Description

{A crushing system of aggregates crushing and particle-spectic collection}

The present invention relates to a crushing system capable of crushing aggregates and collecting particles, and more particularly, to a crushing system of a new structure capable of collecting particles as well as aggregates.

Waste concrete generated during the demolition of the structure is recycled through the intermediate treatment process for collecting the aggregate. The general intermediate treatment process involves a crushing process that crushes the aggregate to the aggregate size for recycling by applying a multi-stage crushing process, · A series of continuous processes such as a separation process for separating and separating reinforcing bars and foreign substances by using manpower, a screening process for separating the screen into various size by recycling application and a particle size control process .

Waste concrete intermediate treatment process for high-grade purpose is mainly divided into production process of recycled aggregate for roadside auxiliary layer and recycled aggregate production process for concrete.

The recycled aggregate production process for the roadside auxiliary layer can satisfy the quality technology by performing basic processes such as crushing and separation and removal of foreign substances to match the granularity. However, the recycled aggregate for concrete, which is a more advanced use, Or the strength of the concrete structure, the aggregate density should be 2.5g / ㎤ or more, the water absorption rate should be 3.0% or less, and the high quality standards such as other performance ratio and the foreign matter content should be within the standard To this end, a separate process is applied.

Concrete aggregate density and water absorption, which are factors affecting the quality (strength) of concrete in relation to the quality of recycled coarse aggregate, are greatly influenced by the amount of mortar contained in the recycled aggregate and the degree of cracking in the aggregate. That is, when the amount of mortar adhered to the aggregate increases, the water absorption rate increases and the density tends to decrease. Also, even when a large number of cracks are generated in the crushing process, the density of the aggregate increases, The compressive strength tested by replacing the aggregate by 30% shows a remarkable decrease.

Therefore, the additional process for producing recycled aggregate for concrete with good quality requires effective separation and removal of the adhered mortar while minimizing the damage of aggregate. To this end, in addition to the intermediate treatment for the production of recycled aggregate for road construction, And a screening process accompanying each process.

On the other hand, the amount of ascon used in Korea is about 28.4 million tons, but it is neglected due to lack of expertise and lack of recognition of its importance.

Particularly, the average life span of the aggregate, the ascon production and the construction quality has been lowered due to the quality control problem, and after the concentrated rainfall in summer, the damage problem such as the porthole occurs.

The problems associated with the aggregate for ascon are as follows.

First, compared with concrete aggregate, the amount of ascon is much smaller, while the demand for stricter conditions is greater than that of concrete aggregate.

Second, although there are about 300 sites in the country, there are 300 different sites in the country, but aggregates are produced through unequal equipments and routes for each mountain, and the grain size and shape variation of the aggregates supplied to the plant are very large. It has a big influence.

Third, there is not enough institutional device to manage the quality of aggregate.

Fourth, there is a difference in the specification of aggregate stored in cold bean for each asphalt plant. Therefore, it does not produce aggregate according to the aggregate specification (No. 7, No. 8, No. 78) of asphalt mixture in Pyeongsan, And there is a problem that it is produced by using the remaining aggregate.

Fifth, there is a problem of regulation of aggregate type for asphalt mixture, and there is a problem that even a simple experimental apparatus for measuring the granular stone is not provided.

Accordingly, the present invention provides a system for improving the quality of a concrete mixer / ascon, and more particularly, it relates to a system for separating asphalt from an aggregate which can separate a desired size of aggregate from an aggregate, It is an object of the present invention to provide a crushing system capable of collecting particles.

A plurality of holes are formed on the surface of each of the plurality of roller units 100 And the aggregate crushed through the holes is drawn into the roller unit 100 and then discharged to the outside of the crushing chamber 10. [

The aggregate flows into the aggregate input port 11 by the rotation belt C provided separately on the outside and the aggregate introduced into the aggregate input port 11 is crushed by the plurality of roller portions 100, The aggregate left to be conveyed to the collecting unit 300 is discharged by the aggregate discharge port 12 located at the lower end of the aggregate collecting unit 300 and then collected by the aggregate collecting container 20 provided separately, And is constituted in a circulating manner.

The present invention is characterized in that a plurality of roller units 100 provided at an angle to the crushing chamber 10 are installed.

The reason why the aggregate materials are inclined at a predetermined angle from left to right in the drawing is that the aggregate materials flowing into the roller unit 100 through the plurality of holes formed on the surface of the roller unit 100, It is for the purpose of making it.

That is, due to the rotational movement of the plurality of rollers themselves and the upward and downward movement between the plurality of rollers, the aggregate materials flowing into the aggregate material inlet port 11 are crushed, and the crushed aggregate materials are passed through holes And is naturally moved to the collecting part 300 formed on the right side by the inclined angle after being introduced.
