Description
The present invention relates to an aggregate which satisfies the quality standard of road construction recycled aggregate and which is separated and removed in two stages by mortar contained in waste concrete by a serial twin type cylindrical drum crusher to produce high quality recycled aggregate for concrete, The present invention relates to a production apparatus and more particularly to a production apparatus and a manufacturing method thereof in which a spiral protrusion is formed in a fixed liner attached to an inner wall of a horizontal fixed cylindrical drum and a density and a lead angle of spiral protrusions formed on the fixed liner of the first- The primary crusher performs crushing of aggregate and mortar, the secondary crusher removes mortar with aggregate surface, and performs the crushing function to improve the shape of the aggregate, thereby improving the productivity of recycled aggregate for concrete and improving the quality Recycled coarse aggregate production site for concrete using serial twin type cylindrical drum crusher Relate to.
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 or foreign materials by using manpower, a sorting process for separating the screen into various size by recycling purpose 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.
In this study, we investigated the characteristics of recycled aggregate concrete for construction site and the practical use of it.
As shown in Table 1, the wave crushing process applied in the process of producing recycled aggregate for concrete is a combination of compressing, impacting, friction, impact and friction mixing, Mills, and devices using crushing and milling of cylindrical drums. These devices are combined with a sorting device for separating crushed materials to form a recycling aggregate production system for concrete.
In general, the compression method is a method of crushing a large quantity by applying repetitive mechanical pressure. It is a jaw crusher or a cone crusher, and has a high crushing efficiency. However, it has a disadvantage of damaging the aggregate circle, It is mainly applied to pre-treatment of recycled aggregate production for concrete, that is, primary to tertiary pulverization process of intermediate treatment process.
Impact method is a method of separating by using the difference of crushing amount of impact of mortar surrounding aggregate and aggregate by hitting aggregate by using hammers or rotors rotating at high speed and effectively separating mortar by repeatedly applying appropriate impact force. It is possible to maintain the aggregate circular shape at the time of application together with the heat treatment, but there is a disadvantage in that the productivity is not high as compared with the compression method and the uniformity of the quality is lowered in the continuous type structure in which the hammer or the rotor is applied to the cylindrical drum. There is a limit in that it is necessary to compensate for the improvement of the water absorption rate, density and shape.
The friction, friction, and impact mixing methods include a ball mill or a roller mill, or a method in which a screw is provided on an inner or outer rotary drum such as a ball mill or a roller mill, or in Korean Patent No. 10-1118580 and No. 10-1194661, It is possible to increase the effect of peeling mortar and to improve the shape of the mortar by applying it to the final stage of the coarse aggregate, but the productivity is low.
In order to overcome the limitations of the prior art, the present inventors have proposed an aggregate crusher (Korean Patent No. 10-1277525) which is provided as a twin type, in which two cylindrical drums are horizontally fixed on one lower deck And an aggregate material inlet for dispersing / injecting the aggregate material is disposed at one side of the two cylindrical drums, and a processed aggregate discharge portion is provided at the other side of the cylindrical drum, and an elliptical unitary fixed liner is provided at the wall of the horizontal cylindrical drum The unitary fixing liner has a protruding portion formed at the central portion of the horizontal cylindrical drum. The unitary locking liner has a rotation center axis at the center of the horizontal cylindrical drum, a plurality of branching shafts extending in the longitudinal direction of the rotation center axis, The side has a plate-like shape with an inclination in the range of 1 to 5 degrees And the inclined angle control device is provided at one side of the lower deck. The inclined angle of the inclined angle of the inclined angle of the inclined angle of the cylindrical drum And the crushed aggregate is passed between the flow liner and the fixed liner, and the impurities of the aggregate are separated and separated from each other. Wherein the aggregate introduced through the inlet is crashed into the conveying liner and the fixing liner and crushed while being crushed while the crushed aggregate passes through the gap between the flow liner and the fixing liner, The mortar or cement paste in the aggregate And the impurities are desorbed to provide good aggregate production capability.
However, since the above-mentioned technique is constituted by the inclined angle applied to the slope and the conveyance liner applied to the cylindrical drum and the rotation of the central axis is maintained at 200 to 300 RPM which is relatively high, And 40 to 50% of the input waste concrete is a raw material amount of the circulating coarse aggregate for concrete, which is divided into two cylinders By crushing the pulverized material on the drum, there is a limit to the quality improvement due to the relatively low chance of mortar separation due to collision and friction between the aggregates in addition to the impact with the apparatus.
In addition, in the above-described technique, the protruding portion formed to be convex in the fixed liner is formed in a straight line shape, so that the separated mortar is filled in the concave portion to buffer the action, so that the crushing effect is reduced, and the fixed liner attached to the inner wall of the cylindrical drum As a result, the maintenance cost for replacing the whole part at the time of partial wear is high, and since the input aggregate is treated mainly by the primary impact with the fixed and flowing liner, the detachment of the adhering mortar is limited, There is a limit in improving the quality of the circulating coarse aggregate.
In the present invention, the structure of the "aggregate crusher provided as a twin type" proposed by Korean Patent No. 10-1277525 is separated into a first crusher and a second crusher, and the first crusher is improved in series, The mortar is crushed by crushing the aggregate and the mortar, and the mortar separated from the first crusher is selected and removed to limit the secondary crusher input aggregate to the recycled aggregate. However, by the friction mechanism between the liner and the aggregate and the aggregate In order to produce the recycled coarse aggregate for concrete by constructing to perform the crushing function, the objective is to improve the efficiency of the whole system and to improve the quality by the stepwise processing.
In addition, since the feeding of the aggregate is performed on the wall surface of the cylindrical drum, the crushing and grinding mechanism is uniformly applied to the entire aggregate, and the aggregate circular deterioration due to the impact is minimized and the aggregate and the mortar interface are separated So that the quality uniformity of the recycled coarse aggregate for concrete can be secured.
Another object of the present invention is to provide an aggregate shredder capable of reducing the maintenance cost by improving maintenance of the branch shaft, the fixing liner, and the flow liner structure as consumables, Respectively.
In order to achieve the above object, the present invention provides a circulating coarse aggregate production apparatus for concrete using a twin-type cylindrical drum crusher, comprising a cylindrical drum having an aggregate input port formed at one side thereof and an aggregate discharge port formed at the other side thereof, And a unit fixing liner is vertically and horizontally connected and fixed to the inner wall of the cylindrical drum. A rotation center shaft connected to the motor is installed at the center of the cylindrical drum, and a plurality of branch shafts The aggregate crusher for constructing the aggregate crusher for concrete is constructed by using the aggregate crusher having a structure in which a flow liner is attached to each branch shaft end portion so as to have an inclination angle toward the aggregate outlet, And a first separator connected to each crusher and a second separator connected to each crusher So that the crushed material having a small size among the crushed materials by the first crusher is filtered by the first crusher and put into the second crusher in a state where the crushed material is previously removed and the crushed material of the crushed material by the second crusher And the second separator separates and removes the coarse aggregate for concrete, wherein the unit fixed liner surface attached to the inner wall of the cylindrical drum of each crusher described above is formed into a spiral The spiral protrusion functions as a spiral protrusion of the spiral protrusion applied to the primary sprinkler to relatively increase the lead angle and density of the spiral protrusion applied to the secondary sprinkler, , And the secondary crusher is configured to perform a function of crushing the charged aggregate surface, Each of the branch shafts coupled to the

In the present invention, the spiral protrusions formed on the unitary fixing liner of each crusher constitute a continuous spiral from the aggregate input portion toward the discharge side by the sequential assembly of the unit fixing liner, and the spiral protrusions By increasing the lead angle and density of the spiral protrusions applied to the primary crusher, wave crushing by the impact of the aggregate and the spiral protrusion is mainly performed in the primary crusher. In the secondary crusher, the aggregate rides on the slanted contact surface of the spiral protrusion As the slip is increased, the amount of friction contact increases, so that the mortar and crushing of the crushed parts of crushing are mainly performed. Therefore, it is possible to produce circulating coarse aggregate for high quality concrete without any additional process.
In addition, the cylindrical drum constituting each crusher is fixed horizontally, so that the lateral directional transfer, that is, the transfer from the aggregate input port to the discharge port, is performed by the lead angle applied to the flow liner and the lead angle applied to the fixed liner spiral protrusion, And the majority of the aggregate is gradually transversely conveyed at the deep depth of the cylindrical drum which is the fixed liner close-up part, so that it is exposed to the collision and friction necessary for crushing or grinding while passing through the cylindrical drum, And coarse aggregate quality stability can be ensured.
The first separator is connected to the first separator at the downstream end of the first separator, and is introduced into the first separator to separate small particles having a high specific gravity of about 60% of the crushed aggregate by a first separator Only the aggregate of about 40% is transferred and fed into the second crusher, the surface-adhered mortar is removed by the crushing mechanism of the second crusher, and the mortar and the finely divided material desorbed by the second separator are removed, And the second stage of the crushing process, the load can be stably managed and the production efficiency can be improved.
In addition, since the fixed liner is divided into a base and a surface portion, it is possible to replace only the surface portion at the time of abrasion, and the lead angle can be adjusted by the insert when the lead angle applied to the flow liner is adjusted. And the fixing liner, the branch shaft, and the flow liner are respectively coupled by the fastening structure, thereby facilitating maintenance.

As shown in FIG. 4, the fixed liner
The spiral protrusion density of the first crusher is 10 times higher than that of the second crusher and the lead angle of the spiral protrusion is 0.63 rotation from the aggregate inlet to the discharge portion of the first crusher, The car crusher has a structure in which the lead angle and density of the
The spiral protrusions formed on the fixed liner of each crusher are crushed by the collisional contact of the aggregate and the spiral protrusions against the rotation flow of the aggregate formed by the rotation of the flow liner.
The flow liner has an action of pushing the aggregate material into the center of the rotary drum close to the fixed liner by mixing the shape of the square plate formed at the end of the branch shaft and the inclination angle (lead angle) applied to the plate, the action of hitting the aggregate material in the circumferential direction, And pushing the aggregate in the upper portion of the cylindrical drum to induce collisional fracture between the upper fixed liner and the aggregate.
5, assuming that the aggregate located in the primary crusher is traveling on the inner wall of the fixed liner, the aggregate of the secondary crusher is subjected to at least 16 contact shocks with the
In addition, the aggregate located in the first crusher approaches and collides with the
According to this principle, the aggregate is directly pulverized by the first crusher, and in the second crusher, the crushing mechanism by the friction contact occurs rather than the crushing of the aggregate, so that the crushing of the mortar attached to the aggregate surface and the crushing The area is crushed to provide a grain improvement effect.
The cylindrical drum constituting each crusher is horizontally fixed so that the lateral directional transfer, that is, the transfer from the aggregate input port to the exhaust port, is effected by the lead angle applied to the flow liner and the lead angle operation applied to the fixed liner spiral projections.
A part of the aggregate flowing into the cylindrical drum is directly contacted with the rotating (200 to 300 rpm) flow liner and is scattered to the upper part of the cylindrical drum, collides with the upper fixed liner and is transported in the lateral direction by the lead of the spiral projection. Only the aggregate located in the lower portion of the cylindrical drum and close to the lower fixing liner contacts with the lower fixing liner spiral projections to perform lateral transfer inside. Therefore, most of the aggregate is transported in the transverse direction gradually compared to the method of inclining the cylindrical drum, which has been previously proposed, and is exposed to the collision and friction necessary for crushing or milling while passing through the cylindrical drum. It is possible to secure the quality stability of the aggregate.
The difference between the spiral protrusion densities and the lead angles of the first and second secondary crushers described above provides the difference in throughput with the difference in the amount of collision between the aggregate and the spiral protrusion required for crushing. That is, the primary crusher is mainly made of crushing and rapidly crushes a large amount of aggregate by a large lead angle, the secondary crusher is mainly made of crushing, and a relatively small amount of aggregate is crushed by a small lead angle for a longer time It can reasonably reflect the mass balance of the entire process from the input of waste concrete to the production of the final recycled coarse aggregate, and consequently provides efficiency of production.
Considering the mass balance of recycled coarse aggregate production equipment for final concrete, it is desirable to design the system so that 10 to 15% of the input waste concrete is recycled as recycled coarse aggregate for concrete. Of the raw material and then injecting it into the circulating coarse aggregate production facility for the final concrete to separate and remove about 65% of the mortar and the fine material, and then to produce circulating coarse aggregate for about 35% of the concrete.
The present invention is characterized in that a first separator is connected to a downstream end of a first crusher and is introduced into a first crusher to separate small particles having a high mortar specific gravity by about 60% And only about 40% of the aggregate is transferred to the second crusher, and the surface mortar is separated by the mechanism of crushing it again in the second crusher. The mortar and the finely divided material are shaken by the second separator, It produces 10 ~ 15% recycled coarse aggregate for concrete compared to concrete.
Therefore, the present invention is compatible with the material balance of the intermediate treatment whole system, and it is possible to maintain the quality stability by stably managing the load by the grinding and the grinding two step process.

By separating the fixed liner into the base (32) and the surface portion (33), when the spiral protrusion wear is progressed mainly, only the surface portion is replaced by maintaining the base, maintenance is easy and the wear amount of the spiral projection and the fixed liner surface So that the maintenance cost can be reduced.
