Cathode Ray Tube Separation plant Dry cutting

End of life televisions have to be recycled. The C(athode) R(ay) T(ube) has to be separated in a front and a rear part. In order to do that the housing of the TV has to be removed. This has to be done manually. During the years a lot of dust is gathered in the TV. This dust is harmful when inhaled. Therefore it is necessary that the housing is removed in a well-ventilated room with filters collecting the dust. After removing the housing the CRT has to be placed in the machine. ATN has two types of machines to do the job. For small capacity dismantling we have the CRT-L and for high capacity we have the CRT-H.

CRT.L

In the CRT.L the metal band of the tube is removed first. Then the CRT is moved to the second stop where the CRT is cut into two pieces with the help of 4 disc-cutters. In order to avoid dust of the cutting coming into the working area of the operator the CRT is lowered into a separate area in the machine. From here the dust is exhausted away from the operator. After the cutting the parts are moved to the third station in order to remove the back and the phosphorous layer inside the front-glass.
In the CRT is toxic material in the phosphorus layer on the inside of the CRT. Also it is important to separate the glass from the front and the rear. The rear glass contains led. The front is very good to re-use when there are no remains of lead in it.

Flat screen

The flat screen television basically the TFT has a complete different kind of monitor. Taking this apart will bring a number of very well recyclable plastics that are valuable ones the toxic liquid crystals are removed. The liquid crystals are collected and can be send away for destroying.

Separate systems for each type of TV

From both types of televisions the housing has to be removed. after that, the CRT can be treated in one machine and the flat-screen in another. It is not possible to do that in the same machine because the separation technique is very different. ATN designed two different units for that. Although they look quite similar on the outside they are very much different on the inside.
