Description

Technical Field [0001] The present invention relates to a crusher for crushing construction waste,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for crushing aggregate generated in a construction waste, a quarry or a mine. More particularly, the present invention relates to a crusher for crushing aggregate primary crushing and cement paste by crushing and striking by a combination of a roll crusher and a jaw crusher To a crusher for intermediate treatment of construction waste and a two-stage crusher by batting, in which secondary crushing and cement paste are peeled off with fine aggregate as the primary crushed aggregate by hitting by hammer.

High-rise and large-scale facilities built in high growth period since economic development and Dongdong houses are now getting old and redeveloped and reconstructed. The demand for new construction for housing supply is also steadily increasing, and a rapid increase in the amount of construction waste is inevitable reality. According to the Ministry of Environment 's press release in 2000, the amount of construction waste accounted for 34% of total industrial waste, and the amount of waste concrete increased from 23,577 tons / day in 1996 to 71,063 tons / day in 2000. 99,900 tons / day in 2010 and 289,470 tons / day in 2020 are estimated to occur.

Construction wastes are different from municipal wastes and industrial wastes. And the characteristics are different according to the step that is generated. Construction wastes are very bulky and heavy and require huge transportation and landfill costs during transportation and landfilling. They are inconsistent throughout the year and occur in large quantities at certain times during reconstruction. The construction waste is recycled by more than 80% through intermediate processing companies, but the recycling rate is actually lower due to the quality problems of the produced aggregate and the problem of the user's recognition.

Accordingly, in case of the application of the law related to the contract with the state party, it is necessary to use the recycled aggregate for the owner. In December 2003, the "Act on the Promotion of Construction Waste Recycling" In August, "Recycled aggregate quality standard" was finalized, and since January 1, 2007, recycled aggregate quality certification was carried out. As a result, recycled aggregate producers increased the quality of recycled aggregate and construction companies promoted recycling of recycled aggregate. An institutional basis for the development of development has been established.

Particularly recently, the Ministry of Land, Transport and Maritime Affairs has recently amended the "Enforcement Regulations for the Promotion of Recycling of Construction Waste", and its main content is to separate waste asbestos from other construction waste, Ascon is regulated to be used directly as a raw material for recycled ascon, and it is focused on recycling with high added value of recycled ascon. However, the development of pretreatment processes for the recycling of waste concrete and waste asbestos has been insufficient. In this pretreatment process, crushing and classification is an important part of recycling spent concrete and waste ascon.

The crushing (grinding) technology is a core technology for recycling waste asbestos and waste concrete. The crushing process is a process that generates a lot of energy consumption, and even if it produces powder with the same particle size, Technology is needed. Crushing of aggregate occurs by applying stress to aggregate and crushing device is a device that induces stress enough to cause crushing. The form of stress is compression, impact or shear, and it can induce fracture by consuming the least amount of energy by giving proper type of stress according to the physical properties of the aggregate. In addition, the way to stress the particles is influenced by the particle size. If the particle size is large, the individual particles are possible. However, if the particle size is small, the particle does not act as a wing but forms a group of particles. The amount of stress given to the individual particles is relatively reduced, and effective grinding does not occur. Therefore, the crushing equipment is designed differently according to the grain size.

However, no suitable crusher has been developed to produce recycled aggregate by crushing waste concrete and waste ascon. Therefore, if this technology is applied to the industrial field, the following expected effects can be created.

① It will provide the basis for the most efficient and economical production of recycled aggregate required by the construction waste disposal company and the Ascon recycling company.

② It is possible to provide economic production technology of recycled aggregate for each construction waste, which will greatly improve the competitiveness of related industries.

③ We can expect to improve the competitiveness and economic efficiency of the industry by locally producing high-quality crushing technology that depends on imports.

④ By recycling construction waste as a high quality recycling resource, the environmental burden can be reduced.

As a result, many companies are producing aggregate, but due to lack of technology and awareness, the necessity of recycling of aggregate has become unavailable. Each construction company avoids low grade aggregate and the aggregate is limited to use as soil and embankment. It is wasteful.

As such, the aggregate coated with the paste and the coating material can not be used as a high-quality material such as aggregate for concrete, and has a disadvantage that it can only be used for a simple landfill or an auxiliary soil layer.

In order to solve such drawbacks, there have been proposed techniques for removing the paste and the coating material by using a chemical agent, but the cost of using the chemical agent is constantly increased and the burden is increased and the environment can be contaminated .

In order to solve such a problem, Patent Document 1 (Patent Registration No. 10-0941410) which has been patented by the present applicant is available.

Patent Literature 1 is small in that the aggregate is crushed and peeled off by the impact of the swing jaws and the rolls, but the crushing efficiency and the peeling efficiency are high, which is advantageous in producing high-quality aggregate. However, There is a disadvantage that separate crushing and peeling treatment are required in order to produce high-quality aggregate because there are items that are not satisfied.

The aggregate A having been subjected to a pretreatment process or the like is fed into the hopper 230 and is fed to the distributor 233 along the feeder 232 and fed to the distributing projections 233b and the distributing holes 233c through the distributor 233 And is dropped between the swing jaws 212 of the primary crusher 200 and the rolls 222.

2. Primary shredding.

The primary crush is crushing by swing jaws 212 and rolls 222. The roll 222 is in a rotating state and the swing jaw 212 is reciprocated back and forth with respect to the roll 222 and thus the aggregate A is crushed to a small particle size and the paste on the surface of the aggregate (A) is peeled off.

3. 2nd shredding.

The aggregate B primarily crushed by the primary crusher 200 by compression and striking is introduced into the secondary crushing tank 310 of the secondary crusher 300. First, the striking of the secondary crusher 300 and the angle of the peeling adjustment hole 340 and the discharge guide 350 are set and prepared.

The second aggregate B is disposed in the secondary crushing tank 310 through the inlet 311 of the secondary crushing tank 310 so that the hammer 330 rotating inside the secondary crushing tank 310 is discharged through the aggregate B) to be crushed secondarily.

Specifically, when the aggregate B is hit by the hammer 330, the aggregate B is broken by the impact energy toward the liner 360, and when colliding with the liner 360, Lt; / RTI > The crushed aggregate colliding with the liner 360 is again hit by the hammer 330 and crushed and scattered. This process is performed in multiple stages according to each part of the secondary crushing tank 310, And the angled portion is removed, and the shape of the die is improved.

In addition, the aggregate passes through the striking and peeling adjustment hole 340 before being discharged, and in this process, the hammer 330 and the striking and peeling adjustment hole 340 are broken by blowing or grinding to remove the paste.

The crushed aggregate is discharged through the discharge port 312. The crushed aggregate is discharged from the discharge port 311 toward the discharge port 312 in accordance with the angle between the impact and separation adjustment port 340 and the discharge guide 350, Or may be discharged through the discharge port 312 immediately after being crushed or rebounded by the strike and peel adjustment port 340 and the discharge guide 350 so as to rise toward the upper charging port 311 and rotate one or more times And is crushed by the discharge port 312 after being crushed.

It was confirmed that at least 90% of the recycled aggregate produced by the present invention exhibits the original aggregate color as it is.

Since the hammer type secondary crusher 300 according to the present invention performs crushing by hitting the hammer 330, hitting by the hammer 330, striking by the striking and peeling adjustment hole 340, and peeling of the paste, Or may be used alone without being used together with the battery 200.
