Description

A crushing apparatus for crushing and particle-collecting aggregates.

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