the applicant has previously registered a "patterned aggregate mixing device for the repellent layer of landfill" which mixes the aggregate, the mixed material, and the water or the emulsifier in a uniform blending ratio and water content as a Korean Patent No. 10-0629458.

As a prior art that is applied to the conventional aggregate mixing process to perform the improvement and sorting function of the recycled aggregate, Korean Patent No. 10-0596615 (reclaimed aggregate type improvement and sorting device using a flush rotary fan) has been proposed, but The prior art replaces and repairs due to the severe wear phenomenon of the striking plate and the stabilizing plate, as the striking plate for hitting the mortar or flagella on the regenerated aggregate is installed on the fixing piece welded to the outer periphery of the rotating shaft. This is difficult and excessively expensive operating conditions.

In particular, the above prior art performs the improvement of the aggregate of the aggregate by rubbing the mortar or flagella attached to the recycled aggregate continuously inserted only by the low speed rotation of the striking plate and the friction between the aggregates, so that the effect is lowered and the operation cost is excessively increased. In addition, in the continuous process, the improvement of the granularity of the aggregate is not much lower than expected, and there is only a simple friction function without the shredding mixing function of the aggregate.

The present invention has been made in order to improve the problems of the aggregate aggregate and crushing process in the conventional aggregate mixing process and crushing process, the aggregate and the aggregates continuously injected in the aggregate mixing process by the shaft and crushing blade to rotate at high speed Abrasion blades are attached to the shaft by applying a centrifugal force to the shaft to increase the processing capacity by increasing wear efficiency and mixing efficiency of aggregates and significantly reducing power consumption due to wear.
