The crushed aggregate can be easily prepared in a form suitable for the material of the concrete because the surface thereof can be polished and segregated through the aggregate polishing part.

At this time, since the foreign matter on the surface of the aggregate can be washed through the washing water sprayed on the aggregate polishing part, a more suitable aggregate can be provided as the material of the ready-mixed concrete.

Since the aggregate discharged from the aggregate polishing portion is discharged to the discharge portion in a state of being stacked by the weight value set by the opening / closing means, the aggregate can be easily metered by the weight value used for manufacturing the ready mixed concrete.

In particular, when the weight value of the stacked aggregate reaches the set weight value, the open / close panel in which the aggregates are stacked is in an open state. At this time, the crushing portion, the aggregate material grinding portion and the washing water dispersing portion are stopped Therefore, the addition of aggregate other than the aggregate necessary for manufacturing the concrete can be prevented.

When the weight value of the stacked aggregate is less than the set weight value, the opening / closing panel is closed. In this case, the washing water having washed the aggregate is moved through the inclined surface of the opening / closing panel, the guide rail, and the guide hole And can be easily accommodated in the wash water collecting portion. That is, it is possible to prevent the washing water used for washing the aggregate from being discharged through the discharge portion.

The washing water collected in the receiving space through the washing water collecting unit passes through the filter net to filter the foreign substances and provide the purified washing water. The purified washing water can be reused as the water required for manufacturing the ready-mixed concrete, There is also.

The controller 170 is configured to control the respective components connected via wire / wireless as described above, and may be configured as a conventional controller 1131 having a PCB substrate. The controller 170 may communicate with each of the above-described components via wire / wireless and may control operations of the respective components.

Here, the controller 170 can control the respective components through the set system. The control unit 170 will briefly explain the aggregate supply process and the concrete manufacturing method using the plant 100 capable of forming the aggregate, which will be described later.

First, an aggregate supply process for supplying an aggregate formed by molding a raw material through the aggregate supply chamber 110 to the transfer unit 150 will be described with reference to FIG.

First, the raw material of the aggregate is introduced into the hopper 112. At this time, the raw material may be supplied from the storage as described above, or may be directly supplied through a separate supply means by the operator.

Next, the raw material charged into the inner space of the housing 111 through the hopper 112 is supplied to the crushing section 113. Accordingly, the raw material can be provided in a size suitable for the material of the ready-mixed concrete while being broken by the roller 1131 of the crushing portion 113.

Here, the dust generated when the raw material is broken may be sucked by the suction unit 114, and the sucked dust may be collected and removed, or the foreign matter may be discharged through a filter or the like.

Then, as described above, the aggregate material provided through the crushing section 113 falls and is supplied to the aggregate material polishing section 115 disposed below the crushing section 113.

Next, the aggregate supplied to the aggregate polishing unit 115 flows into the inner space of the second rotating body 1154 through the through hole 1154b. The aggregate can be moved along the rotating direction of the first rotating body 1152 or the second rotating body 1154 between the first rotating body 1152 and the second rotating body 1154, Through the through hole 1154b positioned at the bottom, and can be discharged to the outside of the aggregate polishing unit 115. [ The aggregate collides with the abrasive protrusions 1152a and 1154a of the abrasive member 1155, the first rotating body 1152 and the second rotating body 1154 provided in the inner space of the second rotating body 1154, And the segregation can be removed at this time. The aggregate can be cleaned with foreign substances or the like adhered to the surface by the washing water sprayed from the washing water dividing section (116).

Next, as described above, the polished aggregate falls and is separated by the opening / closing means 117 provided at the lower portion of the aggregate polishing portion 115, between the aggregate polishing portion 115 and the discharge portion 119, Respectively. The aggregate is gradually stacked on the upper portion of the opening / closing panel 1171 until the weight value reached through the load cell 1172 is reached, and the surface can be dried by the hot air fan 118 in the stacked state. At this time, the opening / closing panel 1171 is supported by the rod 1173a of the cylinder 1173, which is in the contracted state, so that the aggregate can be fixed to be stacked.

Next, when the weight value of the aggregate material stacked on the opening / closing panel 1171 reaches the set weight value range, the control unit 170 controls the opening / closing of the passage between the aggregate material polishing unit 115 and the discharge unit 119 The panel 1171 is rotated in the downward direction. At this time, the aggregate falls as the opening / closing panel 1171 is rotated, and is discharged to the outside of the housing 111 through the discharge portion 119.

The control unit 170 compares the weight value of the aggregate transferred through the load cell 1172 with the set weight value and if the weight value is greater than the weight value of the aggregate, 1173 to turn the opening and closing panel 1171 and at the same time stop the operation of the crushing section 113, the aggregate material polishing section 115 and the washing water dispersing section 116. This is to block the supply of additional aggregate while the open / close panel 1171 is in the open state, and to prevent the sprayed wash water from being directly transferred to the discharge unit 119 without passing through the open / close panel 1171.

The controller 170 operates the cylinder 1173 to turn the opening / closing panel 1171 so that the opening / closing panel 1171 is closed when the predetermined time passes since the opening / closing panel 1171 is opened At the same time, the crushing section 113, the aggregate material polishing section 115, and the washing water dispersing section 116 are operated. This is to stack the aggregate again by the set weight value while the opening / closing panel 1171 is in the closed state.

On the other hand, the washing water washed with the aggregate can be moved to the surface of the opening / closing panel 1171 while the aggregate is stacked as described above, and is guided along the guide rail 1171a of the opening / closing panel 1171 to the guide hole 1171b. And can be moved to the center of the collecting body 121 of the washing water collecting container 120 through the guide hole 1171b.

The washing water moved to the upper center of the collecting body 121 moves downward along the upper inclined surface and flows into the inner space of the collecting body 121 through a plurality of inflows provided on the collecting body 121 . The washing water may be filtered by foreign matters in the internal space of the collecting body 121 and the purified water may be filtered and moved to the internal space of the mixing chamber 160 along the guide pipe 123 . The wash water may be introduced into the guide pipe 123 only by a certain amount by the check valve V controlled by the control unit 170.

It is possible to easily improve and supply the formed aggregate as much as the predetermined weight value through the above-described aggregate supply process, to mold it into a size suitable for the ready-mixed concrete, to remove the dust generated during the process, The washing water can be purified and reused, and the purified washing water can be supplied by improving the amount of water required for the ready mixer.
