As is well known, artificial marble is a material having characteristics such as excellent appearance, soft texture, excellent weather resistance, and the like, and the demand for various interior materials continues to increase.

On the other hand, waste materials generated in the manufacturing process of such artificial marble and artificial marble products which have been disposed of after being used as a building or furniture are treated as industrial waste, and thus have to be landfilled or incinerated, thereby causing environmental pollution, raw material waste and disposal. The cost is increasing.

Generally, artificial marble includes a predetermined amount of resin and aluminum hydroxide, where aluminum hydroxide is used in various industrial fields as a flame retardant, and in order to recycle it, waste artificial marble must be finely powdered to a predetermined size or less.

That is, as a method for using waste artificial marble, it can be added to paint raw materials, artificial marble raw materials, and products requiring flame retardancy. In order to use them, waste artificial marble should be pulverized into fine powder of 400 mesh or more. In this case, the mesh is a unit representing the number of body eyes within 1 inch, and the larger the numerical value, the smaller the particle size.

Conventionally, waste artificial marble is pulverized into a powder form through a pulverizing apparatus using ordinary physical friction, and fine powder is produced by passing a screen net having a predetermined size or less.

However, high frictional heat may be generated in the pulverizer because the pulverizer must be operated for a long time in order to pulverize the waste artificial marble and fine powder below a predetermined size. In addition, due to the frictional heat, the resin contained in the waste artificial marble melts and sticks to the inside of the crushing apparatus and the screen net to contaminate the crushing apparatus, and the output pipe connected to the screen net may be blocked, resulting in overheating of the motor. There was a problem that a failure occurs in the device.

There was a problem that occurred.

In addition, the waste artificial marble powder which is not pulverized to less than a predetermined size in the air crusher gathers inside the screen network, and the output pipe is clogged, resulting in a failure of the motor overheating and the crushing apparatus due to this, and there is also a problem in that the crushing efficiency is lowered.

Thereafter, the temperature sensing unit 500 detects the temperature of the air crushing apparatus 300 (S105), and the temperature detected by the temperature sensing unit 500 in the central controller 700 is a preset reference temperature. If abnormal, the cooling device 800 is operated to cool the heat generated from the air crushing device 300 (S106 to S108).

The central control unit 700 is a device that collectively controls the supply device 100, the pre-crusher 200, the air-crusher 300, and the output device 400 of the present system. It can be configured with a conventional microprocessor, CPU, MPU and the like.

The key input unit 600 inputs a user's command and various setting values to the central control unit 700. That is, a reference temperature value for determining the operation of the cooling device 800 may be input. In addition, it is possible to input a reference amount of the output amount to be described later. The input value is stored in a conventional memory (not shown) and read and used by the central controller 700 whenever necessary.

The cooling device 800 cools the heat generated by the pre-crusher 200 or the air-crusher 300. The cooling device 800 may selectively use air-cooling or water-cooling using cooling water using ordinary air, and in one embodiment of the present invention, the pre-crushing device 200 or the air-crushing device 300 is used by using water cooling. ) Was allowed to cool.

To this end, the cooling device 800, the pre-crushing device 200 or the air crushing device 300 is formed in close contact with the cooling water circulating cooling water 810 therein; A water pump 820 supplying cooling water; An input pipe 821 for inputting the cooling water supplied from the water pump 820 into the cooling tube 810; And a recovery pipe 822 which recovers the cooling water circulated through the cooling cylinder 810 and heat-exchanged to the water pump 820.

Finally, the output device 400 performs the step (S109) of outputting the waste artificial marble pulverized in the fine powder in the air crushing device 300 to the outside, and the output device 400 in the output amount detection unit 900 Detecting the output amount of the finely divided waste artificial marble output from the (S110), if the output amount detected by the output amount detection unit 900 in the central control unit 700 is more than a predetermined reference amount the supply device 100 Control the supply to reduce the supply amount, if the reference amount is less than the supply amount is increased (S111 ~ S113).

In this case, the central controller 700 may control the rotation speed of the fan (not shown) of the supply device 100 or control a separate input means (not shown) to adjust the supply amount.

Since the output amount detection unit 900 can be easily configured using a conventional technique for detecting the weight, volume or density of the powder, a detailed description thereof will be omitted.

Here, the size of the powder that is high-pulverized by the air crushing device 300 is preferably 300 to 500 mesh (mesh) within. In addition, the fine powder waste artificial marble output from the output device 400 may be collected through a conventional bag filter (not shown) and packaged into a product of a predetermined unit.

Therefore, the present invention is because the finely ground waste artificial marble containing the resin in the crushing device using the physical friction and then pulverized by a high-speed rotating air crushing device using the impact of the high-speed rotating air to efficiently produce fine powder without sticking In addition, the resin contained in the artificial artificial marble melts and adheres to the inside of the crushing apparatus and the screen net to contaminate the crushing apparatus, or the output part connected to the screen net is blocked, thereby preventing the motor from overheating and the failure of the pulverizing apparatus.

In addition, in order to use the air crushing apparatus, there is no need to add a separate operation of pulverizing the waste artificial marble to a predetermined size or less, and in advance that friction heat is generated by a cooling device that is automatically operated at a predetermined temperature. It can also be prevented.

In addition, by collecting and re-pulverizing the waste artificial marble powder collected at the bottom of the screen net of the air crusher output pipe, the output pipe is prevented from being clogged and the crushing efficiency can be further increased.

Therefore, by finely pulverizing waste artificial marble as described above, it can be recycled into various types of artificial marble, and mixed with other materials to be used in various applications such as flame retardant materials or wire coating, thereby producing approximately 10 to It can reduce the disposal cost of waste artificial marble by 15%, prevent the environmental pollution from disposal, and at the same time achieve the economic effect of obtaining raw materials, landfill problem and industrial effect to prevent soil pollution. .

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
